I wonder will there be a full mobile version to trade? I think if you succeed to make a great mobile app, you will get many new users.
But now, mobile app, no surprise, many exchanges now operate modern mobile applications. However on iOS they are much smaller, but in almost every exchange there is an app for Android and with this, new users are unlikely to attract.
I agree with your opinion that most people use Android applications, but according to my observations, cryptocurrency mobile applications are not highly competitive.
