So I just tried to withdraw all my coins by breaking it down in 5-10btc withdrawals. Half of them went through, the other half didn't show up in the blockchain. It seems completely random. I hope I will see the other half soon enough. I'm happy I got at least half safe and sound now though. I think what they should do right now is stop withdrawals until the current backlog is cleared. This surely won't be a popular move when they announce it but will likely help tremendously. They need crisis management right now.
