It's a pre-revenue company. A scam insinuates some sort of fraud is at play. Maybe there's other issues and maybe there aren't. I don't agree with the permabulls that speak as if there is no way this thing could fall flat on it's face but I am quite content investing my money here for the chance at outsized returns.
If you had any proof management was making material misstatements of fact you'd be filing reports with the SEC and sitting back and waiting for the 10-30% finders fee to show up in your bank account.
