I heard the news about Bithumb being hacked, it's sad and I hope they refund the stolen funds. Exchanges need to take security very seriously.
I don't see it as sad. If they can't protect their funds on cold wallets and are making the withdrawals automated because it costs too much to employ a real person to manually check them, much like it's done in a real bank, they will have to cover the losses from their own pocket. There's been so many hacks that security on exchanges should be constantly improving. Real life casinos have teams constantly watching the floors and coin exchanges are earning millions of USD a year and can't even get proper security.
