Now, I use Binance P2P to sell my coin to my fiat currency and I also use Binance to trade occasionally. I do not use the other exchanges to trade normally or P2P crypto trading because I feel comfortable using Binance and I do not have a problem until now. About the rate, I do not think much about that because I am sure that every exchange will have a gap in the rate and I think every exchange will have advantages and disadvantages for that.
