"Regarding variables, it’s very clear there is huge suspicion about paper money around the world. This suspicion is gathering steam. Governments are printing huge amounts of money. This has always led to higher prices. Maybe I am wrong and it’s different this time. But I doubt it.
Additionally, no new large gold mines have been opened in decades. Some of those mines are over 100-years old. They are all depleting. On the other hand, central banks have huge Gold reserves above ground — and they are less interested in selling than in the past.
If you adjust Gold for inflation and go back to its former all-time high in 1980, Gold should be over $2,000 an ounce right now if you want to say it’s reaching new inflation adjusted all-time highs. That does not mean Gold has to get back to a true all-time high. Nothing has to. However, I suspect that given all the money printing in the world, we will see much higher prices for hard assets.
Despite Gold’s potential, I think I will make more money in other commodities such as silver, cotton, or coffee — all of which are terribly depressed."
