The first rule is to sell one-third when the price increase of the wave exceeds 30%. The second rule is to sell another one-third when the price increase exceeds 50%. The third and most important rule, which is the core determinant of whether you can make a profit, is that if you buy on a given day and the next day there are unexpected circumstances that cause the price to break below the 60-day moving average, you must exit completely and not hold any unrealistic hopes. Although the probability of breaking the 60-day moving average through this method of selecting coins based on monthly and daily charts is very small, we still need to be aware of the risks. In the cryptocurrency market, preserving your principal is the most important thing. However, even if you have sold, you can wait until it meets the buying conditions again to buy back. Ultimately, the difficulty in making money lies not in the method but in execution. "When the price directly breaks below the 60-day moving average, you must exit completely and not hold any unrealistic hopes." This one sentence has caused 90% of people to fail. In short, in the cryptocurrency market, one cannot be rigid; adaptability is the key to long-term survival in the market. Therefore, we must pay attention to the fact that the overall market and individual coins can be completely opposite. Trading cryptocurrencies may seem like competing with the market, but in reality, it is a battle against human nature. The risks you see on the surface may actually be opportunities, and sometimes what appears to be an opportunity can be a trap designed to tempt you.
