As I know Japanese start accepting bitcoin on early April by their goverment so that cause bitcoin demand getting higher recently.
Bitcoin value is adjusting their demand. But in other side, I'm fear what if another whale trader/investor are behind the scene of this bitcoin enhancement which will cause dump at the end ...
that would have to be one monster of a whale. i think bitcoin is moving out of the phase where one group or entity can play with it that much, especially when there's genuine demand from all over the world. their stash would get eaten up.
