In fact, we can actually prove they did spend some money to develop these chips (cf Howard wang and TheSeven) and they could easily argue that development is ongoing. Missing deadlines and being or hiring incompetent people is not a crime. Selling unregistered securities however, is. As is making materially incorrect statements in your prospectus. But those are SEC issues.
How would you prove that? The IPO was done by "sam", no one knows who he is or if he even exists. How do you prove Fabrizio is even involved? Dont get me wrong, I have no doubt he is involved, as is Alberto, but IMO you will not be able to prove this without getting the SEC involved and subpoena BTCT. Those documents that were published dont prove a damn thing, I dont even see Fabrizio's signature on there. Anyone could produce those.
Fabriazio admitted himself he has signed a contract, and Howard met him face to face. So he definitely is involved. He has to find a lawyer, not us, to defence for him.
Whether to report to SEC or police does not matter. Why not just report to both?
