Investing in cryptocurrencies can be exciting, but security should be your number one priority. The crypto asset market, while innovative, is susceptible to scams and vulnerabilities. This practical guide offers best practices to protect your investments from the start. Protect Your Keys and Passwords Your private keys are your access to your funds. Never share them with anyone and keep them secure. Use strong and unique passwords for each platform and wallet. A strong password should contain a combination of uppercase and lowercase letters, numbers, and special characters. Consider using a trusted password manager to securely store your credentials and generate complex passwords.
I entered the market without understanding anything.
I didn’t know how the market worked, didn’t have enough money to trade comfortably, and got everything wrong at the beginning.
I learned the hard way, lost money, and made a lot of mistakes. But every loss became a lesson.
I stopped complaining and started studying for real. I spent hours learning, testing, and taking notes on what worked and what didn’t. I learned to trust the process.
Over time, I got better. Calmer, more strategic, more consistent. 📈
Today, my situation is completely different from when I started. 💰😎
And a lot of people ask me why I haven’t changed my name.
I haven’t changed it because that name reminds me of my journey. It reminds me of the losses, the difficult times, and the days when nothing went right. I’d rather remember than forget, because those experiences are what taught me. ❤️🩹📊
If I could give you one piece of advice: don’t jump into the market blindly. Study first, understand the risks, develop a strategy, and take care of your money.
Nobody gets good overnight. It takes patience, discipline, experience, and the humility to learn from your own mistakes.
I started from zero, learned by doing, and kept moving forward. You can too. Just don’t forget: protect your capital, respect the market, and never stop learning. 🚀💎
CRYPTOCURRENCIES: HOW NOT TO GET HACKED AND LOSE EVERYTHING
Everyone wants to make money with crypto. Few people want to study security. And that’s where they lose everything. If you’ve just entered the crypto world, write down these 7 golden rules:
*1. Your private key is your bank. Lose it, and it’s gone.* Whoever has the 12 words has your money. Never take a screenshot, never save them in your email, and never send them on WhatsApp. Write them down on paper and keep them somewhere safe. Offline.
*2. Hot wallet vs. cold wallet* A hot wallet (Binance, Metamask) is for everyday use. A cold wallet (Ledger, Trezor) is your vault. Left a lot of money on an exchange? You don’t own the crypto—the exchange does.
*3. There’s no such thing as support reaching out* Nobody from Binance, Metamask, or any exchange will DM you to “validate your wallet.” If someone contacts you, it’s a scam. 100% of the time.
*4. A fake link can steal everything in 3 seconds* One wrong letter in the link and your wallet is emptied. Always type in the address or use bookmarks. Never click an ad link on Google.
*5. 2FA is mandatory* Use Google Authenticator or Authy. SMS can be cloned. Without 2FA, your account is worth nothing.
*6. Test before sending everything* Going to send R$ 5.000 in crypto? Send R$ 10 first. Did it arrive? Now send the rest. One wrong network and your money is gone forever.
*7. Promises of fixed profits are pyramid schemes*
“1% a day guaranteed,” “a bot that never loses.” In the crypto world, anyone who guarantees profits is guaranteeing they’ll rob you. *In the crypto world, you are your own bank. And a good bank doesn’t leave the door open.*
Want to get rich? First learn how not to get poor.

*PRICES NOW - *BTC:* $82,800 — tried to break $85K yesterday, hit $84,800, then fell $2,000 in 6 hours. Critical support at $82,500; if it breaks, it could head toward $70K - *ETH:* $2,441 — rejected at $2,510, weaker than BTC today - *USDT:* $0.9993 — holding steady at $1
*THE 3 STORIES THAT MATTER:*
1. *GENIUS ACT — USDT IN THE CROSSHAIRS:* The OCC finalized stablecoin rules yesterday. Issuers like Tether will have to prove 1:1 reserves and process redemptions within 2 days. The law takes effect on Jan. 18, 2027. According to the U.S. Treasury Secretary, it's the biggest milestone since 1863. USDT has already lost $1 billion in market cap over the past 5 days because of this.
2. *WHALES ARE BUYING AGAIN:* Wallets holding 1,000 to 10,000 BTC have started accumulating again — shifting from -62,600 BTC to +5,230 BTC in 60 days. Binance's USDT reserves rose from $790M to $1.76B, but that hasn't translated into buying yet.
