My Polkadot coins are staked on Kraken exchange but I have a whiteaddress - this means that even if the exchange gets hacked, the coins can only be sent to an address owned by me (my Ledger).
Check to see if that exchange you are using has a similar feature.
To the unitiated oik like me the above is totally impenetrable.
