I'm pretty sure all of the revolutionary advancements of our lifetime were not built on greed. You name it, probably wasn't greed. Facebook, Internet, Google, whatever. These were all exercises in intelligence and providing utility. Solving a problem, not looking for a cash cow. The adoption and subsequent profitability came after and probably was not a forethought.

Edit: and in that batch, I include bitcoin. "satoshi" didn't even want WikiLeaks to accept BTC because it's still in beta, but if he were greedy he would surely implore them to do so. He/They/whatever, probably would not be happy with how Bitcoin has been going.

But you're right, I do believe a huge, HUGE majority of new "adopters" are here just for the quick profit. Couldn't agree more.
