I am 30 years old this year, and looking back at the moment I stepped into the cryptocurrency world in 2019, I feel quite emotional. At that time, I wasn't financially well-off, and the 60,000 capital was borrowed. However, after several years of struggling in the cryptocurrency market, by last year, my assets surprisingly exceeded 8 digits, which can be considered a small achievement. I have been trading cryptocurrencies full-time for 6 years now, which adds up to over 2160 days. During this period, I have tried various trading methods, including long-term, short-term, ultra-short-term, and swing trading, so I can say that I have a fair amount of authority on cryptocurrency trading. I have always believed that to master a skill, one must follow the 10,000-hour rule. Take cryptocurrency trading as an example; if I spend 8 hours a day, with about 200 days a year for reviewing and summarizing, it would take nearly 5 years just to start achieving stable profits. It’s important to note that in these 6 years, I have inevitably encountered various pitfalls. Therefore, to be safe, everyone should not invest more than they can afford to lose. I have seen many experts who originally turned tens of thousands into tens of millions or even over a hundred million in assets. They relied on trading contracts with high leverage to seek profits, but after a bear market, all their assets were wiped out. There are plenty of such examples; many just haven't seen them. Human nature is such that, in the face of major market trends, it often leads people to lose their ability to make correct judgments. This brings us to a critical point about cryptocurrency trading: one must always set a stop-loss when opening a position. This is a hard rule! If you trade contracts without a stop-loss, it's no different from handing your money over to those who manipulate the market. Why bother? Everyone must not harbor any illusions about holding onto losing positions. You might get lucky and recover nine times, feeling good about it, but if you fail just once, you could lose everything. In reality, there are many people like this everywhere. Also, when trading cryptocurrencies, maintain a good mindset and do not get overly emotional. I have seen too many people who, once they lose money, rush to recover it, leading to chaotic and unplanned operations. What might have been a small loss can turn into a total loss overnight; how unfortunate! This goes back to the stop-loss issue. Before opening a position, you must think about the stop-loss level and know how much you can afford to lose. If the stop-loss is triggered, just let go, adjust your mindset, and patiently look for suitable opportunities. Do not let emotions guide you. Moreover, we cannot be too subjective when trading cryptocurrencies; the market will not necessarily move according to our own ideas. If you understand technical analysis, that’s better, as you can rely on technical indicators to make judgments. If you don’t understand, then you cannot have preconceived notions. I often see people thinking, “This is definitely going to drop; the manipulators are luring in buyers,” or “So many positive news, it has to rise; just hold on.” Isn’t that too rigid? The market changes rapidly, and you can’t rely solely on your feelings, thinking “I feel” or “I believe” is correct. Once you realize you’ve made a wrong judgment, quickly admit it, adjust your thinking, and don’t stubbornly insist you’re right; otherwise, you will end up suffering. In conclusion, the cryptocurrency market is risky, so everyone must trade cautiously, maintain a rational mindset, and strictly adhere to trading rules.
