I'm sure not all traders will agree with me but some could possibly be on my side...

Here are the reasons why;
 1. It is quite stressful - old traders will soon give up due to mental health problems
 2. It is not enjoyable anymore - nobody will stay long in a job that they no longer find themselves comfortable with especially if you are not earning well.
      Most of the time we feel this during bear season.
 3. Trust issue due to Scam growth - traders never find it safe to use exchanges, even big exchanges.
