Every trader or at least most traders have what i call a trading weakness , the trading weakness could be greed , it could be over-trading , the trading weakness could be FOMO all the time , the trading weakness could be over-confidence on the market , the trading weakness could be extreme analysis on the market etc...
So it is left for you to discover what your trading weakness is or what your trading weaknesses are , then start working on it so that you can become a better crypto trader..
As for Me , my own trading weakness is the fact that I become too emotional when trading on the market , I allow my emotions to be among the major factor that determines the type of trading decisions I make on the market at any moment , for example whenever I make an analysis and I believe the analysis is great, I allow myself to get carried away by the emotions and then I will suddenly become over-confident on the market and I will go ahead to trade based on my analysis, even if the whole world warns me against certain trading decisions , I won't even bother to hear what they have to say or at least hear their own opinion , and this has made me fail on the market several times..
It is a weakness which I am working on because I need to ensure I work on it if I really want to be a successful trader...
