His game is identifying undervalued assets. If you're not confident you know how to value the asset you can't identify undervalued ones. I guess the point I was getting at was valuing a tech stock and valuing a crypto have little to do with one another. One is a business (which might be used as a speculative vehicle) while the other is a speculative vehicle. EDIT: More specifically anything with as much hype as crypto (and tech to a lesser extent) is not really in the value investing camp in which Buffet is trading. Avoiding them entirely is a very useful heuristic for him.
