Thank you nc50lc.
So, would I be correct in assuming it is safe to keep fiat on the exchange ‘wallet’, but not crypto?
It's the same for fiat and crypto, it's just not totally necessary to send it back to your bank if you're going to trade later.
The difference is if it's crypto, you have a better choice than holding it in an Exchange
because you will have the full control of your funds if you have the private keys of your addresses (
in a desktop wallet).
Don't worry, Coinbase so far is doing a good job on keeping hackers at bay,
the most probable issue that you might face in the future is the one I've mentioned in my previous reply.
