Rarely would the SEC move this quickly - I have seen then take up to 18 months for a suspension and other times such as with CYNK both FINRA and the SEC suspended them within weeks.
But on every OTC scam - there are always shareholders that post about how the SEC loves their company and would never suspend it.
So we shall see - but I guarantee the SEC doesn't love this nasty shell - too many Red flags associated with GRCU.
