Hold on, hold on... If the price does spike early due to limited supply, that's what will trigger people who already generate solar to start submitting their claims in earnest which will start adding to the supply (coins in circulation). That will keep the price in check from going too high in the short term because many of those claimants will be more inclined to sell or be inclined to accept SLR as payment and get transactions under way.
So exciting to think about all of this! I think we are about to witness something special and unique with SolarCoin.

Many books will be written about it in the future. I might start taking notes now... LOL
