I'm probably not 100% understanding how this works, but is it true that if the rate of people investing outpaces the amount gambled, the returns will dilute? If so, would it make sense to have some sort of on-the-fly tracking/scaling of a total allowable house investment base on a windowed rate of house gain? Something to keep a fix on the estimated rate of return. Just like there's a max-bet determined by the pool size, this would be keeping the other side of the coin intact.
