there are so many Crypto currency site in internet what are the best

The best centralized exchanges include Bittrex, Binance, Bitifinex, and I suppose Poloniex as well. I forgot to mention Bithumb they are good too.

For decentralized exchanges I really only know two and that is Etherdelta and also Waves. I don't use the DEX often either other than Etherdelta from time to time for arbing.
