Re: Are altcoin price movements have some mathematical explanation?
It's seems, that you just using other strategy to do trading, not choosing to do TA, but trying new coins and waiting for the big pump. 
Yes. It's far less hassle and all you have to do is wait. I don't think full time trading is good for anyone's mental health.
On r/bitcoinmarkets the trading obsessives often seem to crack eventually and walk away. One of the biggest sold everything at around $800 a few days before the price really started to rise.
So before you consider TA, how much control do you have over your own emotions? Will you be able to take profit at the right time? Will you know when to cut your losses?
Without that control everything else will be useless.
