"Back in February a user reported to us that somebody managed to access his wallet, and transferred all funds to Bittrex. Two more wallets of our top list got emptied, and more users reported theft in the days after.
Over a million SHIFT went to the market and got dumped. We did all we could to investigate, and talked to Bittrex for countless hours since that moment. But despite all efforts to receive the stolen funds back, we haven’t seen 1 SHIFT yet."
