The answer to your question @swelker101 it's because they're going to buy tokens at the same price offered to the rest of people: 1 STEEM = 1 SPHERE.
So, if they buy tokens, why they wouldn't also enjoy the benefits of being another investor more making bigger the project?
We're putting our own money to make it bigger and therefore a better place to everyone, since the bigger the project the better the benefits for all the investors.
