Guys I'm wondering why BTC is moving this fast to up? With logic there should be a huge amount of money flew into BTC market but I don't see any reason to make this happen.
Is there any economic reasons about this massive flying to up? What are your opinions about this happenings?

Your post is about almost a month ago, and we have the observation that Bitcoin moves fast by the month of December. Just like dollar its value is not stable especially December is a peak season money uses from time and time. And when it uses the flow chart of money will be increases too. Just like here at Bitcoin, peak season is one of the cause for its become popular.
