As you call it, my trading is based on technical analysis. It's much better when you can calculate and predict everything yourself. In this case you can not blame anyone. Now I'm using Changelly Pro and it gives me a bit more profit then my previous exchange.
how exchange give you profit will you elaborate more? at changelly you can not able to exchange all type of cryptocurrencies, but at Binance or any other exchange you can able to exchange almost all top-level crypto. personally i like to use binance as my regular use of trading,beside Binance i also use kucoin.
