You are the guys who continue funding the exchange with your money so that it steals it and the scam continues to live on. HitBTC is already proven scam and if most of us avoided using it. I am sure they would cease operations at one point.
As for the part of trying to go the legal way I think you would be wasting money and time trying to take them to court as they operate in jurisdictions where they maybe out of reach from Law enforcers.
