Entrepreneurs Cameron and Tyler Winklevoss, co-founders of Gemini which is a virtual bitcoin exchange, speaking to Bloomberg during SALT conference in Las Vegas said that cryptocurrency is the way of the future.

When bitcoin was introduced into the market, many were doubtful about the new form of digital currency because of security reasons and records of criminal activities. Tyler Winklevoss stated that, “Bitcoin is acting like a mature asset today and there’s a lot of liquidity and a lot of licensed operators now like Gemini.”

The twin brothers believe cryptocurrencies will be the new norm in the future predicting that the U.S. dollar will be government-controlled.

Gemini previously won the approval from the New York Department of Financial Services to begin trading Ether, a cryptocurrency similar to bitcoin. After the approval, Gemini is expanding the kinds of cryptocurrency that can trade on its platform and hopes to become “Nasdaq” for Bitcoin buying and selling.

Talking to FOX Business Network, Cameron said that, “Ether is the token of the Ethereum network, which is focused on disrupting contract law. Trading began on Monday and it’s our second cryptocurrency to add to Gemini.”

Further, Tyler said that, “You’ll be using digital currency and I think really what will happen is you’ll use a combination of bitcoin, ether, your devices, the ‘Internet of Things’.“ With lots of devices coming online, the twins predict that use of cryptographic tokens will increase and fiat currencies will become digital.
