In order to understand Bitcoin, you need at least 4 certain personality traits.

- Average IQ (you can’t be a complete idiot)

- Understanding the value of high-time preference (long term thinking, delaying gratification for the future)

- Risk averse (knowing that there is a small chance you lose all of your money, but will pay off huge if you’re right)

- Open minded (willing to let new ideas change your perception of the world)

Those 4 qualities are absolutely necessary. And I’d guess less than 50% of people in the U.S posses all 4.
