The biggest reason for losing money in a bull market is: being too anxious and too impetuous
The logic of bull and bear markets is completely different; in a bear market, there are only a few good assets, so you need to look more and seek various information to find the real key
The biggest problem in a bull market is that all cryptocurrencies are rising; today you buy this one because it went up, and tomorrow you switch to that one because it went up, and in the end, you end up with nothing
Therefore, when the big trend is clear, choose a few and hold them tightly, blocking out the noise.
