These questions make a lot of sense. The way I see it is that there will be pay-to-play services, hopefully thousands of them using the Steem blockchain and STEEM and SBD as means of payment. This will create demand for STEEM and SBD and drive up the price of Steem Power. Anyone accumulating Steem Power at this stage is like an early stage investor in a project that has the technical capability to be the backbone of all that traffic.
