Just to tag on, there are some ONLINE CUSTODIAL services THAT YOU SHOULD NOT BE USING that only allow 1 transaction per address.
If you (or anyone) send anything else to that address then they keep it. Full stop.
Just a heads up on that. Not your keys, not your coins.
Never ever give out addresses that you do not have the private keys to. Paying 100 extra TX fess because all coins come into your control before you send them elsewhere is better then loosing that 1 TX because oops, that address is no longer valid.
Same with you sending out of exchanges to someplace else. Exchange -> you -> wherever. Or you can wind up having this happen to you:
