Recently, some people have been telling me that the cryptocurrency industry has become more diversified into American stocks, so it's better to just play in American stocks. I didn't argue. Thinking back to this time last year, my friend also said the same thing: the market for DaA is so good, why are you still struggling in the cryptocurrency circle? He showed me his account and it was indeed very popular. I believed it, took one million and rushed in with him. What was the result? In three months, I lost over ten thousand yuan. It's not that Big A is bad, it's that I don't understand at all. The impact of policies on sectors and the fundamentals of individual stocks, I feel like a newcomer to the casino, betting on chips without even understanding the rules. I don't know why I made a profit, and I don't know why I lost even more. The current US stock market is indeed good, but to be honest, I don't understand it either. What do I know? I am familiar with the cryptocurrency industry. I know the fundamentals of a project, how to analyze on chain data, and when to enter and run. These are the real money paid for tuition fees in recent years. Some people say we need to step out of our comfort zone, but I think there's nothing wrong with staying in our comfort zone when it comes to making money. Every year, steadily earn some money in your area of expertise. That's enough. I will continue to research the US stock market, watch the excitement, and learn, but I will not easily end up in the future. It's not that I don't like it, it's that I know how much I weigh. People can never earn money beyond their cognition, this is the lesson I learned by spending tens of thousands of yuan to buy it myself.
