If you really want others to adopt mastercoin, you'd better encourage people to sell the coins. As a pre-mined coin, it's essential for the early adopters to be generous so that more people can have a chance to join. Otherwise, there will be no new comers and the coin will be doomed. It's better to have 1M of coins with price 1 BTC later each than have 10M of valueless coins.
Everyone says that pre-mined is less democratic, but I haven't seen any proof to back up that argument. Following how PTS was mined in less than a week to a level of difficulty where even high-end servers are almost useless, I'm leaning towards MSC model. Early adopters always have a huge advantage.
