Apple co-founder Steve Wozniak has given a glowing endorsement of bitcoin, saying that he hopes the cryptocurrency will one day serve as a global single currency.
Mr Wozniak was responding to comments made by Twitter CEO Jack Dorsey earlier this year, who claimed that bitcoin would become the world's single currency within 10 years.
"I buy into what Jack Dorsey says, not that I necessarily believe it's going to happen, but because I want it to be that way, that is so pure thinking," Mr Wozniak told CNBC.
"Bitcoin is mathematically defined, there is a certain quantity of bitcoin, there's a way it's distributed... and it's pure and there's no human running, there's no company running and it's just... growing and growing."
The decentralized nature of bitcoin meant that it is "natural," Mr Wozniak added, saying: "Nature is more important than all our human conventions."
