I think it is definitely worth noting that the last spike in price coincided with the
highest weekly exchange volume in bitcoin history... double the previous record... mainly China. Over 6 million coins were traded (almost half of the entire coins in circulation) compared to the previous record of just over 3 million in November 2013. That is extremely bullish.
