I'm looking for an app where I can buy and sell bitcoins at market rates (or the closest to it) with minimal (or dare I say no) fees.
Preferably an app that has alerts, charts and comprehensive analytical features.
Appreciate any pointers!
I think you should search no more and just consider checking Binance exchange out, I think they still meet all the requirements that you need so far, when it comes to great analytical platform, I think Binance has it, very simple to use charts and tools for trading which are equally self-explanatory, and if you talk about minimal fee which I bet you cannot get any zero fee trading platform anywhere, but when you want an exchange where you can buy coins and also trade coins at a very minimal fee, I think Binance still remain the king because of their large users database, and the volumes of trades the do record which enables them to be able to beat down the cost of their trading fee to almost something that is almost zero. Coinbase is also great but with high fee.
