In 2017, a legend emerged in the currency circle, that is, there was a big brother in the Netherlands named Didi Taihuttu, who took his wife and three children to liquidate all the property in his family and exchanged it for Bitcoin. 1. They spent all their money to buy Bitcoin. The crazy Bitcoin family took out their profitable company, a large house of more than 200 square meters, cars, clothes, and even their children’s toys, leaving very little for their families according to the minimum needs. Didi Taihuttu’s family was called the “Bitcoin Family” by the media at the time. Then he took his whole family on a global "poverty tour". In three years, they traveled to 40 countries/regions, and continued to preach their support and belief in Bitcoin during the trip. Didi Taihuttu's family's actions were ridiculed as lunatics and mental disorders. They also experienced a long bear market. The choices of Didi Taihuttu's family were even more absurd and incomprehensible to people at the time. But later, the situation changed. Bitcoin has continued to rise, breaking new highs repeatedly, and has even been touching the $20,000 level. Didi Taihuttu’s family has confirmed their three-year “belief” with facts. Three years ago, when he attracted worldwide attention for investing all his money in Bitcoin, he said: "This experiment will continue until 2020. I believe that in these three years, our assets will at least triple." Didi Taihuttu did it. Bitcoin did it. The story of this family is more like a common comfort for people who are struggling to persevere in the bear market. 2. The cost was once as low as $900. He bought it when it plummeted, but did not sell when the price of Bitcoin rose. In an interview with CNBC, 42-year-old Didi Taihuttu said: “We got involved in Bitcoin because we wanted to change our life,” Taihuttu sucked more Bitcoin into his portfolio when Bitcoin prices plummeted in 2018. He said he remains convinced that cryptocurrencies are ready for a major rebound. “I think we will see a minimum peak of $100,000 in this bull cycle. I wouldn’t be surprised if it hits $200,000 in 2022.” In early 2017, Taihuttu bought his current holdings for $900. Most Bitcoins soon ushered in the bull market in mid-December 2017, with Bitcoin once soaring to $20,000.But Taihuttu has not given up his belief in Bitcoin. He is still buying Bitcoin at high points. But it only lasted for a month, and the price of Bitcoin fell by half, followed by the huge bear market in 2018. People in the currency circle still can't forget the horror of being dominated by the bear market in retrospect, especially the Taihuttu family who used their entire property as a stud. Difficulty moving. But the Taihuttu family is worthy of being a firm evangelist for Bitcoin investment. In the interview, he said: "When Bitcoin fell, we started to buy more." When asked what he thought of the current rising market and whether it was another round During the extreme bubble, Taihuttu said: "I don't think demand is going to go down." "I think we are facing a supply crisis." As Buffett famously said, "I am fearful when others are crazy, and greedy when others are fearful." As a more recognized investment product, Bitcoin has gained the favor of more and more well-known investors and institutions this year. 3. Different from 2017, “institutional bulls” have given the currency circle people confidence as the main force. Part of the difference between Bitcoin’s rebound between 2020 and 2017 is that institutional investors are now buying Bitcoin, and at the same time, the industry Regulation, legality and stability are also improving, and institutional support has helped Bitcoin shed some of its “unsafe” labels. "The rally in 2017 was largely driven by retail investors, whereas this year we've seen an influx of corporate entities and institutional money managers," said Mati Greenspan, investment manager and manager at Quantum Economics. Old-school billionaire hedge fund managers Stanley Druckenmiller and Paul Tudor Jones have both publicly stated their Bitcoin holdings, and large fintech companies like Square and PayPal are also embracing crypto products. Mainstream acceptance in the investment community is very important to the value empowerment of Bitcoin. Because cryptocurrencies like Bitcoin are not supported by fundamentals and lack the trust and endorsement of the government. In most people's minds, they are valuable because people believe in their value. Just like the Taihuttu family's choice. But now, Bitcoin has entered the investment basket of institutional whales, and the confidence of people in the currency circle has returned. The story of Didi Taihuttu's family goes from crazy to envied, but has a warm and heartwarming ending.For Taihuttu, the development of Bitcoin is not just about making money, he has donated half of the money to charity, and his family of five has been traveling around the world together for the past four years, paying tribute to Spread the bright future of decentralized digital currency around the world.

