A friend of mine made his first big money by trading cryptocurrencies, and then bought a house and a luxury car in a first-tier city. Initially, he only had 30,000 yuan as capital, but through continuous rolling operations, his money grew more and more, from 30,000 to over 10 million. The key to this is knowing when to buy and when to sell. Let me share some methods:

Whether in a bull market or a bear market, 50% of your money should be used to buy BTC and ETH, while the remaining 50% can be used to seize those opportunities that might yield big profits. When the bull market adjusts, many altcoins will drop significantly in price, with some going down to 10% or even 1% of their original value. At this time, pick those altcoins that are widely recognized and have development potential, and buy them, then just wait for the bull market to heat up again.

In a bull market, many hotspots will emerge, such as the current trends in artificial intelligence, gamefi, RWA, public chains, and platform tokens. You can invest a small amount of money to follow these hotspots. If you make more than five times your investment, quickly take your profits and convert all your money into BTC and ETH.

Now let's talk about selling, which requires some technical skill. Don't always think about selling at the highest price because you only know afterward when that was. Here’s a more reliable selling strategy.

This is the target profit-taking method, which means knowing when to be satisfied. Nothing can keep rising indefinitely; fluctuations are the norm in the market. You can set a target for how much you want to earn or at what price you want to sell, and then place your order in advance.

For example, if you plan to buy a house that costs 1 million this year, you can set a price that will earn you 1 million, and when the price reaches that point, it will automatically execute. Another method is to use the historical highest price (ATH) as a reference, because it’s generally difficult to break through the previous highest price. Once it approaches a breakthrough, there is often a significant drop. Therefore, you can set your sell order about 5% below the recent high.

Finally, let's talk about holding cash, which is the highest realm of cryptocurrency trading. In a bull market, focus on a few narratives that are strong, with powerful communities and endorsements from celebrities. Don't be greedy; learn to focus.
