for now I only recommend Binance or OKEx, because I feel annoyed because there is an exchange site for trading but when the price goes up he always maintains it by reason of hacker attacks. it's really annoying that we fail to get the high price. it's always the case and it's a classic excuse. but sorry I will not mention the exchange site because it is confidential.
Most people recommend exactly Binance when asked which trading site is best.
It looks like this exchange has become #1 worldwide and is far ahead of its closest competitors. Although I don't have that much experience in trading on various platforms, but Binance I like the most. I don't know if it's good or bad that 1 site is becoming so popular with everyone. I heard a story that a similar situation was with mt.Gox.
