Good question... Though likely the answer is pretty mundane: It's probably something they keep being asked about in interviews, and they feel some obligation to dampen the hype on cryptcurrency- Also, there's a "survivorship bias" issue, in that both guys got very successful using business strategies involving an unrelated domain, so of course they would say "If you want to build wealth, maybe instead focus on these other asset classes that worked really well for me."
