I think a lot of the price has to do with Alibaba. There might be some concern with the technical issues that have formed over the years for Bitcoin. I really do not know, but I am starting to diversify with new investments. I do hope Bitcoin jumps back up to 600 here sooner than later.
not alibaba..
its takes days to get fiat out of PHP exchanges. and then more days to move funds into share trading platforms. thus anyone involved in alibaba would have exited bitcoin 2 weeks ago, not now as its too late to get in at the launch
