As of my experience. Day trading is just fun from the start. Obviously you just got excited about it especially when you make profits.
There may also be sleepless nights just to monitor the movement.
But, as weeks/months go by and it became a normal flow to you.
It gets boring too and you will end up buying other coins just to pump the need to do something everyday.

I used OKex platform before but switched to Binance because one of the coins I trade have larger volume there.
Then, I stayed because I love the UI of their android application.  
KuCoin and OKex also have an android application. (not sure if there is IOS)
