"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.
They're arguably one of the major players in the mining industry at the moment so you might want to check your facts...
