Alpha has been selling/buying since 2009 & is still here with his partner Longview, so i rest my case lol. Additionally, have not yet located anything in filings indicating that he was issued all Series C so contrary to your claim, doesn't look like he was b/c as per the filings, he would/should have been listed as an owner before last 10K filing & believe his13G filing combined his commons with the 78 Series C - just like Brausers' 13G filing combined his commons with warrants.
