Just now a friend told me that I worked hard on a one-year contract last year, but the last time the market plummeted and my position collapsed. I think many people have a mentality when it comes to making contracts. I used to have this mentality, which is to make money after losing money, otherwise they wouldn't be willing to accept it and would be kidnapped by sunk costs. As a result, the more we continue, the greater the potential loss. Sometimes stop loss is important, and those who can overcome sunk costs and stop loss are very impressive. I said as early as 2022 that I wanted to transform into the US stock market, and even my loyal fans know about it. But I didn't do it myself. I was still thinking about making a cryptocurrency for one cycle, and I was thinking about doing the US stock market for this cycle last night. At that time, the US stock market was playing with it, mainly focusing on cryptocurrency. In recent years, cryptocurrency has become different from before. I have become more and more skilled at harvesting leeks, but of course, it can also be said that my level is not good and my skills are inferior to others. I admit it. By early 2025, after the Spring Festival, I will have made up my mind to completely leave cryptocurrency. My own reflection and summary is that losing money is not the most important thing, what is important is wasting time and missing out on the great market trend of the US stock market. If I had been involved in the US stock market a year earlier, I would have gained an additional year of experience and understanding. 2022-2023 is the beginning of an epic market for the US stock market, and at that time, cryptocurrency completely missed out on this epic market. By 2025, it will have a high position and price. Fortunately, Trump had a chance to bargain in April. For example, starting in 2020 and now having 7 years of experience in the US stock market, it's very different. The US stock market can always be played with, the more experience the better. Cryptocurrency is just a stage of human speculation, and sooner or later it won't last.
