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.
If they fix the mistakes and not commit the other mistakes, they deserve to have a second chance to fix their mistakes. That will help them get more enlightenment about Bitcoin investment so they will not in a rush when buying Bitcoin for their investment. If they want to invest in altcoin besides of Bitcoin, that will not be a problem because they can pick what their choice and no one can force us to follow what they suggestion. Yes, it is hard to get rid of this mindset but they must try to do that because that will not be good for their minds in the future. They should not think getting rich instantly after they buy Bitcoin because Bitcoin investment need time before they can get big profit in the future.
