Today I saw that a friend in the currency circle has 20,000 U in his Binance account, and there are dozens of currencies in the "self-selected list"! He said that some of them have been studied by himself, some are recommended by others, and some are reluctantly discarded after playing! I sincerely suggest that he clean it up. The point of collecting so many coins is to be afraid of "missing out", but this mentality can easily backfire. Seeing the rise, you want to chase after it, and when it falls, you want to increase it. This can easily disrupt your own trading plan, and in the end you may not be able to catch any of them.
