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?
In addition many people losses in trading because of greediness and I believe that its the emotions you are referring to, when you are crypto minded you will know exactly what is obtainable in trading, so I believe that trading have to do with mechanism and if you don't have the mechanism of Trading you won't know when is right time to take decision and when not to take decisions.
