Looking at your shop, going to spend soem money. Are these real or a scam?
Hex8A1 is not out yet. Who knows if the chips will ever arrive, but their videos look pretty convincing, their estimate was 34GH/s per chip.
I can vouch the Hex16B is real, I have one, awaiting delivery of another 5 before the end of December.