After many digital currency players make money, it becomes increasingly difficult to cash out USDT. Many gamer friends also received black money due to deposit and withdrawal issues, resulting in their bank cards being frozen, and demanded compensation of XXX yuan to the victims. At least at present, most OTC exchanges in China deal with black money every day, whether actively or passively. The most difficult part of cashing out deposits and withdrawals is the exchange of digital currency and legal currency. Pay attention to the following points to effectively prevent black money from being frozen: (1) Try to choose a large platform like Binance for OTC transactions. These platforms have better communication channels and risk control methods with mainland regulatory agencies and law enforcement agencies. (2) Try to choose an OTC platform that supports T+1/T+2 withdrawal strategy. Although you cannot withdraw money immediately after selling the coins, it reduces the risk of money laundering through OTC transactions. For example, Binance T+1 and Huobi Select Trading (compared to free trading, T+2 withdrawal). (3) Avoid directly using stable currency OTC transactions such as USDT. Try to use mainstream currencies such as BTC and ETH for OTC transactions. (4) The bank card used for OTC transactions must be a separate card that is not used normally and separated from the salary card. In this way, even if it is frozen, it will not affect the use of other funds. When cooperating with the investigation, it is easy to clarify the flow of funds. (5) Bank cards for OTC transactions should try to use cards from local banks, such as city commercial banks and rural commercial banks in various places. Large and medium-sized joint-stock and commercial banks such as Industrial and Peasant China Construction Bank have branches all over the country, so law enforcement agencies can basically freeze them directly. (6) Do not conduct frequent transactions with fixed merchants, and do not conduct frequent transactions with fixed users. It is very dangerous for the same user to make more than 3 indirect purchases in a day, or to sell a purchase a few hours later, and is highly suspected of money laundering. (7) Find reliable OTC merchants for transactions. Try to take the initiative to take orders from large merchants and market makers, place fewer orders, and touch less merchants in problem areas. In fact, as an ordinary user, it is difficult to tell which merchants are reliable. For example, a large number of friends who transacted with Huobi Blue Shield service merchants have also had their cards frozen. (8) Reduce the frequency of cash withdrawals and increase the amount of cash. (9) After OTC transactions, do not transfer it to your other bank cards to avoid contaminating other funds and making it troublesome to cooperate with the investigation.If you need money urgently, you can withdraw cash through ATM or spend it online. (10) Try to choose working days for cash out. It is best to trade during normal working hours such as working days, such as cashing out between 9 a.m. and 9 p.m. (11) Do not transfer money immediately after receiving it. After selling USDT and converting it into RMB, do not transfer it out immediately, keep it in the account for a period of time. The following are some of the more commonly used safe withdrawal methods, which can be applied to the withdrawal needs of ordinary users: 1. Overseas virtual bank cards There are already some overseas visa or MasterCard virtual banks that support cryptocurrency deposits, such as dupay and onekey card , gatecard (domestic IP cannot be used), etc. can use this method to deposit stable coins overseas, and then use payment transfer to withdraw funds through WeChat or Alipay. Of course, a certain handling fee will be charged in this process. For example, dupay's mastercard virtual card will have card fees every month. Finally, transferring US dollars to WeChat or Alipay also requires a certain handling fee, but the exchange rate loss is relatively low. 2. Withdrawals from exchanges. Generally speaking, what we call exchange withdrawals are C2C point-to-point withdrawals. With the increase in user demand, some exchanges have also started withdrawing money. For example, exchanges such as Binance specialize in Provides users with withdrawal channels. Let’s take Binance as an example. First, find the remittance option in the payment function, and then choose to transfer to China. There are three ways, namely Alipay, WeChat and bank. However, it should be noted that the account we transfer must be the same as our own currency. The security of real-name authentication is the same, which can avoid problems such as money laundering. 3. Direct consumption Another way is direct consumption, which is an indirect withdrawal. Currently, some exchanges have launched similar functions, such as Binance’s payment function and gift card functions, Gateio’s gift card. We can purchase Apple services or Steam services through the Binance payment function, as well as recharge mobile phone bills, book hotels, etc. Through the gateio gift card, we can purchase JD.com cards, Amazon gift cards, and Apple or more game services. Of course, Binance Payment also provides multiple consumption scenarios, such as payment functions related to purchasing Apple, recharging mobile phone bills, and multiple overseas consumption scenarios.4. Hong Kong digital currency ATM machines are in Hong Kong. Digital currencies can be used and traded normally. A series of policies to support cryptocurrency launched by Hong Kong at the beginning of this year are also being implemented, such as the launch of the hashkey exchange during this period. At the same time, Hong Kong It is also an area that is relatively easy for mainland residents to reach. They only need to apply for a Hong Kong and Macao pass. Of course, Hong Kong also has digital currency ATM machines, so we can directly exchange cryptocurrency into Hong Kong dollars at such ATM machines. Of course, according to the New Deal, exchanging cash from an ATM machine requires real-name authentication. Relatively speaking, the first operation is relatively cumbersome. At the same time, there will be a relatively high exchange rate loss through the ATM machine. It is generally suitable for travel consumption and other scenarios. Of course, if you go to Hong Kong alone, it is also recommended to apply for a Hong Kong bank card. Because Hong Kong’s cryptocurrency trading policy will continue to increase its opening up, it will become common to purchase cryptocurrency with legal currency, and it will naturally be more convenient to withdraw money. Therefore Preparing a bank card in advance will become a need to withdraw money.

Many friends who make contracts, whether they have been in the industry for a few years or are new to the industry, have a common problem. After an order enters the market, whether it makes a profit or a loss, they will feel anxious and hope to continue making money. Increase the profit, and hope that the order will be corrected if the loss occurs, so that there will be a situation of carrying the order. Many people are like this when making contracts and cannot hold on to their profits. Let me share the skills and general framework for making orders. I hope it can bring you some help. ① The size of the opening position. The size of the opening position is calculated based on your personal principal. For example, your 1000U Principal, if you open a position of several hundred U, then your risk estimate will be very high. If you open a small position, your percentage of profit will also decrease. Experience shows that the position size should be 5%-10% of the principal. Whether it is below 5% or above 10%, your risk and profit values ​​are not proportional to the rate of return. ②The expected rate of return of an order. When an order enters the market, for example, if you open a 100U position to go long ETH, at what percentage can the position be closed? My personal suggestion is 45% to 150%. Why is this profit range? Because after an order enters the market, no one can predict the market 100% in the long term, but the short-term direction can still be judged. Take ETH currently, 35 There is no problem with the market trend within 35 points, and the profit value can reach more than 100% with leverage of 35 points. ③ Daily profit or loss point No matter who you are, it is impossible to make 100% money when making contracts. Then you should set a short position warning period for yourself. What is a short position warning period? For example, your 1000U When the principal reaches 100U of profit, which is 10% of the principal, you can enter the short position period today. On the contrary, if you lose 100U, you will also enter the short position period. In this way, you will keep the profit and ensure the safety of the