That would be wrong actually to think that it will bring this to zero.
Actually the every step that they take is well thought , people actually hire experts to give advice on it, at the same time I don't think they will be dumb enough to do things to be detrimental for the growth of Bitcoins.
The fact that the price is rising means Its already working , it might not be a bubble but actually something that works great for the future.
It's not a bubble , we are in green actually.
