Seems like a pretty solid offering you are keeping costs low and providing a high amount of shareholder protection.
I do wonder about the somewhat high buy-in level. Why not 1,000,000 @ 0.065? Do you already have a split in mind?
We felt that 10GH/share for 0.65
BTC would be an affordable number to invest in mining. If liquidity ever becomes a problem we can file a motion for a split.
