Trading cryptocurrency on mobile phone will be much more easier if you generally depend more on fundamental analysis for trading decisions.
You can see indicators and tools on an exchange app on a mobile phone which can be enough for analysing the market. But having it on computer would be better. What I meant is that if someone dies not have a laptop, he can still use the exchange app in the mobile phone to make technical analyses. If the person is good, the person will still use the phone to make money from trading.
