“We believe bitcoin disrupts gold US:GCH8. We think it’s a better gold if you look at the properties of money. And what makes gold gold?

We think regardless of the price moves in the last few weeks, it’s still a very underappreciated asset.”

Neither Cameron nor his brother put a specific timeline on the prediction during the chat, but they did say they’re taking the 10-to-20 year view.

The Winklevoss twins were hailed as the first crypto billionaires, after riding the hype and creating an exchange that processes $300 million in daily transactions. The brothers are currently No. 4 on the Forbes list of wealthiest players in the space, behind the Binance CEO Changpeng Zhao.
