Bittrex has done this swap before multiple times with success, so nothing to worry about there. I still haven't heard anything from them yet though, so I plan on bugging them through IRC next The OP contains the latest news about the exchange swaps, and I always post updates AS SOON as they happen, so the info is reliable.

To the guy(s) with CFC sell orders on Coinano, move your coins as soon as possible, they're not participating in the swap and your coins will be lost
