It is time to get the idea that gold will be integrated in some way to Blockchain technology, I like the idea, of course it is my particular way of thinking, in this article it is said that you can buy Gold through BitPay:
BitPay Integration Lets Users Buy Gold With Cryptocurrency, currently after Conflict that occurred between the US and Iran has increased interest in acquiring both.
I think it is positive, the movement of money towards assets such as gold that are safe and towards Bitcoin, which in the view of many economists is not completely safe due to volatility, but that many people in the world are adopting as a refuge of value ignoring the advice of those economists.
