Does Jihan wait for bribes or what? He knows he's got power now and he has the option to make lots of money. Maybe he suppresses the market for a long time, and finally announce that BU won't be realized => BTC to moon
This is surely possible, but even more likely is that he just does not want to admit he was wrong
For a decentralized coin, there sure is a lot of power in the hands of petty people sometimes. The good thing to remember is that behavior like this will ensure a lot of people will start bringing people like that down.
