Yes, i also use Binance, Kucoin and Bibox Android Application to trade. Rather it is easy for me to bid buy and sell order. Applications are very good and well managed by the team, no need to worry, you can use regularly
Previously, I also used Binance's application for cryptocurrency transactions, but the numbers were much more variable and slower than the live trading on the Binance website so I no longer trade on mobile apps. I use mobile only to see the chart of values and set the quotes for the coins I follow.
I think it's normal for people to trade on mobile. well, even though I don't do it at the moment, but many people do that. Well, I think it's more practical and can be used anywhere as long as there is still an internet network. but so far, I think most crypto trading applications on mobile are paid, am I wrong?
