Does Coinbase really use the same hot wallet for multiple users? Because that is a really bad practice that I thought we had stamped out long ago. You should never send payment to a third party directly from a shared wallet, you must always transfer it to a wallet controlled by the user first. You don't even have to wait for a confirmation, because you're only trusting yourself. Honestly, I expected better from a company with over $100 million in VC funding. It's not like they're some sketchy Russian exchange incorporated in the Cayman Islands.
