Only a year later, in 2013, the twins revealed to the New York Times that they owned $11 million worth of the currency, mostly purchased when it cost about $10 per coin.
By 2013, a single Bitcoin was worth $120. And also at the time, many more people were skeptical of the currency, believing it to be the backbone of the black market more than anything else. But the twins were believers.
“People say it’s a Ponzi scheme, it’s a bubble,” Cameron told the Times. “People really don’t want to take it seriously. At some point that narrative will shift to ‘virtual currencies are here to stay.’ We’re in the early days.”
Fast forward to the end of 2017, the year Bitcoin became mainstream and incredibly valuable. By the start of 2018, one Bitcoin was worth about $14,000 — making the Winklevoss twins Bitcoin billionaires.
In the first months of 2018, it slid back to $6,000 to $7,000 a coin — while it was precipitous fall, it was still an impressive return on their investment.
