1 mil is pretty much pre-mined. What if these pre-mined dumped to the market?
Devs are not interested to dump. Premine is for bounties, rewards, listings end so on. It is more likely that one of the members of the community, having received a large income from the masternodes, will dump the coin. It is necessary for the community to understand that it is in the interests of everyone to keep the price high.
