A simpler calculation: there are approximately 9 million coins remaining to be mined. 10% of that, divided by 400,000 shares gives you 2.25 BTC per share. So things like hardware sales, transaction fees, and optimism that we'll have more than 10% share of the network had darn well better make up for the long wait to earn those 2.25 BTC. That might be reasonable. Any thoughts? (sure beats estimates based on infinity)
