I'm not sure where you are getting their updated float, but depending on where you look, it differs. OTCM has it at 66.98M, MarketWatch 76.24M, and Moomoo 73.64M. As they keep issuing more unrestricted shares, the float goes up and as long as the daily volume stays low, the float will increase exponentially. No one's buying! Keep in mind that Market Makers will buy on the open market for inventory purposes, but the price will never go up.
Their last 10Q in January shows 10s of millions of warrants issued and outstanding. That does't necessarily mean that the companies that exercised the warrants are dumping them on the open market. The sheer fact that these shares were created and issued dilutes the stock (algorithm controlled), but once they dump them on the open market, that creates a corresponding downward pressure. I've seen firsthand with this stock when all the shares on the 'ask' are bought up, the share price and bid just goes down.
A stock's float refers to the number of shares available for the general public to buy and sell in the open market. It is calculated by taking total shares outstanding and subtracting closely held, restricted shares (insider-held or institutional). Float indicates a stock’s liquidity, with lower floats often creating higher volatility.
