You don't have to be a gold bug to believe that ;)
I generally agree with you; however, gold will eventually double (don't know when) just to keep up with monetary expansion. Yes, Bitcoin has advantages but all the rich own some gold and they won't let it go to zero, no more than their worthless modern art.
Gold is a commodity. It doesn't go bad like soybeans. They can only mine a certain amount. Eventually it will come back as all things do, even wide bottom blue jeans.
In other words, you're right. But it doesn't matter. It never has with precious metals throughout all of history.
