Anything is possible in this crypto realm. The price increase might be temporary or it might also continue for a long time, and no one can tell. IT all depends on the greed and faith of the people supporting it, whichever of the two is more dominant. No matter how good a news about bitcoin is, if the people will not ride it, it won't do any good for it. And sad to say, many people are just riding the wave of the market. Thus, there is truly a need for a regulatory body if we really want to see bitcoin's value grows continually.
