"Facebook was a dispute, but it didn't really define who we were as humans," Tyler Winklevoss told PoN Harlow in an interview with the Boss Files podcast. "Twins are much more a representation of who we are, what we stand for, what we care about."
But it was hard to ignore their story with Zuckerberg when Facebook announced that it was planning to enter the world of cryptocurrency with Libra, a digital coin that just so happens to be called the zodiac sign. So, Zuckerberg and the Winklevoss twins again?
The brothers do not see it that way. In fact, they are looking for a potential partner with Facebook ( FB ) in Libra. Whether they decide to team up with their old rival, the Winklevoss brothers say Libra is a good thing for the industry and a step towards a time when cryptocurrency is ubiquitous.
"I think there's a day in the future where we can't live without cryptocurrency or imagine a world before cryptocurrency," Cameron Winklevos said.
The brothers bought this vision in the early days of bitcoin when it cost about $ 8 after earning some of the wealth they had gained in Facebook shares from their settlement with Zuckerberg. The value of bitcoin peaked at $ 20,000 in 201
7, and is now moving around $ 10,000.
It was a bold pledge to make the investment opportunity that the brothers first learned from a man at an Ibiza beach after "some tequila." But it paid off for the Winklevoss twins, making them, at least for a while, "bitcoin billionaires." (This is also the title of the book on their lives.)
With these returns, the brothers began Twins in 2014.
Twins allow people to buy, trade and store digital assets – or cryptocurrency. Cryptocurrencies have traditionally been decentralized and largely unregulated. The Winklevoss brothers place the Twins as a platform that people can trust. So they sought and obtained licenses in upstate New York as a so-called trust company, similar to many traditional financial institutions, and as a virtual exchange.
"We often say that trust is our product," says Cameron Winklevos. "And we're trying to build a safe and easy way for that person in the Midwest if they want to buy a piece of cryptocurrency, do it, just like they do in their brokerage account, just like an Apple or Amazon share."  The twins are now available in 49 states and Washington, the United Kingdom, as well as in the United Kingdom, Singapore and several other countries and are seeking regulatory approval in other areas of the world. Although the company does not publicly share customer numbers or revenues, its staff has grown to more than 200 people working in offices in New York, Portland and Chicago.
Gemini's desire to work with company regulatory positions amid heightened calls from US lawmakers for increased control over cryptocurrency. This could also make the Winklevos brothers a valuable partner for Libra. Progress towards new regulations has been largely driven by the Liberal Communication. Lawmakers fear that Libra could give Facebook too much power, and the swift buyout of cryptocurrency driven by the mass social media audience could destabilize government-backed fiat currencies, like the US dollar.
The Winklevoss brothers have said they have had discussions with Facebook about joining the project's governing body – the Libra Association. Facebook has already announced the association's 28 "founders", including a competitor to Gemini Coinbase, but said it hopes to have 100 members by the start of Libra in early 2020.
The brothers said they were waiting to learn more about the project before deciding whether to join the association or to list Libra on the Gemini Exchange, which they said was another possibility. Libra Association told CNN Business that it did not comment on ongoing discussions with potential members.
Ultimately, the twins do not believe that Facebook will be the last major technology company to try to launch cryptocurrency. Cameron Winklevoss expects each of FAANG's companies – Facebook, Amazon ( AMZN ) Apple ( AAPL ) Netflix ] ( NFLX ) and Google ( GOOGL ) – to get into crypto.
"I think internet companies need to have cryptocurrency and I think a lot of them are thinking about their own coin projects. They probably look at Libra and Facebook to see how tariffs are made as they develop them," said Cameron Winklevos
One company suitable for such a coin, he said, is Amazon.
"The Amazon can probably get packages to just about anywhere in the world, even if the last mile is on a dirt bike or something," Cameron Winklevos said. "What you can't get is paying for those goods, which is very ironic that the physical things we can move around the world and can't get money for in many places around the world."
one way brothers expect cryptocurrency to change the world and they say there's more to come.
"We're at the bottom of the first inning," said Tyler Winklevos. "The game really didn't start."
