I cannot afford to buy any shares when I'm under by 90% after partaking in the 26c capital raise a couple of years ago, my investment now is jus cents in the dollar, and a long way from the heady days of being in the mid-high 30's back in 2021. I am a holder, as i believe it's time in the market rather than timing in the market, but my sick portfolio of ADO, CNJ, EFE, CDT, CCZ and DOC might rate one step higher than a session on a poker machine. Have no gains to offset, and the biggest rort is that the tax office doesn't allow you to claim these losses against my income, even though it was my income which furnished the money to buy the shares is already taxed anyway. Complete horse-arse to be frank.
