well if you read my post carefully you could see I suggest you can sell your gold to FIAT
anyway, in some countries this method, while more troublesome, I agree, allows you legally not to pay capital gain taxes, because buying physical goin is tax free and selling you gold to fiat involves no capital gain tax (in some countries)
Do you have any source for this information? As i understand it, selling crypto to gold is considered a taxable event and CGT would become liable. Its possible that if you do this outside your home country then import the gold, it may be a legal avoidance method.
