I think emotion is the greatest problem of a newbie trader. We all have gone through this while starting up but because of experience we can now discuss it as something not very serious but emotion is very serious and need to be put in perspective. One of the ways to work out the fears or emotion is to learn good money management. We fear of our emotion because we don't want to lose our money, so in the same light, if we use stop loss we will do better. However, this is difficult for a new trader to totally leave out emotion while trading because sometimes an experienced trader has same fear.
Any trader that can't control their emotions shouldn't be trading because if you ignore the fact that you have a problem and still be trading, your emotions will make you make decisions that would be destructive to your trades. Emotional traders can't be a successful trader, to be successful at trading they have to learn to separate their emotions from their trade so they can make the right calls on when to exit the market or keep holding.
Any individual that has decided to go into the path of trading cryptocurency, you first have to eximained yourself to make sure you can make decisions without your emotions interfering because the market is manipulated to mess with traders leading them to panick buy or sell.
