Everyone's getting very defensive/protective about their beloved Bitcoin.
How about addressing the OP's point with a bit of logic?
FACT: MMMGlobal users must use Bitcoin in order to participate.
FACT: There are hundreds of thousands of them, if not millions, worldwide.
FACT: In the main, they appear to have no previous history of interest in Bitcoin.
FACT: The popularity of MMMGlobal has increased considerably since October 15.
FACT: The Bitcoin price has increased considerably since October 15.
I'm not claiming to have all the answers, but the timeline suggests that the November spike could have been Chinese MMMGlobal inspired and the drop correlating with MMMChina freezing and bitcoin being pulled out of Global as well.
The continuation of the rise after the pullback could be inspired by the take up of Global in other countries, mainly Asia and South Africa.
