Youengine don't fail, price later pump back and some hunters that held were able to sell at a very fair price, so youengine team did well to pump the price after bounty distribution
Yes, if the team still really cares about the Youengine project, then there is a high probability that their token price will experience a good pump in the market, but if the team doesn't care about the project, then don't expect the price pump to happen to their token, and even them also could die in the near future.
