OP, do you have any tech spec from your hardware design?
At least also provide us your spec, so we can really judge the performance of your fpga miner. Is it really worth to invest or not.
I myself play around already with legit and top of the line fpga development board, therefore able to give you hints at least on the performance wise based on your fpga chips and algorithm.
No answer is an answer.
I think this FPGA miner is like SoftRAM / ACORN ... probably SCAM .
Would you care to elaborate on why you are lumping Acorn in with scams?
Acorn is a very real product with a massive amount of work behind it...
