The founders of the Gemini exchange, brothers Tyler and Cameron Winklevoss, are “determined to make Bitcoin-ETF a reality.” They stated this during the Ask Me Anything session on Reddit.
According to Winklevoss, in the long run, Bitcoin will be able to hold its position as a means of preserving value, and its capitalization will be able to overcome the $ 7 trillion mark.
Our thesis around bitcoin's upside remains unchanged. We believe bitcoin is better at being gold than gold. If we're right, then over time the market cap of bitcoin will surpass the ~7trillion dollar market cap of gold.

In turn, Cameron Winkloss said that cryptocurrencies still need fiat money, but in the future, all assets are likely to go digital.
In addition, the brothers expressed confidence that blockchain technology without cryptocurrency can not be considered wealthy.
Note that the US Securities and Exchange Commission (SEC) has already rejected the application of Gemini to start Bitcoin-ETF twice - in March 2017 and July 2018.
In December the Gemini Exchange introduced a mobile application for the Android and iOS operating systems.
