Yeah, but chips already sold for about $0.35/GH/s in early June, so we're not achieving those prices anymore! But given the trouble with gen 3, we indeed may see gen 4 much earlier than initially planned. We could see sample chips in late October if this is true!
Source for the sales price of $0.35/G in early June, please?
1.9 CNY are about $0.31 at the current market rate. These chips were offered for delivery in mid/late June.