principal. , there is an old saying that goes well, if you stay in Qingshan, you will not be afraid of running out of firewood. This short position period seems easy to do, but when you actually practice it, you will find it extremely difficult. Because people are greedy. They want to make more when they make money, and want to get back their money when they lose money.In fact, this contract can be done every day. You cannot be greedy for temporary profits or dwell on temporary losses. ④ Have a certain understanding of the basic trend of the market and combine it with personal strategies. Many currency friends who make contracts, when making contracts, whether they are long or short, they open positions based on their own personal guesses and their own feelings. If it goes up, go long, if it feels like it will go down, go short, if you place an advance order, if you see that the current market has not entered your personal expected area, then you will fall into anxiety. This is definitely not advisable. Then there is an understanding of the market trend, and then there is the ability to read the market. The ability to read the market cannot be explained in words. You can only rely on yourself to accumulate it over time. The ability to read the market still depends on yourself. The other aspect is strategy. What is mentioned above can be considered a type of strategy. When making a contract, you must have your own strategy. Without a strategy, no matter how good you are, you will always fall into trouble. Welcome to search the public account: Analyst Muzi

Whether you are a newcomer or an old person, whether you are a new leek or an old leek, stock trading or currency trading, you need to follow some laws, achieve self-discipline, and conduct self-management in order to go further in the market. There are many things that you need to follow to win in the currency circle. Today I would like to share with you one of them, which is also the most important point, two words - mentality. Whether it's stock trading or currency trading, if you have a good attitude, everything will be fine. What kind of mentality is a good mentality? Not to be happy with things and not sad with oneself means not to feel happy or depressed because of the good or bad of external things and one's own gains and losses. Don't be happy with things, pay attention to a calm and calm mentality. Not being sad for yourself is a state of mind, and you must maintain an open-minded and calm mentality. There is a rhythm in currency speculation. If the mind is confused, the rhythm will be messed up. If the rhythm is messed up, it will be sold when it is time to buy, and it will be strange to choose to buy when it is time to sell. It is not a loss. At any time, if you can remain calm and calm, you can deal with it calmly and with ease. ‍How to do it? To be honest, it’s not easy to do. It’s quite difficult. This requires a long-term process of practice and accumulation. It is a process of mind cultivation and cultivation. First of all: don’t borrow money to speculate in currencies, otherwise you will be psychologically stressed. If you don't make money today, you won't be able to pay off your credit card tomorrow. If this is the case, your heart will not be at peace, and your actions will be chaotic if your heart is restless. Furthermore: when losing money, it is normal for every operation in the market to lose money. When losing money, it is the best time to cultivate one's mind. I just temporarily store the money in the currency circle. Sooner or later, I will lose money. Got it back with interest. Then: When making money, don’t let joy go to your head, and keep your mood calm. Why did I win this time, and where did I win? Is it pure luck, or did I catch that key point? Finally: To live with awareness, you must observe every operation you make as an observer, and your mentality during every operation. You must be aware of your emotions at all times. Once the balance of your mentality is broken and reaches an arrogant height or a sad valley, you must always restore your emotional balance to a balanced state. In the process of currency speculation, if your mentality cannot be adjusted, it is no longer under your control. To describe it in one word, you are confused.what to do? The best way is to leave for a while, go on a trip, relax, and then return to the market when your mood gradually recovers. Don’t ever be at odds with yourself at this time. If you’re having trouble with yourself, you’re having trouble with the market. Even if you’re having trouble with the market, you’re giving money to the market. This is not a simple loss of money. Stock trading is a process of cultivating your mind. Once you cultivate your mind, you will find that the rising and falling technical indicators that you thought were very important in the past are no longer a big deal.

Spot and contract are two different trading mechanisms, just like stocks and futures, each with its own advantages and disadvantages. Different trading mechanisms have different operating methods, which can be understood as using different tools to make profits for you. Advantages of spot goods 1. Buying spot goods means that the goods belong to you. You can buy as much goods as you want. Even if the price drops sharply, the goods still belong to you. If the market rises later, you will still make money; 2. As long as the value of the goods is It is still there, and everyone still recognizes it, and even more and more people recognize it. Although it is uncertain how long it will take, we can still look forward to it in the future; 3. For currency lovers with lower risk appetite, the spot does not have any technical requirements. High, because you are interested in its potential for future appreciation and do not need to pay attention to price fluctuations (it should be noted that there are also coins that have returned to zero, and even spot coins are still risky). Advantages of the contract 1. Two-way trading, there are two directions: long and short. One more direction means one more choice, and one more choice means one more profit opportunity. Even if you place an order with your eyes closed, there is a 50% chance of making a profit; 2. The margin system is what everyone calls leverage. For example: a down payment of 1 million for a house only requires 30%. You only need to pay 300,000 to temporarily own the house. When the house price rises to a value of 1.5 million, When you resell it, it is equivalent to earning 500,000 with 300,000. If you have 3 million to buy 10 houses in this way, it is equivalent to earning 5 million. If the down payment requires 100% of the funds, you will need 1,000. Only a capital of 10,000 yuan can earn 5 million yuan. The high threshold blocks the opportunity for ordinary people to make a fortune. This is what everyone is familiar with as real estate speculators. The same applies to any investment. It also illustrates the advantages of the margin system. It can lower the threshold for participation and allow more people to have the opportunity to make big gains with small things; 3 . Hedging (also called risk hedging), for example, if the same price is 100,000 yuan, if you buy all spot stocks and the price is 10,000 yuan, you can buy 10 pieces. When the market price drops by 10%, you will lose 10,000 yuan. And if you use 50,000 yuan to buy 5 spot stocks, then use 5,000 yuan margin to open 10 times leverage, buy a contract worth 50,000 yuan to go short, when the market price drops by 10%, the spot loss will be 5,000 yuan, and the contract profit will be 5,000 yuan, which can just offset the loss. No loss, no gain, this is hedging;4. Ignore the bulls and bears. Whether it is a bull market with a sharp rise or a bear market with a sharp fall, it has no impact on the contract. As long as there is enough room for the market to fluctuate up and down, there will be opportunities to make profits; 5. Opportunities to get rich because of leverage. Due to the attributes of small and large, theoretically, it is possible to obtain tens or hundreds of times of profits at low cost. In the bear market, it is no longer possible to buy dozens or hundreds of times of coins. The previous chaos has become history, and there are only contracts. Only the market has this opportunity, which is why the global contract market transaction volume is so huge. Everything has two sides. After talking about the advantages, let’s talk about the disadvantages. The disadvantages also need to be paid attention to. Disadvantages of spot 1. You get what you pay for, and the leverage ratio is 1:1. Since the spot market is a unilateral market, it is highly dependent on price increases. Either you can make money by rising unilaterally, or you can buy low and sell high to earn the price difference. It’s not good to be trapped in the same trap, especially in a bear market, if