The story isn't completed yet. The media wants us to see only one side of the picture where we see that SEC has finally sued CZ and he is no longer the CEO but was this game between Binance VS SEC  OR  CZ vs SEC ?

CZ stepping down as the CEO by no means tells that Binance's future is dark or the exchange will be less popular as time goes on. This is not going to happen in my opinion. It is not easy to shut down binance worldwide when it is the most liquid exchange at the moment. Also, I don't think the Blackrock or others may overcome binance, outside the US binance market is too much strong.
