The price may be increasing due to the upcoming Peerplays snapshot. This will take place over a period of weeks at the beginning of September.
An interesting decision was made for the sharedrop which we may be seeing play out in the market price. Namely, that known exchanges will not be included in the share drop. This means that if you own BTS and would like your portion of the Peerplays share drop, you have to move those coins off the exchanges before the sharedrop begins.
Thus the price increase may be due to the diminishing supply of BTS on the exchanges as people move their BTS in anticipation of the shapshot.
It has been speculated several times on this forum that keeping BTS off the exchanges might boost the price. There was even a proposal by
@tonyk which would take BTS off the exchanges completely. But i don't remember the details.
It is a very interesting experiment we are seeing play out. And if in fact this is causing the price increase, a very lucrative business model to drive the BTS price would be to propose dividend payments or sharedrops to BTS holders which take place at random (unforeseeable) times in the future, and exclude the exchanges.
