Never use any exchange's wallet for storing your crypto unless you have the intention to sell those coin in very short term or you are an day trader because you are not controlling the private keys so if the exchange gets jacked then all the fund will be gone.Even if you have 2 factor authentication on it still can't resist the exchange from hacked.In case if your exchange got hacked you need to follow their announcement on social media because they might give some refunds as well.

Ofcourse it goes against all fundamentals of which bitcoin was once created on, but that's not really the argument i'm making here.
