I think the insights on the multipool's effects on the market are a bit flawed. As far as the miners go, they're getting a constant stream of BC that they will in turn sell back into the market. Sure, the pool is buying to supply the miners, but the net could easily be no market movement at all assuming the miners dump their coins back (they almost always do).
But it is an interesting experiment.
Yes, I thought about that as well, but concluded that the group of people who would mine on the multipool would tend to be a very specific subset of the mining population. Namely, BC holders. It resembles a share buyback program of a publicly traded corporation in some respects. Mine-and-dump players would likely be fishing in other waters, and rightly so. That is my expectation. But as you say, it's an experiment. We'll know by the results.
I don't think it is this simple, If the multipool is fast and dynamic. We will 'suck' the cream off of other alts that are on the rise. I don't see any real-world way for it become a zero-net game for BC really.
The only way I could see the Multi-pool not bringing game-changing price advances is:
100% of multipool BC is dumped immediately back. (even 99% dump is a net-gain) (though even this would still be volume and activity which is good!)
No one mines in the multi-pool. Not even 1Mhs. (yeah right, its going to get hundreds of Mhs at day one)
All other alts or crypto dies immediate...
