2013 was the tipping point for Bitcoin, the digital currency that has grown steadily over the past few years and surpassed $1,000 in value last month. Evolving from a small base of geeky zealots, Bitcoin is being accepted in new locations every day.
Still, it remains controversial. While even executives at Bank of America have given it credit, some high-profile economists have railed against it, calling it "rat poison" and even a "Ponzi scheme."
So, naturally, everyone wants to know what celebrities think about it. As a result, the Bitcoin community now counts among it a pretty eccentric list of celebrities, some of whom want to use it for currency, others who want to use it for publicity.
