Many of us make mistakes, yet sometimes we cannot identify that we still might be in a bad kind of mindset, so we keep making the same mistakes over and over, and staying involved in shitcoins or can's stop trying to trade bitcoin, which can be some of those kinds of mistakes that are hard to get away from continuing to make.
Not going to generalize this but I have noticed that most of the times when you see someone who actually is buying various shitcoins (something I can never call investment) and they probably have been losing money more and they still stick around this same strategy of buying they are people not making mistakes in my opinion but rather people who are actually trying to get rich quick by buying the next pump coin. Sometimes it is hard to actually hard to get this mindset off from them.
