Saw a couple interesting charts put out from another poster on here: penguinpablo
These are the transfers of steem to and from Poloniex and Bittrex.
As you can see a lot of steem is leaving Poloniex and a large portion of that is making it's way to Bittrex.
The question that remains and on most people's minds is probably how long will Poloniex wallets be enabled this time?
The charts came from here:
