Let this be a lesson to you all. Exchanges are not banks! Most of these exchanges rely on opensource technology commonly available to anyone, including hackers. It was only a matter of time before they got hacked. Hell, they even said on the website that it was a beta. Bitcoin / Crypto is supposed to be the digital form of cash, right? So then treat it like cash! Would you leave large sums of cash with a stranger to hold for you in a box that anyone could get the key to? The point is, don't trust the exchanges to hold your money.
