Trade too much
To be real there are many traders who loves doing multiple trades and at multiple coins too, it just depends on the person if you can handle the pressure and a lot of time for those trades. Yes, it is really hard but trust me it will be easy if you love doing multiple trades and trading many times a day.
You have to be skilled first before anything else, and then you could manage every situation where you at in Trading, all of it. Skills are your strong fortress that will help you in gaining profits in the process. I have a friend of mine who is a professional Trader, he do Day Trading and what I stan about him is he don't care about how much he lost in a day, he only cares how he could take it back the next day and double it, and it help me realized that skills will give you confidence and you could overcome any hard situation in Trading.
