Binance is the absolute king when it comes to altcoin exchanges, but the thing that keeps people steering to exchanges as Hitbtc, is that they are more likely to list rubbish coins.

Binance has become stricter when it comes to listing certain coins, while Hitbtc and Yobit keep adding rubbish coins like they don't even bother to perform a basic check. It's only the potential fee income they care about.

The only way to get rid of these exchanges is to stop using them, but that's not very likely with how they manage to attract thousands of new users every month due to the stricter policies of the other exchanges.

It's an unstoppable process unfortunately.
