Holders (not the team) gets a 1/3 vote counted per EXP held, and the Advisor Board nominated and voted in by the team and the holders gets a 1/3 vote.
Is it possible to distinguish between core team premined coins (10% of reserve) and mined coins?
I believe by address, yes, but Dan Conway should have more information explaining exactly how that works later. Obviously anyone could buy Expanse and vote with their expanse, but the initial reserve for the team will be publicly available with addresses. We will definitely be holding most and only selling small amounts as needed. The design is such that we believe we can increase the value over time for traders and miners, and of course for the team.
