2) Too much time.
Again, when you are checking value for 10-15 times per day it takes a lot of time. I was always tired and exchausted.
In trade, of course time is needed. Because if not you will lose the moment when you want to sell or buy one of the altcoins. Therefore in trading free time is really needed in order to always monitor the crypto market. If you don't have a lot of time maybe trading is certainly very bad for you. And chances are you can also suffer losses because you don't have a lot of time.
