1) Free market capitalism is the best path to prosperity, and you can trust different vendors and choose different services. We're not for everybody.
2) If we sell less than 100 Shares we'll put it to a vote--refund or purchase smaller units, like a few SC Singles.
3) The extra money goes into maintenance and administrative fees. For example we'll have additional insurance for the MiniRig, and we'll have to pay a Use Tax in Minnesota for purchase of the MiniRig. Also we're paying for 2 years of colocation at our top notch data center. Everybody wants redundant power, redundant internet, 99.999999 uptime, etc.. those things don't come cheaply. After 2 years, it's nowhere near $15,000.
4) That's sort of insulting to Bitcoiners we feel that there should be a long term plan, and trading shares invites scams.
5) We feel that the MiniRig will be profitable for 2 years, and after 2 years it wouldn't be profitable. It's really that simple.
6) The goal is to double everybody's money.
