In the past, many people asked me how to trade, and I would enthusiastically say a lot; now when someone asks me how to trade, I will simply answer: I don't know either. The summary of this change is that a few years ago, when I just learned some theoretical knowledge, I had a strong curiosity and a desire to show off, combined with my perception of "single" factors, and under the overall lack of understanding, I had many expectations and fantasies about the future, so I kept talking endlessly; as time went on, when my knowledge base and experience grew richer, when I could speak incisively and understand that a tiny change could lead to ten thousand consequences, I no longer spoke lightly. The process from nothing to something is also hard to describe. Industry insiders can discuss specific issues, but for newcomers, the suggestion is to consider leaving the circle. #BTC
