It's such a tremendous disservice as financial commentator to scare people away from cryptocurrency. Indeed, even if the chance of an extreme outcome on the upside is low, it is still a good bet. A prime example of Taleb's asymmetrical bet: a bet with a known maximum loss and infinite reward on the upside.

For people concerned about the financial system and the debt building up, I see no reason why gold should be the only hedge. A small stake in cryptocurrencies besides gold would not be a bad strategy.
