But I would say people who hodl on to coin end up earning more than most of day of traders. But it also depends on strategy as a experienced trader know what to do during bull, bear and sideways and swing market conditions.
It does not depend much on the strategies but traders that risk low and leave their trades for long time like swing traders do are the ones that make money most in trading which is kind of a little similar to trading. Holding is always better or have the mindset of not selling while losing but make sure you trade good coins like bitcoin and only buy when the market really fall significantly. Also to short while the market has significantly increased and use not more than or not up to 1x margin.
