Ashton Kutcher: You could say that Ashton Kutcher was one of the earliest celebrity adopters of the currency, because he has been talking about it since 2013. Kutcher was always a big fan of the virtual coins since he heard about them and has encouraged others to begin using them as well.

Nas: This rapper has endorsed the virtual currency for its self-regulation that doesn’t depend on the government. He has never been one to trust governments, so Bitcoin presents a logical solution for anyone who has a similar sentiment.

Bill Gates: The founder of Microsoft has always been a fan of disruptive and innovative technologies. Bitcoins have been marked as another such technology that he supports.

Al Gore: Al Gore has stated that he likes the fact bitcoins replace the need for government regulation by using a complex algorithm instead.

Richard Branson: This British investor is up for anything that will help him to earn more money from his array of companies.

Tyler and Cameron Winklevoss: For the longest time, it looked like the Winklevoss twins fate in life was to be known for losing out to Mark Zuckerberg for control of Facebook.
