The real answer to this question is the supply that keeps being released into the market. If you've been paying attention, you can see that over the last month the number of SPS in circulation has gone up by like 30M. If you look at the market cap chart you'll see little spikes in market cap with no real volume to drive the price up. That's where the supply is being released. Then a portion or all of that supply is sold into the market and the price goes down.
While the factors you talk about are indeed factors, the biggest driver is the supply. Not sure how long this will keep dripping into the market but...until it ends (or at least pauses for a couple months), the price isn't going anywhere.
I can't remember the exact numbers but I seem to recall back in the fall there being less than 500M. I actually think it might have been considerably less than that even. Probably under 400M. Now it's 640M. That's a LOT of supply to eat without anyone selling.
Just keep watching that number. Someone should ask on the AMA when it's going to stop. Like I said, until it does, the price ain't moving.
