Around the 10 min mark you mention cyrptocurrencies are grossly overvalued... Cryptocurrencies in reality have zero value. What makes them valuable is acceptance in the market that creates demand along with a few other principles. Basic econ theory. Until more of the population (businesses and common folks like you and me) accepts the technology, the coins will continue to carry little to no value. Which is why it is important to minimize comments from the Warren Buffets of the world. His comments create fud that lead to a lessening of the value of the valueless "currency".
