Leveraged trading is a strategy that uses borrowed additional funds to increase the size of a trade, thereby increasing potential gains but also increasing the risk of potential losses.

In cryptocurrency trading, leverage allows you to trade with more than you actually put in. This is done by borrowing money from exchanges or other traders. For example, if you use 10x leverage, you can trade 1,000 yuan with 100 yuan. This means that your profit will be calculated based on your total trade volume (i.e. 1,000 yuan) rather than your actual investment (100 yuan). So, if the trade goes well, you can make more than you actually put in. In the above example, if your trade generates a 10% profit, you will make 100 yuan (10% of 1,000 yuan) instead of 10 yuan (10% of 100 yuan). This is why leveraged trading can increase your potential profits.

However, the risk is also increased accordingly. If the transaction goes against you, your loss will also be calculated based on the total transaction volume. Using the above example, if the transaction loses 10%, you will lose 100 yuan instead of 10 yuan. What's worse is that if the loss exceeds your actual investment, you will also need to pay the excess. This may cause your loss to exceed your actual investment, which is called "explosion".

Contract trading is a financial instrument that allows traders to buy or sell a predetermined amount of cryptocurrency at a price at a certain time in the future. This price is called the contract price, and the date when the contract is bought or sold is called the expiration date. This form of trading often involves leverage, which means using a small amount of money to control a large amount of assets. This form of trading is often used in futures and options trading. In the cryptocurrency market, contract trading is often executed through so-called "smart contracts", which are self-executing protocols programmed on the blockchain.

There are two main types of contract trading: futures contracts and options contracts. A futures contract is a standardized contract in which the buyer and seller agree to trade a specific amount of an asset at a specific price at a certain time in the future. An options contract gives the buyer the right (but not the obligation) to buy or sell an asset at a specific price at a certain time in the future.

The potential benefits and risks of this type of trading are greater. Because you only need to pay a small portion of the contract value as margin, if the market moves in line with your predictions, you will earn more than you actually invested. However, if the market moves against your expectations, you may lose more than you actually invested. This risk is even more significant in the cryptocurrency market, as this is a market that operates 24/7 and is extremely volatile.

It is important to note that this article is only for basic concepts and does not constitute any inclination or advice. Whether it is leveraged trading or contract trading, there are great risks. You must ensure that you understand and can bear these risks, and use rigorous risk management strategies, such as understanding the type and terms of the contract you are trading, setting appropriate stop loss points, and keeping a close eye on market trends.