you are accidentally tricked by Gouzhuang again; 2. There are too many currencies, and it is difficult to distinguish the various news. The project team's IQ in writing stories and white papers is much higher than the poor seven-second memory of leeks. Once you get on a pirate ship in a bear market, it will be difficult to think about it. The probability of the small air currency eventually returning to zero is very high. If you feel that the risk of contract liquidation is high, then what’s the difference between coins that have been reset to zero? It’s just boiling frogs in warm water; 3. Time cost and opportunity cost, I think many friends experienced it deeply in 2018 and 2019, and their hands fell by 80 It doesn't make much sense to sell more than % of the currency, and the wait is far away. You can only passively comfort yourself that as long as the currency is there, there will still be a chance. Even if it doesn't return to zero, if you wait for 3-5 years to get back your capital, what is your original intention of speculating in the currency? What is it again? If you are trapped in a high position, theoretically you will not lose money as long as the price rises back later, but in fact, if you calculate the time cost and opportunity cost, the price is also very high. Disadvantages of the contract 1. It has high technical requirements. If the direction is wrong and the margin is insufficient, the contract will be liquidated. The margin is equivalent to the deposit. When the market fluctuates greatly and the deposit is not enough, it will be liquidated. Technical analysis, position There are greater requirements in terms of management and mentality control; 2. Behaviors such as malicious insertion of exchanges and malicious market control by large investors will pose a threat to our assets. Of course, sometimes it is unfavorable and sometimes it is beneficial. This also depends on luck. Overall, there are still risks. Then again, what can you do without risks?Contracts are not the devil, they are just tools. Just like a kitchen knife, when used in the kitchen it is a kitchen utensil, and when used in a fight, it is a murder weapon. How to use it correctly is what we should pay attention to and think about. Technical analysis, position management, point selection, stop-profit and stop-loss, mentality control, etc. are all very important aspects of contract making. These all determine whether we can make good use of this tool and whether it can bring us huge profits.

1: The essence of investment is cognitive realization, making money = sufficient cognition x efficient realization 2: The three cornerstone strategies of investment: improving cognition, efficient realization, and integrating knowledge and action. 3: If you lose money, it is either a cognitive problem (lack of cognition, cognitive bias) or a realization problem (motivation problem, action bias), or a mismatch between knowledge and action. 4: Investment requires the unity of knowledge and action. This is a very simple truth, but it has stopped many masters. It is because there is still a gap between cognition and action, which is human nature. Top masters can separate themselves from greed, anger, and ignorance. Top masters have no humanity, only principles. 5: If you are playing the game of chasing ups and downs with air coins, don’t imagine that you can use it to change the world. That’s because you are delusional. Take a shorter view. 6: If you are investing in Bitcoin, don’t just look at the minute line, look at the larger cycle, look at the overall situation from 2011 to 2018 from US$2 to US$3,000. 7: Before 10 million, you could speculate and pursue high returns, but after 10 million, you can speculate and pursue high returns. What you need is investment. Speculation is about fast in and fast out, while investment is about slowly compounding interest. 8: Many people find it difficult to cross the gap between speculation and investment. Once they experience the excitement of fast in and fast out, they can no longer adapt to the loss of making money slowly, and will eventually give their money back. 9: Investment is a long-distance race in life. It doesn't matter how fast you can run, but how long you can run. Soros and Buffett, they run slower than many people, but they have run for decades. 10: Soros outperformed the index by 18% for 40 years; Buffett outperformed the index by 12% for 57 years. If investment also has a peak period, they are like Messi and Ronaldo who have been at their peak for half a century. 11: The best investment in a bear market is to invest in yourself. If you have knowledge but no money, you can make money. If you have money but no knowledge, you can lose all your money. 12: The bull market investment trend makes profits flow, while the bear market investment itself upgrades cognition. 13: If you lose money, it will be worth it if you turn the lost money into knowledge. As long as there is awareness, a thousand pieces of gold scattered will come back again. 14: Investing in yourself not only costs time but also money. Many people are willing to spend millions on air projects, but are unwilling to spend hundreds of dollars investing in themselves. 15: The fastest way to spend money to invest in yourself is to get to know people who are better than yourself and invest with them to become a community of interests.16: Focus on things that don’t change and you can see things more clearly. The price of Bitcoin is changing, but its underlying logic has not changed. Bitcoin is a disruptive way of storing value. 17: Investment must follow the trend, but think in reverse. When the market peaks, the market sentiment is almost non-short; when the market bottoms, the market sentiment is almost non-bullish. 18: Carnival is on the edge of collapse and is suitable for taking a stand; winter is a gentle cool night and is suitable for moving forward indulgently.

When speculating in currencies, many people will encounter a problem when adding positions. If I add positions and the market continues to fall, wouldn’t I suffer even worse losses? But if I don’t increase my position and the market goes up, wouldn’t I suffer again? Such a choice puts many people into a dilemma when speculating in currencies and adding positions. In fact, there are certain methods and techniques for adding positions in currency speculation. 1. Add positions step by step. 2. After confirming the trend, don’t hesitate to add positions boldly. 3. After falling for several days, there will be a small increase. 4. Add positions after a slight decline. Just add less, and when there is a sharp drop, add more, chasing orders is something you must learn. Chasing orders requires certain methods and skills. Purchasing orders generally occurs when the currency price fluctuates violently. At this time, there are also huge risks, so of course there is also greater risk in pursuing orders. How can this risk be minimized? Let’s briefly talk about the principles of chasing orders. 1. Choose the time to pursue orders. Purchasing orders is mainly done when the market currency price fluctuates violently. Therefore, the time to choose for chasing orders is when the currency price starts to fluctuate very strongly up and down. How to judge when currency prices start to fluctuate violently? The main presence is when the position is broken. Breaking the position mainly refers to the combination of breaking the position of all K-lines. Specifically, it includes support levels, channels, pressure levels, etc. 2. When to choose to close a position after chasing an order? According to long-term market observation, we found that under normal circumstances, after the currency price breaks, the price will move in the direction of breaking a few points depending on the currency. If we When we choose to follow orders, we will close the position when we make a few points of profit. 3. Specific operating skills Normally, when the currency price fluctuates violently, we place an order. If the order we place will change when the transaction is completed, your order will be at the same time as when you originally placed the order. s price. Another thing is that the price will fluctuate faster when we perform currency speculation and order chasing operations, so after our order is completed, we should immediately set a take-profit price. In this way, the transaction can be automatically completed after the exchange rate reaches the take-profit price.The main purpose of this is to prevent investors from missing the best time for trading due to their own greed. When speculating in currencies, I want to accurately grasp the skills of adding positions. In fact, in short, there is only one thing, that is, we need to have an accurate judgment on the later development of the market, and if a wrong judgment occurs, we should not make too many unnecessary mistakes. Loss.

