Do you want to trade or do you want to mine ?? if you want to do mining, a tool is needed. but if you only want to trade all you need is funds and an android or laptop ...
Laptop is better for trading as well actually i don't use android for trading. Especially i like to enjoy trading in binance and kucoin exchange. Actually my first trading start in binance after few month later i look like kucoin almost in prl. Both like there was good trading platform and stay impressfull there platform performance.
I can't trade on mobile, and I can't trade on laptop eather. I need a big screen so I can have chart from TV and exchange order book opened. I also checked his profile, he actually does what you say.
You are correct, laptop or pc is very suitable for trading in my opinion, and i think professional traders must be do trade in the big screen. Firstly, mobile never operated smoothly all of things. All of ppl aren’t own personal computer, they using in Android. I would like to prefer binance is trusted and smoothly working in everywhere likes pc or mobile. Even don’t forget they have safu fund.
