You're right though, the premined coins will all be going towards the promotion and growth of piCoin - we've already committed over 5% to people (from our giveaways, bounties, and promotion) and it's still launch day. We plan on giving away 25% in the first month or so through giveaways, bounties, and custom projects/bounties. We premined a very reasonable percentage and all of it is going back into the coin.
