I understand that it is a way to save your gold only, that is, if I have my stash in 1b and my gold in 1b, I can buy the gold bar in 1b and I can resell it in 1b and that way my bank is emptied and I can continue farming good gold idea, the truth is that it is like an active good, just as gold and money happen in real life, but not on paper, rather if you sell it, it becomes real money and you have your investment behind you.
