"A chip in every toaster" people?
There are two ways of making money with bitcoin mining. One is to mine (risky, often disastrously unprofitable), the other is selling dreams to starry-eyed bitcoiners (easy, fun, works 99% of the time, no tech/con experience required).
Don't think 21inc is planning to do much mining.
The key is to hire a talented and proven shill. If only there were someone like that around here...