1. In-depth analysis of these four words, many investors have simplified them, and two of them are impressive, one is Buffett and the other is Duan Yongping. They all expressed it from different angles, such as "don't vote if you don't understand." In fact, it is not easy to achieve these four words, especially in the currency circle. We often see some projects that we don’t understand and don’t know, but they just keep rising, and we can’t help but ask people why. Up? Can I still buy it? In fact, this is a sign that investment has not yet started. Buffett missed Apple, Google, and even Bitcoin in the early days (he and his old partner Munger hated Bitcoin deeply). People often laughed at Buffett during his investment career, but Buffett missed a lot, and it did not affect him from becoming the last one. winner. Duan Yongping said that he never invests in things he doesn't understand. At the same time, he also emphasized a very simple logic. If you can't explain the benefits of a project in three sentences, either you don't understand it, or it's not worth investing in. That is to say, "understanding" actually means that it should be concise and easy to understand, and you can understand it as soon as you hear it. Only in this way can there be broad consensus and dissemination. For example: When Bitcoin was spread in the early days, there were some concepts including limited total supply, digital gold, fighting against inflation, etc. Some of them may not be so accurate, but they have been deeply rooted in people's hearts. Ask yourself: Can you explain clearly in three sentences a certain currency you want to invest in now, and will it be widely recognized now or in the future? 2. Think independently When it comes to investment, you must always start from practice and don’t be superstitious to anyone or any theory, including of course don’t be superstitious to Buffett. The so-called in-depth analysis deserves special emphasis on one thing: independent thinking. Buffett does not understand Bitcoin, but considering that he is already a centenarian and cannot even operate a computer proficiently, his views on Bitcoin are not worth referencing. For example, he believes that Bitcoin is a bubble and speculation. , these are all wrong. In the eyes of traditional investors, all cryptocurrency investments may be arbitrarily defined as speculation; within the cryptocurrency circle, there are also various biases, such as believing that those who buy and hold BTC for a long time are investors, while those who chase new coins It's speculation and so on.In fact, these are terrible and stupid prejudices. To be a smart investor, you should keep an open mind and realize the limitlessness of technology, but also the limitations of human beings. It is better than Buffett, Munger and others who could not understand Apple at first and then the currency circle. All are normal. How to distinguish investment from speculation? On the one hand, we must strictly follow the principle of "based on in-depth analysis to ensure the safety of principal and obtain appropriate returns"; on the other hand, we must "maintain an open mind, persist in independent thinking, and continue to learn new knowledge." For example: Don’t simply buy BTC as investment and buy new coins as speculation. 3. Beware of speculation. It is of great significance to distinguish investment from speculation, because speculation will definitely encounter heavy losses, and when one does not clearly distinguish this point, they will not wake up and grow even in losses, they will continue to A lot of risky speculation is done in the financial field. However, it is undeniable that most of the time, the investment products we buy will have some speculative attributes. Speculation is not a moral issue, but it may bring greater losses. Recognizing this, we must prepare ourselves financially and psychologically for both the short and long term. Beware of three hidden speculations: First, you think you are investing, but you are actually speculating. Is there any in-depth analysis? Can the safety of principal be ensured? Is there any chance of getting an appropriate return? The so-called "don't invest if you don't understand" means Buffett is an investor. He doesn't understand Bitcoin, so he doesn't invest. This is the implementation of his lifelong philosophy. Similarly, you understand Bitcoin and are optimistic about the future of blockchain, but if you invest in a currency without thorough research and only decide to enter based on some so-called benefits, then the final result will be different from all speculation. The result is the same: heavy losses in the end. The second is that they do not have enough knowledge and level to regard speculation as a serious matter rather than a pastime. From a conservative perspective, all leveraged trading is speculation, and so are most people rushing into hot new projects. There is a lot of fun in this kind of thing, including making tens of thousands of dollars "easily" with the help of certain news and a 10x leverage in contract trading. Some people even joke that making money is as easy as breathing;Including new coins soaring dozens of times in one day and so on. But as a smart investor, please remember at all times that if you participate in these activities, you must treat these activities as a kind of entertainment, a pastime, control your positions, and participate with the so-called mentality of returning to zero. Please remember one thing: Never increase your investment because of the rise in the market or the surge in profits. At this time, you should leave or at least withdraw the principal to your investment account. The third is to work hard with heavy positions, and once the loss occurs, it will be unbearable. As mentioned before, there may inevitably be more or less speculative factors in any investment behavior, and there is a possibility of losses. As strong as Buffett, he has a lot of loss records in his life. If he takes a heavy position in any loss and loses his principal, he may never be able to turn around again. Readers are requested to be especially vigilant. The currency market has experienced sharp rises and falls, and myths about getting rich overnight abound. Everyone needs to remain vigilant and not to take heavy positions at any time. The more opportunities there are, the more traps there will be.

