I am definately no expert, when it comes to bitcoin, but I would say, that it is a litte too rash to say, that bitcoin has a "comeback". The fluctuation of the price of bitcoin in the last 3 months was insane! I would treat this topic very careful, because no one can really say, where the price will be tomorrow : D
