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?
True, as newbies only have limited knowledge and no enough experiences before they start trading, so that put them into high risk of losing their capital. Controlling the emotions is the key, but you will never master it unless you are never exposed to the real trading scenario and that you only invest to gain profits and not to learn and master trading.
