If there are two massive and well known names associated with Bitcoin, it is the Winklevoss twins - Tyler and Cameron. The former Olympic rowers have recently become the first Bitcoin billionaires and this has led to even more positive news for the cryptocurrency. Not only will it give financial investment organisations the confidence to consider Bitcoin more, but it will also interest many members of the public in digital currencies too.If you recognise the Winklevoss name, it's probably because of their previous legal wrangle with Facebook founder Mark Zuckerberg. The Winklevoss twins accused Zuckerberg of stealing the idea for the social media giant from them and ended up taking him to court over it. Since then, they have been busy and their early adoption of Bitcoin in 2011 has proved to be very wise indeed! They initially bet $11 million of their own money on the cryptocurrency becoming successful - at today's prices, their Bitcoin is now worth over £1 billion.2017 continues to be a great year for Bitcoin when you look at this story. It is simply superb publicity for the cryptocurrency and will give further validation of its worth and respectability to many observers. Although Bitcoin did hit a recent dip, it has since come back stronger to sit over the $11,000 mark at the time of writing.This resurgence and interest around the Winklevoss twins could well attract even more investors and the public toward the premier cryptocurrency. Nasdaq is reportedly ready to follow the CME Group in launching a Bitcoin futures contracts next year - this will be a clear signal to all that professional investment institutions are taking Bitcoin seriously.It is well-known in the Bitcoin world that the Winklevoss twins are long-term Bitcoin bulls. With the continued rise of the cryptocurrency expected to continue into the future, it would seem likely that they will not be about to change their view soon. Their recent success in hitting the $1 billion mark would certainly suggest their position is the correct one to take in the current market conditions.
