I wouldnt say its just like that, we got people watching like hawks looking for entry and when to catch a tide for ride up and so on.  BTC is famous for its speculators of course.     The scenario I see now is of a negative trend but also exhaustion and the end of that trend.  People typically get gloomy at their most extreme on the tail end of this negative trend but the important note is we already fell, its too late to be gloomy now the smarter thing is keen eyes looking for a change in the prevailing wind.

Doesnt have to happen but my view of this 'sudden rise' is people carefully noting and entering for a possible rise.   It takes more then one factor but for a global market its complicated to see all points of views in all currencies.  In some very troubled currency like Turkish Lira for example they already are grateful to hold some BTC I think
