Centralized platforms are not safe, you don't have full control unless a third party controls them, avoid them and choose your own wallet which is much better.

Investing in bitcoin is enough with a non-custodial wallet, I think every investor chooses this option rather than storing it on an exchange.
Even if you want to profit from the APY offered by the exchange, it won't be much if you save it there, I don't really recommend it.
