Yes, we need pools. Source code will be available within 12 hours from now.

Source code will be released after launch later today and pools will be created after that.
Official pool will be launched after 1 week.

200 is the max. Unsold coins in the 2 million (for masternodes) out of the 3.5 million premine will be used for promotions including bounties. There will be no dumping of coins by the dev team.
