Not until the company is fully liquated or you do something like delisted where you sell them your shares for nothing and can then claim the capital loss.
However if they do become of value you are no longer a shareholder so you will not be able to claim any future CG or dividends if these were to happen.
This isn't financial advice just informing of options to consider but speak to a financial expert for your personal situation.
