Trading is a skill that takes time and practice.
If you enjoy it and are able to learn something or make some profit, it can be worth your time.
But if you aren't having fun, or making a living, there are plenty of other things you can do with your time.
You can earn just as much from other jobs or hobbies.
These people simply aren't made for trading and should quit immediately. They however don't seem to realize that.
I think it's mainly due to the fact that it is similar to what gamblers are experiencing when losing. If they for example lose $100, then they will try to win it back, which can basically go on for quite a long time. Exactly that is also the case with people making loss after loss with trading. They are trying to gain it back while in reality they sink deeper and deeper.
