I am guessing there are probably lots of laws I am missing here ;(
The buy/sell spread will be a problem though for sure! I would have the extra costs of shipping, bank fees, and a little profit to make it worth while. It might be possible on a 1oz gold but I think the cost would be too high for silver

I am more interested in the gold anyway. Have a look at this site :-

www.silverstackers.com

There are a lot of Australian stackers there trading the secondary gold/silver market there and some of them accept crypto. What you're suggesting has been done before, just maybe not as a business.
