I have been watching this forum from the outside for some time, and i feel it’s time to add a comment.

Those numbers on miners apparently sold, or up for sale, are in my opinion unrealistic. It would take a huge undertaking, production wise, to manufacture these units, not to speak of getting the chips, where Bitmain are in competition with all other manufacturers who use any kind of chips, to get a slot of production capacity. To my knowledge there are only 4 plants in the world that can manufacture 16 nanometer  technology, and they are constantly booked up.

Next, if Bitmain really should sell all those numbers of miners, I would not really worry about it. There will always be a balance between earnings and cost, and as soon as diff. rate increases so much that earnings go below cost, the first miners will be shut down. They will continue to shut down, in numbers, as diff. raise, until only those with very low (electricity ) cost are still mining.

So there will be a bottom in the marked, but only those who are in control of their cost will survive.
