Wow. That's pretty bad...
Not necessary.
Of course, this is an unpleasant incident for the team (and a great shame if it turns out that the keys for multisig wallet were actually stolen from one man), but it also might even turn out to be a good way to demonstrate the benefits of DPoS algorithm even if rollback doesn't work out, the delegates will not allow the project to fail due to lack of funds.
Well it looks like the price hasn't dropped that much even though 18 BTC buy walls are gone. Good thing deposits are disabled...
Yeah, but deposits/withdrawals are disabled and major amount of SHIFT coins are stored on native wallets, not on exchanges. Let's see what will happen after the issue will be resolved. Anyway, SHIFT team has already proven that the project they're doing is at least is proven working and is demanded by market, so even if we'll see a huge dive it will be a great opportunity to fill the bags in anticipation of future growth.
