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'm sorry but it's bull shit. Bitcoin is a highly volatile and unpredictable market, so results not only depend on work as you said, you're wrong. It's a little bit like saying your results at lottery depend only on your work...
