If 30,000 BTC is raised, it will be roughly $30 million raised. That sounds the way to enrich the founders. I don't think you need $30 million to finish the remaining development. Colorcoin and Mastercoin didn't require that much money.
On top of that there is no cap on the amount of Ether being produced, as it be 40% forever.
Can you please let me know how its going to keep its value, when there will be more in circulation every year and for ever.