1. Mistakenly believe that you can get your money back after losing ten times. The truth is: the more you lose, the harder it is to get your money back. The essence of a contract is to win more and lose less, to earn less and lose less. For example: if you trade 10 times with a principal of 10,000 yuan each time, you will be right 7 times and wrong 3 times, you will be able to continue to make profits. Win more often and lose less often. The more you make, the better, and the less you lose, the better. This is the realm pursued by technical analysis. 2. Misunderstanding that the opening point is not important, but the closing point is the key to profit and loss. The truth is: even if it is good, but the order opening point is not good, you still can’t make money. The essence of a contract is to pursue precise entry points and precise exit points to minimize risks and maximize returns. For example: The big pie is bought for 3700 and sold for 3800. If the position is too small, you cannot make money. The position is large and there is slippage, so in the end you will not make any money. If you wait patiently until 2900 points to enter the market, is there a good profit margin? 3. Mistakenly believe that if you set a stop loss, you can place an order against the trend against the support pressure. The truth is: a good trader always goes with the flow. The essence of a contract is not to be absolutely long or short, but to be a slippery man, and always know how to stand in the team of the few. Although some experienced hunters often use this method to make some short-term profits, the risk-reward ratio of this method is not attractive. And it requires veteran hunters to have very rich experience and skilled skills. If you were really an experienced hunter, would you still place an order against the trend? For example: I still remember how much the Air Force was buried under the heavy pressure of 6,000 points in the pie at the beginning of 2019. 4. Mistakenly believe that stop-profit and stop-loss are the core of the trading system. The truth is that stop-profit and stop-loss are only one component of an excellent trading system, and technical analysis is the soul. The essence of the contract is to use stop-profit and stop-loss to prevent the occurrence of small probability events, so as to use probabilistic thinking to make sustained and stable profits. Most people often know nothing about technical analysis, or have been using wrong trading methods. The key is that they don't know it, which is the most terrifying thing. Many people think they understand the technology after learning a little bit, and they can judge the effectiveness of the technology without shame. This is not rigorous enough. If we want to judge something, you must at least understand it deeply before you can make a judgment.This is just like you point to the waves in the ocean and say, this is technology. The waves are only a few meters high on the surface of the ocean, but the deepest part of the ocean is more than 10,000 meters. The deep layer without any waves is the main body of the ocean. 5. Mistakenly believe that setting a stop loss is safe. The truth is: As everyone knows, unreasonable stop loss settings or wrong market entry points will cause you to stop losses frequently. The essence of a contract is to set a stop loss at the most certain trading opportunity to provide the final layer of risk control for your own judgment. If you stop losses frequently, what you have to do is to reset yourself, re-examine your trading system, and rebuild it from scratch. 6. Misunderstanding that stop loss is harmful because the loss comes after the stop loss. The truth is: Stop loss must be set, and we cannot doubt the methodology because of our own mistakes. The essence of a contract is that the market will always be unexpected. If you think stop loss is harmful and do not set stop loss or frequently fail to execute it, even if you escape 99 times, there will always be one time that makes you miserable. For example, if I cut my finger when cutting vegetables with a knife, can it be said that the problem is with the knife? It must be a problem with your own method. When you often cut vegetables, you will slowly come to the conclusion that the technique of cutting vegetables well, cutting them quickly, and keeping them in hand is exactly the same as trading. When you don’t know how to cut vegetables, shouldn’t you find a chef and ask for advice humbly? Otherwise, you can only use your own fingers to verify your judgment, and you will be to blame for your injuries.

There are roughly two types of people who make big money in the currency circle: 1. Relying on cultivation; 2. Relying on discipline; relying on cultivation. People with cultivation should have the following characteristics: they can see the truth clearly, they have faith and they are responsible for themselves. 1. They can see clearly. The truth is that this is quite difficult. We have grown up under a uniform education model, and the awakening of independent thinking has been delayed for a long time. The search for the truth comes from independent thinking. Most people just listen to the media and follow public opinion, swaying in the wind like duckweeds. If it happens that someone you trust leads you astray again, you will only be living with lies and mistakes for even longer. How many people have clearly seen the truth about Bitcoin? What’s really great about it is the technology or the economics behind it. 2. Have faith. Having faith is based on seeing the truth. The faith mentioned here is not a religious or superstitious belief. Of course, the target does not necessarily only refer to Bitcoin, as many people in the currency circle believe that public chains and cross-chains are the future of blockchain. Everyone can have their own beliefs based on their own vision. Only faith can allow people to hold a worthwhile currency for a long time. Some people say that the last bull market brought Bitcoin completely into the mainstream, and the task of the next bull market is to bring some of them into the market. In this way, only those who have the faith to hold the currency are qualified to enjoy a greater bull market. If you enter the market early, your costs are low, you know the technology, and even if you are a code contributor, you may not be able to hold on to it and you may not be able to make Bitcoin money. What kind of person earns it? Those who have faith: For example, Teacher Li, he knows that this thing is not something that can happen overnight, so he has to be patient and take time to be friends and make money through other things. Make money and buy coins. For example, the Nine Gods are those who are obsessed with Bitcoin. He has also been making money in other fields, and the money he makes is good for him. For example, for some entrepreneurs, buying Bitcoin is just a configuration, like Ding Lei. People who are not short of money believe in this thing, even if it is just an experiment. In the end, I found out that people who have faith and don’t rely on it to make money have made a lot of money. So we say that when investing spare money, you must be able to get it. 3. Be responsible for yourself. Not much to say. The first rule of a qualified investor is to be responsible for his own investment.Pay for your own decisions. If you lose money, you will blame everyone and act like a giant baby, and you will not make any money. In a free market, no one will put a knife to your neck and ask you to buy coins. Don’t fantasize beforehand and don’t complain afterward. There is no regret medicine in the world, and this has always been the case in the investment market. After all, there are only a few people who have achieved cultivation through discipline. Even cultivation requires time. Sometimes opportunities wait for no one, what should you do? Then it can only rely on discipline. Of course, the premise of discipline restraint also requires online awareness. Otherwise, you will be out of the game in minutes. If cultivation is not enough, discipline will help. We often say: make friends with bubbles. Where there is a bubble, there are opportunities to get rich. Make friends with time. Investment must be cyclical, sowing seeds in bear markets and harvesting in bull markets. The middle is patience, just be friends with time. Be friends with boredom. Fixed betting is not fun or exciting at all. But it can guarantee basic income. You must know that most people lose money. As long as you agree with the above three sentences, you can abide by the rules. The hardest thing about observing discipline is seeing other people's coins go up while your own coins stay the same and fall. I saw others cheering and jumping to different stages, but I was alone with a flower. I really feel itchy, so I use 10% of my spare money to buy emotions and sell facts. After writing down the reasons for your operation and the plan for taking profits and losses, it’s time to practice. Nothing wrong with that either. As long as you don't strain your muscles and bones, just be aware of it. Therefore, be friends with time. In the short term, others will be proud of you. In the long term, others will see you having the last laugh.

