I made my first big money by trading cryptocurrencies, then bought a house and an X5 in Suzhou. Initially, my capital was only 30,000 yuan, but through continuous rolling operations, the money grew more and more, from 30,000 to over 3 million. The key here is knowing when to buy and when to sell; I'll share my method with everyone.

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 opportunities that might earn big profits.

- When a bull market pulls back, many altcoins become much cheaper, some even dropping to 10% or even 1% of their value. At this time, choose those altcoins that are generally recognized and have development potential to buy, and then wait for the bull market to heat up again.

In a bull market, many hot sectors emerge, such as this round's artificial intelligence, gamefi, RWA, public chains, and platform coins. You can allocate some small funds to follow the trends and trade; if you earn more than 5 times, quickly take profits and convert all the money into BTC and ETH.

Now let's talk about selling, which requires a bit more skill. Don’t always think about selling at the highest price, because you only know in hindsight when the peak was. There is a relatively reliable selling method.

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 specific profit target for yourself or decide at what price you want to sell, and then set a limit order in advance. For example, if you plan to buy a house this year and need 1 million, then set a price that can earn you 1 million; 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 is generally difficult to break through previous highs. Once it approaches the breakthrough, there is often a significant drop. Therefore, the sell order can be placed about 4% lower than the recent peak.

Lastly, let's talk about being in cash; this is the highest realm of cryptocurrency trading. During a bull market, focus on a few narratives with strong communities and endorsements from well-known figures. Don’t be greedy; learn to concentrate. Recently, Dao Ge has been quietly holding a coin that Elon Musk promoted in the primary market, which has very high popularity and has been around for almost a year; it won't go to zero.