3. *ETH UNDER PRESSURE:* Ethereum ETFs saw outflows of $1.08 BILLION in October alone, the highest of the year. But developers have scheduled the Glamsterdam upgrade for testnet on October 26.
In the market, those who run from risk run from history. Every red candle scares you. Every green candle tests you. But only those who stay on the battlefield, sword in hand, write their name on the chart. No risk, no story. No courage, no profit.
The market doesn’t reward those who are afraid. It rewards those who can handle the risk and stay until the end... No risk, no story.

In 2016, Ethereum had a project called *The DAO*—it was kind of like a decentralized investment fund. It raised *$150 million* in ETH, making it the biggest crowdfunding campaign in history at the time. 11,000 people invested.
Then, on *June 17, 2016*, a hacker found a stupid bug in the code called “reentrancy.”
Imagine an ATM that gives you the money BEFORE deducting it from your account. You press “withdraw” again and again before it updates. That’s exactly what the hacker did—withdrawn 3.6 million ETH (about $50 million at the time) by repeatedly calling the same function nonstop. 58dd
*The plot twist nobody talks about:*
1. The stolen money was LOCKED for 28 days in a child contract. The hacker couldn’t withdraw it right away. That gave the community time to decide what to do.
2. The community had a HUGE fight: some said, “code is law, let the hacker keep the money.” Others said, “let’s turn back time and erase the theft.” The result: the blockchain split in TWO.
On July 20, 2016, at block 1,920,000, they carried out a hard fork. The chain that erased the theft became the *ETH we use today*. The original chain, where the theft was allowed to happen, became *Ethereum Classic (ETC)*.
3. And the wildest part of all, RIGHT NOW: some of that money was left unclaimed—about 75,000 ETH. Today it’s worth *around $150 million to $200 million* and will become a security fund for Ethereum. The money from the biggest heist in history will protect the network.
Vitalik was 19 when he created all this because the Bitcoin devs said “no” to his idea. He named it Ethereum because he saw the word “ether” on a sci-fi wiki and thought it sounded mysterious.
🚨 $BTC — THE DOWNTREND IS FINALLY COMING TO AN END. For over a year, Bitcoin has followed the same pattern: → A drop of more than 30% → A recovery of 20–25% → Another sharp sell-off But something has changed. The bearish structure is showing signs of breaking, and anyone waiting for another major bottom could be caught off guard. My roadmap: → $70K: Possible final pullback → Higher low: Key bullish confirmation → $87K: First major resistance → $120K: Next upside target I’m not chasing $BTC at current levels. I’m watching the $70K level for a possible accumulation opportunity. The biggest move may still be ahead. Follow me + 🔔 Don’t miss my next market analysis.
*1. TETHER BETS ON BRAZIL AND LATIN AMERICA 🇧🇷* Tether led an investment in Bolivian fintech Peso to expand USDT payments in retail. Announced today (21), the investment will accelerate USDT adoption in Brazil, Bolivia, Colombia, and Argentina, with local conversion on-ramps, POS systems for merchants, and virtual accounts. Peso already lets users pay for food orders in the Yango app with USDT and connects to local banks via QR and ACH. CEO Paolo Ardoino said the idea is to turn USDT from a savings tool into an everyday payment channel.
*2. USDT SUPPLY FELL ALMOST $1B IN 5 DAYS 📉* Liquidity alert: USDT lost about $1 billion in market value over five days as the market tries to recover. This is a divergence, not yet a lack of demand. From October 15 to 20, it fell from $183.87B to $183.06B. USDT balances on exchanges fell by $4.6B between July and October 1, with Bybit alone losing $1.66B.
*3. THE STABLECOIN MARKET IS STILL HUGE* Despite USDT’s decline, the total stablecoin market stands at $301.4 billion, up $1.6B over 90 days. USDT still dominates, with ∼61% of the market.

Spot Bitcoin ETFs see nearly $1 billion in outflows over two weeks
U.S. spot Bitcoin ETFs recorded net outflows of around $910 million over the past two weeks, pressured by higher-than-expected inflation data and expectations of elevated interest rates. Bitcoin’s price fluctuated below $82,000, near the average cost basis of ETF holders. Analysts say the market has entered a period of macroeconomic positioning, with attention focused on the Federal Reserve meeting and the U.S. elections.
