I expect these rigs to be no less than $500.00 USD each [including shipping]. That would be $50,000 minimum ...
You didn't hear from me, but try tripling the price - $1500 USD...
They argue:
"Based on recent Bitcoin and Litecoin price, a dual-mode SF100s revenue equals to a 2.8-3.2T pure Bitcoin miner, which makes it 0.3-0.34W/GHS power efficiency."Bitmain sells S5 batch 5 for about $0.31 USD per GH/s. Why should SFARDS price a more efficient product lower?
So I bet the price will be between $870 USD and $990 USD (exluding shipping).
