Full time crypto trading is very profitable for crypto users because it can earn a huge money if you have a big funds for it since market is in good condition until now.
It should be regardless of the market condition because the decision belongs to trader whether he should quit his job or not. The decision should be based on your crypto earning status, if it look cool then dont hesitate to quit your job. Many traders who feel that they are now good at trading then they leave their job and the decision has nothing to do with crypto because they are doing very well.
Personally I saw only those who were losing more, unfortunately. How do that traders succeed? Are they trading manually?
