Many sessions occur at SXSW, and one of the more intriguing sessions involved Cameron and Tyler Winklevoss.
The Winklevoss twins are the same twins referenced on "The Social Network" and are known for investing in emerging technologies.
An area they have a heavy investment in is Bitcoin, where they own about 1% of the total available Bitcoin in the world.
Bitcoin is a digital currency where encryption methods are used to regulate the creation of units of currency and verify the transfer of funds. All of these operations occur independently of any centralized bank.
Due to the encryption methods used, Bitcoin exchanges hide users from knowing each other and money simply exchanges hands. This has made Bitcoin the currency for digital black markets and other nefarious activities in the online world.
So, why are the Winklevoss twins invested so heavily in this digital currency?
"Right now we don't have a regulated licensed NASDAQ to buy Bitcoin in the United States," Cameron Winklevoss said. "80 percent of Bitcoin trading occurs in China, so America is basically sitting on the sideline of the Bitcoin economy."
To get America more involved in the Bitcoin market, the Winklevosses are creating a Bitcoin exchange site called Gemini.
"Gemini is a place to buy and sell Bitcoin," Tyler Winklevoss explained. "Easiest analog might be the NASDAQ, where you can buy and sell a share."
According to the Winklevosses, sites currently operating in the Bitcoin economy within the United States have no regulation and this is a major concern to users. As recently as just this week a Bitcoin exchange website saw its administrators run off with $12 million of people's money.
Last year, the Winklevoss, along with about 20 other investors who have been investigating Bitcoin, were subpoenaed by the New York Department of Financial Services.
The New York Department of Financial Services had been investigating the use, viability and other aspects of Bitcoin to begin regulating the digital currency.
"We have been working to help educate and help build our company to regulatory specs," Cameron Winklevoss said.
"Regulators are going to make the rules one way or the other. We've taken the approach of trying inform them as much as possible," Tyler Winklevoss said.
As the regulatory bodies become more involved, the Winklevoss see more legitimacy of the digital currency.
"Cash is going to be killed. Cash is going to look like vinyl," Tyler Wiklevoss said during the interview. "ACH Wire, credit cards and business bills on top of it, will die like dinosaurs. They will look like pay phones and long distance charges."
Even though Bitcoin continues to be veiled in controversy and difficult for regular people to access and use properly, the Winklevi see a world not just where physical cash is a relic of years gone by, but the world is connected through digital currencies, decentralized from any bank or government.
"It's really different way to think of the world," Tyler Winklevoss said. "What I read in textbooks and thought about the world a certain way, and it's like, 'Wait, it's all wrong.' It can be done completely differently."
