Gold isn't easy to use in commerce since it's hard to pay the correct amount with gold. A solution could be to store the gold in a vault and transfer the ownership of gold pieces from the payer to the payee, but then you have to trust a third party holding the gold. An other problem with gold is counterfeits with tungsten. A bitcoin is divisible up to 8 decimal places so it's never a problem paying the correct amount. You don't have to trust a third party when using bitcoins and bitcoins can't be counterfeited.
you must expand your holdings by using your profits to produce more profits… because, if you don’t have the right “stock” at the right prices, then clearly, you will never profit
