$250 coupons = $600 Z9 mini for batch 2 hmm.

The way I see it, if Zcash doesn't fork by Dec the $600 batch 2 Z9 mini will break even at least.
If it does fork, well that's good for my gpu farm.

The worst case scenario is the Z9 non-mini having way superior efficiency than the mini. The ProgPOW github did mention equihash ASICs have a potential 100x efficiency gain over gpu and the Z9 mini "only" has 10x efficiency. Link: https://github.com/ifdefelse/ProgPOW#equihash

Nothing risked, nothing gained. If things look good on July 14, I will be in for a few more $600 Z9 minis/doorstoppers.
