It seems to me that today there is no need to consider the question of whether to leave or remain in trade. If you have already decided to trade once, then you need to continue to work, especially to gain experience and learn more information. Bad times are always on the cryptocurrency market, but the results depend only on our work.
I think the OP is experiencing a dilemma of despair because for the past two years he has got nothing. Indeed learning to trade is hard, but we don't have to study according to books or youtube, it should have been able to analyze the market in the past 2 years. It's useless if you just follow the tutorial without being analyzed and developed again.
I have repeatedly witnessed where a person without formal education, on his own, learned and gained extensive experience in the cryptocurrency market, where he became a professional trader and at the same time his results are very high. therefore, I also believe that it is not the most important thing to read books and watch YouTube, but rather to really work on achieving results and improving my practical experience. but nevertheless it still depends on the psychological state of the person and what results of the trade he had before.