Tether (USDT) is at the center of the biggest stories in the global and domestic crypto market. The biggest development is its aggressive expansion into Latin American retail, alongside impressive data showing its absolute dominance in Brazil and new international regulatory clashes. Here’s a summary of the most important USDT updates:
🚀 Tether invests in fintech to bring USDT to physical and digital retail
Tether announced a strategic investment, leading the initial funding round for Bolivian fintech Peso. The goal is to integrate USDT into everyday payments in Brazil, Bolivia, Colombia, and Argentina. The infrastructure will allow people to use digital dollars directly in food delivery apps (such as Yango in Bolivia), e-commerce, and physical retail, connecting blockchain to local banking systems.
🇧🇷 USDT’s absolute dominance in Brazil
According to the latest data released by the Federal Revenue Service, USDT has established itself as the most widely used crypto asset in Brazil, surpassing Bitcoin in transaction volume. • Stablecoins account for about 80% of the total reported volume in the country, and USDT alone represents 88.7% of that segment. • In the first half of the year, out of the total crypto transactions reported to the tax authority (R$ 283,1 billion), USDT accounted for R$ 199,5 billion. Businesses and individuals use the asset as a hedge against currency fluctuations and to facilitate fast international transfers and payments without relying on traditional banking hours.
*The biggest story: ETH amid a battle of narratives*
ETH is at $2,450 (+2.6% today), holding above $2,400 even after a massacre in ETFs. Look at the scale:
- *ETFs bleeding:* U.S. spot ETH ETFs have seen outflows for 15 days straight. October alone has already seen $1.08 billion in outflows, the biggest monthly outflow since November 2025. On Monday, $103.2M flowed out, followed by another $26M on Tuesday. Yesterday, BlackRock alone lost $117M
- *Record staking:* While institutions sell, holders lock up their ETH. Ethereum hit a record 43.8 million ETH staked, 35.9% of the entire supply. It’s the 6th consecutive quarter of inflows, with +1.99M ETH this quarter. Yield fell to 2.63% due to dilution
- *Hacker on the move:* Wallets linked to the April 2026 Drift exploit moved 44,510 ETH (∼$109M) to Tornado Cash in 2 days, and still hold 56k ETH
- *Bullish catalyst ahead:* The Glamsterdam upgrade is in 5 days, on October 26, on the Hoodi testnet. It will raise the gas limit from 60M to 200M, a 3.3x increase. JPMorgan launched JPM Coin on the ETH mainnet on the 19th. 519ce024b250582a0f8f
*Cryptosubc’s take:* Institutions are selling in fear, while the network is more secure than ever, with 35.9% locked up, and a major upgrade is coming. This is exactly the accumulation window we talk about: ETH is holding at $2,400 even as $389M flowed out of ETFs over 5 sessions. 1091
𝐒𝐓𝐎𝐏..... 𝐒𝐓𝐎𝐏..... 𝐒𝐓𝐎𝐏 🚨 $BTC THE NEXT ACCUMULATION WINDOW IS APPROACHING. Only 545 days left until the next $BTC halving. ⏳ A historical pattern is worth watching: 📉 500 days before the halving → Accumulation 📈 500 days after the halving → Possible profit-taking window 2016 ✅ 2020 ✅ 2024 ✅ History offers clues, not guarantees. If this cycle follows a similar timeline, the next major accumulation phase may be closer than most investors expect. The real question is: Will you accumulate when fear takes over, or buy when FOMO sets in? 👀 $BTC | Patience over FOMO. 💎
THERE WAS A TIME WHEN I’D GIVE YOU 5 BITCOINS JUST FOR SOLVING A CAPTCHA... AND PEOPLE THOUGHT IT WAS A WASTE OF TIME. Today, having 5 Bitcoins means having a house. That’s half a million dollars (depending on the market). It’s retirement money for a lot of people. But in 2010, Gavin Andresen, one of Bitcoin’s leading developers, wanted people to use the currency. The problem was that nobody wanted to buy it. So he created the "Bitcoin Faucet" (The #Bitcoin Faucet). It was a simple website. You’d visit, solve a little challenge (a CAPTCHA) to prove you were human, and click a button. Boom! 5 free Bitcoins sent to your wallet. You could do it over and over. People would visit, collect their coins, and then delete them or lose their keys because they "weren’t worth anything." It’s estimated that the site gave away 19,700 Bitcoins. Today, that would be worth almost 2 billion dollars. It’s the most brutal reminder that value is subjective and that generational opportunities often look like toys at first. If you could travel back in time, would you rather buy $AAPLB #Apple in the ’80s or spend an afternoon clicking that Bitcoin faucet? $BTC
