i'm one who spend too much time for trading. I made so many stupid mistakes because of thinking emotionally instead of logically.

what is your opinion?
Its not bad to spend much time in trading, the bad thing is if you spend too much without gaining anything or you are juat making non sense. Mistakes is one thing that gives us experience. You need to set aside your emotion in trading crypto currency.
I think you are on point here, spending time on trading or doing short trade or scalping is exciting but of course big risk is always involved.This is done by experienced trader who has vast experience in trading wherein hey can buy and sell and gain within a short period of time.
