@otemzi It sounds like you may have a way to get more information? If you discover anything useful, please share it with us all!
As I mentioned above, part of the movement is due to vanity buyers, the rest is investors anticipating the future. That's why Amazon went from zero to $200 ten years before it made its first profit.
This should probably be the major reason, when new investors come into an organization, we get increase and improvements of that organization and also looking at vanity buyers as you mentioned, probably buying and exchanging steem to other crypto coin, reason for this is that looking at the price tag for both steem and steemdollar, the increase affects steem quite a lot afterall steem was supposed to be the superior.
Be that as it may if I do get any more info would be sure to bounce back and update
