Investors are buying the stock, as evidenced by the volume of shares being traded. If you are wondering why the volume is not significantly higher, there are several reasons. First, the number of outstanding shares is relatively very small. Second, it is still a relatively unknown stock. Third, institutions are not buying because of the OTC status of the stock.
The recent significant decrease in stock price was mostly due to the couple of institutions, that did own stock, selling their relatively large number of shares of the total outstanding shares.
