Binance is doing great volume and has many happy customers. It seems to have everything everyone could ask for in an exchange. Good tokens and good volume.

But like was previously mentioned... The withdrawal fees are the most common complaint. As far as I know these fees go straight into their pocket and are not burned. This is why they don't seem to be in a hurry to lower them. A good solution would be to have tiered fees.. less than $1k pay a higher fee inn order to reduce the amount of little transactions
