Just keep in mind that you will never be able to make the perfect decision in terms of buying or selling no matter what. But it's better to have a plan on what to do than not have any plan, which will lead to you either not selling or selling too much too early, or just generally not making good decisions because you will do it in the heat of the moment which is usually the wrong decision (in a bull market most people think it will go much higher than it actually does, and in bear markets, people will think the opposite)
I am trying to condense what I learned about crypto and investing over the last 5 years and what I found to be true within a short amount of words. In the last bull market I also made the mistake of almost not selling any crypto, which is not a good feeling
