Bitcoin hit a record high on Sunday closing at $11,826.76.
The Winklevoss twins are now the first Bitcoin billionaires.
After surging past $11,000 on 29 November, bitcoin's value fell to almost $9,000 in volatile trading, before recovering at the weekend.
Whilst the legitimacy of the digital currency continues to be debated, the Winklevoss twins were firm believers in taking a punt, telling the Telegraph in a past interview that it's "like a better version of gold", with the potential to reach the value of trillions.

The digital currency retraced some of its gains Sunday after hitting the peak. A likely candidate: the mysterious father of bitcoin, known as Satoshi Nakamoto, who was the first to mine bitcoin at a time when it was far easier to unlock the cryptocurrency. They later also spent nearly $1 million to buy more bitcoin later in 2013, right after Silk Road, an illicit marketplace on the so-called dark web, was seized by the Federal Bureau of Investigation.
Like billionaire technology angel investor Tim Draper, the Winklevoss twins have allocated a significant portion of their resources and capital in providing a better infrastructure for the bitcoin market, specifically for investors in the traditional finance market.

Still, the twins themselves have noted that older Bitcoin aficionados probably have larger holdings.
The question now is, will they sell? This is the clearest indication that professional investors are looking at Bitcoin as a serious investment asset. However, it looks like Bitcoin is here to stay.
