Interesting. I believe you or another author pointed out fake website traffic likely paid for to jack up the website rank(ie Alexa). One possibility is that they are also trying to spam Google's Pagerank algorithm to boost its results position(aka a Google bomb). There are many BTC services for this, and Bitconnect has a lot of BTC.

If the spamming service was native to asia that would likely increase the proportion from these countries. Also, the fact that their meetup/conference was held in Thailand further bolsters the case that Bitconnect is headquartered in south Asia.
