Can anyone suggest me for trading exchange because there is a lot of exchanges are available, I m little confused so please suggest me the best trading exchange.
It all depends on the token or coin. You just can't have only one exchange. If you know the token you want to trade, then go to Coinmarketcap to see where it is trading and the higher liquidity. But if it's to trade generally, I'll recommend Binance, Bittrex and for newer coins Bitforex and Idax.
