Which other can you add to Binance platform so that I have two to choose from or have option B.
Other than Binance, you can choose exchanges like
Changelly,
Poloniex, and
Coinswitch. I have used all these exchanges, out of these I would prefer Coinswitch exchange because it is an exchange aggregator. It supports many leading exchanges like Binance, Changelly, Hitbtc, OKEx, Changenow, etc. Here you will have an option to choose the best rates by comparing the rates across exchanges and trade at the best rate. It supports around 300 coins and no KYC or AML is required to trade.
