It seems you can't trade using the app from binance, and the app from coinbase only allows buying and selling from an account for limited crypto currencies.
Can anyone recommend a good safe and reliable altcoin trading app from a reputable brand (i.e. not by a random independent developer)?
I do not use too many trading applications other than Binance because it is more reliable because sometimes other applications cheat and the authenticity of the application must be reviewed, yes it can return to everyone's taste because it involves the convenience and desire of coins to trade, so be a little careful in choosing trading applications because it is very vulnerable to any counterfeiting.
