This article is pretty much my logic for bottom fishing in this wave of market. Although I didn't make a lot of money, at least I integrated knowledge and action. My current operations are more inclined towards investors. I have already left the period of time when I made my fortune in the cryptocurrency circle. If you really ask me what I am pursuing, it can only be to cross another class. So I am relatively stable. I was afraid of encountering a black swan when the market fell like that before, but I was still willing to use the profits to make some small attempts. I think luck also played a certain role in this win, and the second was my own analysis and understanding of the market. Don't be modest and say that I made money this time by luck. Do you really think I was lucky?
