Well this was the pre-mine address: DT6pLH6RJgxZESbEsuFj1DCR3qJBJgQejK

But the coins were sent to the Bittrex wallet for....."security".  Seems super weird that the coins from the pre-mine would be sent back to a different wallet in smaller chunks...but that's just me.  I'd be willing to bet the pre-mine was dumped when the coin hit the exchange and if indeed that's the dev's wallet, they were bought back when the coin bottomed out and put back into that wallet, but really who knows.  Not like it matters now, coin is all but dead.
