Typical Buffet move to invest in a gold mining company rather than gold itself. He's in the business of buying shares of value producing companies rather than rare commodities that are meant to be bought and hold. Also if everyone's digging for gold, what better move is there than to start selling shovels?

As far as Bitcoin is concerned, I doubt we'll ever see a move in this direction in Buffet's lifetime. First of all it's not his investment style (ie. it's a rare commodity rather than a company) and secondly he stated that he doesn't understand Bitcoin and is not willing to invest in something that he doesn't fully understand. Which I can only respect since honestly it is a kind of level headedness that is often missing in crypto.
