In trading the number one enemy is our self emotions, many trader loss because they can't control thier emotions and it really affects thier decision making and sometimes it will become a reason for the big loss, in crypto we cannot be free from different emotions because everytime market condition is changing and it is really a high volatility market, i think experienced had a very big role on decision making, is this a reason why most of the newbie loss is it because they don't have enough of experience?
This is why you have to be ready to take the risks and stop thinking that everything is a win. I'd prefer to suffer a loss in early runs to know how does it feel so I'm not that surprised if I encounter the same scenario again in the future. Keep winning is great but in the other hand if you can't handle one small mistake and ruined your emotions then what's the matter?
Failure is a part of success
