Must be a lot of ATM transactions or institutes buying in to get this kind of volume. 

Surely it's not just youtube traders?

With 97,000 viewers, it would only take purchaes of a little over 100 shares per viewer to cover the 11mm shares that have traded in the past 3 days.   Not that this happened, but its much more plausible, given timing of the video release and the massive demand increase, that retail is responsible for the lions share of buying and not institutional. 

Not kidding, my name's not Shirley!
