Binance still become the number one of best cryptocurrency trading, volatility and volumes should become the main factors to determine which is the best exchange site to trade because of most of traders are looking from the volume to get the best liquidity.
I think OP didn't say that it is in order or one is better than the other but I am sure some is. OP says its a list of the best. I think the list is great and it gives me an idea of where I should try trading. I'm planning to do trading and I have used Okex before. I'm actually shocked to see it in OPs list. It's actually a pretty good exchange.
