Just don't store (the majority of) your coins on exchanges (for very long).
The 'for very long' thing does not matter. Just FYI. The exchanges pay out until the very second they don't pay out. If you think you will just move quickly through that, you could easily get your coins caught. And I wouldn't be surprised if a near-fail exchange can see big movement real time and selectively halt anything they want.
Yes get your money the hell out of any exchange as quickly as possible, but that's not a secure trading method.
This is a major weakness of bitcoin right now. There just is no safe way in and no safe way out. Almost completely Illiquid.
