It's easy to combat when you just like Bitmex process withdrawals manually due to there not being any hot wallets. After so many hacks I expected more exchanges to stop working with hot wallets, but it seems that they don't want to stop offering people the convenience of cashing out near instantly, and it will require a little more work in the background.
People want the convenience but blame the exchange for not being secure after a hack. After a hack however people suddenly would wish the exchange didn't work with hot wallets if they had the chance to go back in time.
