mmm. Let me think about it. Let's say I want to produce 5,000 SP31 in December (just an example, not a real batch number)
I'll need a 15MW farm.
Ok, I'm convinced we'll build it. But if we're building 15MW, why not build 150MW?
Why do I need to sell the miners?
I'll do more money by mining myself over few months.
I'm cynical here myself.
Buying from any manufacturer with farm just hastened the centalrization of the network.
BitFury, KNC, Cointerra, Bitmaintech.
If one of those will think it got technology and cost advantage they'll stop selling and do only self mining. They're using hardware sell as a mean towards increasing their own farm percentage in the total network hash-rate.
Buying from any of the above is scrarifying the long term for short term gain.