Can you get rich by simply hoarding coins? Can you achieve financial freedom? This is a question many people have. The answer is actually very simple, that is - yes. But many people have mistaken the really important part of the question, which is: can you hoard coins? In fact, this question is not just one question, but three questions. 1. Do you really understand what “hoarding coins” means? There are two saddest levels in hoarding coins: money and loneliness. Needless to say about money, if the money you hoard coins is very important to you, I advise you to give up as soon as possible, because you will not even be able to pass the first level. Because when you watch the price rise and fall every day with fear, believe me you will completely collapse at a certain moment one day, sell Bitcoin and bid farewell to your currency hoarding career. This moment may be an extremely fanatical surge, it may be an extremely scary plunge, or it may be a continuous sideways darkness. When you have the idea "Can I make a swing to earn more coins?", half of the wall of your ideal coin hoarding has collapsed. And if this money still has little impact on you, and you have successfully passed the first level, the second level is: what happens when the price of the currency rises to a point where it has a great impact on you? What if this money could allow you to buy a nice car that had appeared in your dreams, move your family to a better house, and provide a better educational environment for your children? It's hard to decide. In addition to money, perhaps the more important thing is loneliness. I believe everyone has felt how lonely and misunderstood hoarding coins is. Especially when your friends who have been hoarding coins together are cursing each other and leaving the currency circle, the media can’t find a single good word about Bitcoin, and your closest relatives advise you that you might as well invest in something else. 2. What is your purpose of hoarding coins? When you insist on doing something, spend time, energy, money and other costs to do it, and you have to restrain your impulse at all times, then you need a very high goal to persevere. So what is your goal in hoarding Bitcoin? If this goal does not have some idealistic feelings in it, and is simply a material need, it may be difficult to persist until the distant future. Those who can persevere are those who firmly believe that they can change the world.If you don’t believe it can change the world, you firmly believe that it will rise to the price you have in mind. As soon as you have even the slightest doubt about your purpose, your coin hoarding career will be almost over. 3. What is the basis for your currency hoarding? Hoarding coins requires a certain material foundation, which is also easy to understand. For example, the first level in the first question just now requires that the money you hoard will not have any impact on your life. The second level is when the price of Bitcoin rises enough to change your life, how do you make a choice? The better your material foundation is, the later your second level will come. This is why the rich can afford to hoard a hundred, one thousand or even ten thousand Bitcoins. The impact of "money" on people has a diminishing marginal effect. A simple understanding is that when you are worth tens of millions and have multiple properties, only when one Bitcoin reaches one million will it create an "irresistible temptation" for you. But if you are an ordinary working-class person who lacks everything, it is estimated that it will be difficult for you to resist if Bitcoin rises to 100,000. Therefore, it is very, very difficult to expect financial freedom with Bitcoin. Anyone who can insist on holding Bitcoin from 100 to 1 million must have strong self-control. Such a person will succeed even if he does not need Bitcoin.

1. In one step, hoard coins at high prices. In 2013, a large investor entered the market. He immediately bought a lot of Bitcoins at high prices. Throughout the bear market in 2014, he kept trying to keep buying to lower the average price of his positions, but he never bought the bottom. At the last 900 yuan During the crash, he stopped buying, which perfectly conforms to the currency buying logic of most leeks in the currency circle. After experiencing a long bear market for three years, in the 17-year bull market, he sold continuously at the beginning of the bull market, perfectly missing the subsequent increase, and achieved the achievement of "sell and rise". It can be seen that if we want to hoard coins for a long time, we must have a good attitude. If it is not a fixed investment, but a one-time high position, no matter how long-term investment is advertised, it will still be difficult to control the anxiety before the book is at a loss. Therefore, investing your own money that will not affect your life even if you lose it, or making small additional investments in the long term, is a strategy more suitable for ordinary users to hoard coins for a long time, so that they can hold on to it. 2. Improper storage and loss of keys. We often hear that people lose their mobile phones with digital wallets due to various reasons and cause property damage. It can be seen that the security of blockchain assets comes from the private key. If the private key is forgotten, no assets will be lost. Although most people back up their private keys and mnemonic phrases, not many people have actually restored them. They are often frightened and overwhelmed after an accident. As for the mnemonic phrases and backup files, they have long forgotten to save them in Where is it, so many times the currency really leaves us like this. Although Bitcoin is now very valuable, due to various reasons, millions of Bitcoins can no longer be recovered. Should we keep our own digital assets ourselves or put them on the trading platform? If you put it on the trading platform, it may be stolen by the trading platform, or the trading platform runs away; if you keep it by yourself, you are afraid that something unexpected will happen to you one day, and your family will not know your wallet private key, which is equivalent to permanent loss. Of course, how to save it is a matter of opinion, and everyone is different. What I want to express is that don’t wait until your wallet is lost and then regret it. You can usually try to restore the wallet, teach your family how to use digital wallets, and stay vigilant. Having a sense of vigilance is the greatest protection.3. Not having enough perseverance and giving up halfway. In a bear market, very few people are willing to invest. Even if the price of Bitcoin keeps falling, the number of people willing to buy Bitcoin for US$3,000 is far lower than the number of people who buy Bitcoin for US$10,000. All aspects of investment are declining. Facing suffering. In fact, the biggest problem has nothing to do with the bull market or the bear market. It is that the decision when buying is the result of one's own thinking, rather than entering the market after hearing about the case of a big V or a wealthy person in the circle of friends. There are always a few people who have their own opinions, follow the plan, and swim against the current. When they assess the situation and follow the trend, they must add their own understanding to judge, and finally verify their cognition through operation. And only firm perseverance can truly avoid giving up halfway.

