So the #1 question I have for you is, as the chances of being awarded blocks goes down. Why on earth is anyone going to want to play the silly game invented by you people who happened to stumble upon easy BTC first?
After all, Knightmb has 10% of all the exiting BTC. He probably bought and generated them for less than $1,000 at the time. If I decide to trade some commodity worth $10,000 I would likely end up with less than half of his stash.
He put in $1,000 and I put in $10,000 a couple of months later. He is more than twice as rich as me. If someone tries to trade $100,000 worth of commodities for BTC a few months after me, is he going to be half as rich as me and a quarter as rich as knightmb?
That seems like a poor game for him to play.
Why does one cares about the relative wealth of another individuals versus our own, especially in a system where people can mutually gain from exchanges? If anything, one should be concerned about one's own absolute wealth over time, not one's relative wealth to another.
