I see people sayin that Gold and Silver are dead and being manipulated, but regardless, they will always have value, and as mentioned in the video, are a good hedge.
I don't have a lot of cash to invest, and most of it is in various cryptocurrencies, but I also have something in Gold and Silver.
Gold and Silver have been used as currency, or at least a store of value, for thousands of years, and I doubt that'll change.
