I am just curious why you only stated Binance? And it seems you are like a hater of Binance exchange?
There are many exchanges with the same cases and you must understand that there will be no exchange with a perfect security system.  
You must be fair to review the current cases on exchanges.

Anyway, we cannot determine the future of crypto exchanges by analyzing a problem on a single exchange only, right? Even if Binance is the biggest crypto exchange now, but it cannot reflect the condition on all crypto exchanges in the world.