1. July 6, 2022, an extremely ordinary Wednesday. Programmer Xiaosan finally finished the final contract test, spun around in the artificial chair, and stretched out excitedly. "Okay, next is another task today - building and deploying an Ethereum pledge node." Two months later, Ethereum is about to usher in Merge. Xiaosan has a full 289 ETH in his wallet, and he plans to transfer them Take it for pledge financial management. "But there seems to be a bug in the ledger wallet today? Forget it, let's go to the account where I deployed the contract. Anyway, publishing and testing the contract will also consume some gas." After typing the transfer script, Xiaosan went to flush it. a cup of coffee. An ordinary latte, just like an ordinary Wednesday. After returning from making coffee, Xiaosan started to refresh on Etherscan while drinking to see if the transaction just sent was confirmed. "Huh? It seems that the payment account is not right?" Suddenly, the waiter's heart skipped a beat, the coffee in his hand fell to the ground, and the cold feeling in his hands and feet suddenly came over him: "It's over! I sent 289 ETH to Hardhat for testing. The account is in!" 2. Hardhat is the most mainstream and commonly used development framework in Ethereum. It provides a series of tools and functions to facilitate developers to develop, test and deploy smart contracts on the Ethereum platform. For developers, one of the most important functions of Hardhat is to create or fork an Ethereum environment locally for local testing of contracts. When you execute the npx hardhat node command locally, Hardhat will create a simulated network locally and generate 20 fixed test EOA accounts and corresponding private keys. At the same time, Hardhat will also initialize the balance of 10,000 ETH for these 20 EOA accounts to facilitate developers to use these accounts to publish local contracts for testing. (Having 20 accounts "worth hundreds of millions", I'm the king of localhost!) Note that this local simulation network has nothing to do with the Ethereum mainnet. The 10,000 ETH balance on these 20 EOA accounts is only local. Up. However, since the 20 generated accounts are fixed and the private keys are public, anyone on the Ethereum mainnet can use these private keys to withdraw the assets in these accounts.If an engineer forgets to switch the environment after completing the contract test, treats the test environment as the main network environment, and sends ETH to these 20 test accounts, then a tragedy will happen... 3. As described above Just like that, on July 6 last year, a sum of 289 ETH was sent to the Hardhat test account 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 by a friend of threepvault.eth. Why is this account 0xf39F? It is the first test account generated by Hardhat, so it is the most commonly used. So it is speculated that this unlucky programmer copied the first test account to complete the test, but forgot to switch the configuration and sent 289 ETH to the address of this test account on the main network. If calculated based on the currency price at that time, 289ETH was worth 340,000 US dollars. Now it is worth more than 500,000 US dollars, a tragedy of 3 million yuan. What happened next? Let’s take a look at the data on the chain: This erroneous transfer occurred in block 15086827, which was still the POW era of Ethereum. This block is a Flashbots block, and a MEV Searcher luckily caught this Backrun "opportunity". This erroneous transfer was entered into a MEV package, and the arbitrage transaction followed closely. After paying the gas fee of 4.8 ETH, the remaining approximately 284 ETH in the Hardhat test account 0xf39F was transferred to the account 0x043D. From 100ETH to 10ETH to 1ETH, and finally not even 0.1ETH was spared: At this point, this asset worth 2 to 3 million yuan should be regarded as a piece of cake that has gone into the sea and will never come back. 4. Forty minutes after the tragedy occurred, our victim came online. He sent an NFT to the hacker. This NFT is called Message In a Bottle, which can package a piece of text into a picture and cast it into an NFT. In this NFT, he described his journey: hello I was tring to stake a validator nodetonight. Had to send eth to a hot wallet due to a ledger bug. Thought I was sending it to my contract deployer wallet.. turns out it was a public hardhat test account.I'm typically pretty careful (hw wallet, send small test transactions) but was careless tonight. Feels bad man.On the off chance you see this, I'd love to try to negotiate a bounty or something similar. I made a really stupid mistake Translation: Hello, I want to stake a verification node tonight. Due to a bug in the ledger, eth had to be sent to the hot wallet. I thought I was sending it to my contract deployment wallet..(Only after the transfer was completed) I found out that it was a public Hardhat test account. I'm usually very careful (hardware wallet, sending small test transactions, etc.) but was careless tonight. Feeling bad. If you see this, I'd love to try negotiating a bounty or something similar. I made a very stupid mistake 5. But the hacker ignored the victim. Five hours after the tragedy occurred, the owner of the 0x043D account, the MEVSearcher hacker, came online. He skillfully began to transfer assets, split up the 284 ETH, and transferred them to Tornado one by one. 6. However, , the story does not end here. 15 hours after the tragedy, our victim went online again. After losing 289 ETH, I don’t know how the owner got here in the past 15 hours. Now he should have accepted the reality of losing 289 ETH, but he has not fully accepted it. The owner purchased an ENS domain name called willpay100ethiffundsarereturnedtothreepvault.eth (if you return the money to threepvault, I will pay you 100 ETH), and sent the domain name to the hacker and made his offer. Maybe he wanted to convey the message in this way, hoping that the hacker would find out with conscience or show mercy and transfer 189 ETH back to him. In March 2023, more than half a year has passed since the tragedy occurred. There has been no action on the hacker's address, no transactions have been issued, and the victim's account has not had any entries from Tornado. I think this story ends here and there should be no follow-up. This is the dark forest, no one will pay for your mistakes, everyone can only believe in themselves.
