EDIT: Just went back to look and peek Google Trends interest in Bitcoin happens prior to peek Bitcoin price so public interest leads Bitcoin price as I suggest. Trends crash before the price does.
Do you really not think the general population's interest in bitcoin has any effect on the price?
This will go on just like previously until the bubble pops again.
I believe the public interest is sparked by the price - which is perhaps later adding additional additional price hikes sure - but the correlation is not public interest to price; I think it's the opposite, price to public interest.
Price drops - so will public interest.
