No demo, refusing to send a board (that will be shiped back to the company after tests + videos) to a very highly trusted and estimed member, I don't care what the company is, I smell red flags and scam. Period.
Why would we send a board to someone with no experience mining with FPGA or Verilog experience? You need to understand what this is before making accusations. If you don't want to purchase then fine, no-one is forcing you to.
Why would You like to collect money from someone with no experience mining with FPGA or Verilog experience?
