Well, look like opening guessed are betting pretty high. I guess betting for negative isin't going to take us anywhere for a while. I was hoping this wouldn't happen before S7 actually got out.
It is likely S7's are being made now. I would guess they first go into bitmain's data centers in places were they sold S5 used units. Then eventually the S7's make it to public hands.
But I think internal will be first priority for them.
