In 2014 he said Bitcoin is better than currency and praise Bitcoin as it is ” exciting because it shows how cheap (transactions) can be.”
But times have changed and now he thinks that Bitcoin and other cryptocurrencies has caused direct deaths.
“The main feature of cryptocurrencies is their anonymity. I don’t think this is a good thing,” he said. “The government’s ability to find money laundering and tax evasion and terrorist funding is a good thing. Right now cryptocurrencies are used for buying fentanyl and other drugs so it is a rare technology that has caused deaths in a fairly direct way.”
