Since two days ago Z9 Mini is -Sold Out- so...
What's the next step of Bitmain?
Release a new batch of 'Z9 Mini' cheapest than 850$?
New batch with the same price?
Not sale 'Z9 mini' again?
Equihash miners went up in performance so fast, it probably doesn't make sense to sell the Mini again. I bet they switch to only selling the big Z9 (against the A9 ZMaster and others) and competing on hashrate+shipping-volume (where Bitmain can throw miners in the mail for buyers faster than anyone else).
Well,
Looks like they have "thousand" of Z9 Mini in other warehouse because now is in
STOCK again...
Let's see what's happen in the future, I don't think they will devalue the price of 'Z9 Big' if they still having Minis for sale at 850$.
Once they sold out all the Minis, maybe they sell the Z9 it cheapest than now.
