is AC8 deflating to zero?

So it's been over two years since AC8 listed The restricted stock got released from escrow 4/2/19 Then there was a massive dumping of AC8 stock, which to account for the significant fall in price would have had to be from a large stock holder (likely a director). As a shareholder, I'm concerned that my stock will dwindle down to zero. (In fact I'm confident it will now, but secretly hoping that someone will see value in buying the company out?) However, looking at their December quarterly accounts, they haven't made any money at all? They appear to have made no progress in two years and most of their news flashes about drug discovery and creating pharmaceutical grade products appear to not be validated by searches of the online databases at the TGA. Should I be worried and should I be selling out?
