So, miner manufacturers are making their most efficient miners unavailable except as bare ICs with which to design and build one's own miner or available as a 'buy a share of my farm running these efficient ASICs.'

Like Bitmain. Many of us expected to buy an S5 post-Chinese New Year. _Not available_, _Sold_Out_. Now I'm wondering if it would be worth it at all! I'm at a state of cashing in my mined bitcoins to pay the electric bill. Profit is a slim margin helped by the non-burning of propane for heat this last winter. Now I'm wondering if payoff of a new miner, after deducting electric costs and taxes, can ever be achieved! Bitmain still offers C1's for sale but my C1 uses more power than I'd like.

I think the bigger risk is that they already have come up with the next best tech in mining and might already be mining on that.
By the time it hits the customer, it is too late.
