At $6.50 per GH/s as the Minimum bid just for the chip? You would have to be a complete and utter moron to bid on these.
Yea ... add to that the assembly and component costs ...
Also, who would bid on this based on a current announcement? You'd have to rush the PCB and the components based on their design on the GITHUB and *PRAY* that it works. There's no:
1) Sample chips
2) Examples of verified design based on GITHUB docs
Chips got refunded.
The refund was only as a precaution to avoid litigation. It can't avoid litigation due to breach of contract if someone wants to litigate ... more than likely they got legal counsel for this decision. The chip refunds and delays are crap. Avalon has not provided sufficient compensation for the refunds.
