I’d also add that buffet hates the concept of gold. Aside from a socially acceptable form of modern middle class gambling in my opinion the primary use case of crypto currency is a store of value.
Aside from the amount of time it’s been in existence what is the difference between gold and something like bitcoin? Only ~4 of gold is used for industrial purposes the remainder is used for jewelery and stuff like bullion. Basically stores of value. It trades at a premium above its cost to extract, store and transport.
