The co-founder of Apple Steve Wozniak hopes that Bitcoin will be the world’s single currency that offers a viable alternative to national currencies, though he isn’t convinced this will come to pass.

Speaking on the sidelines of Europe’s largest Fintech event – Money 20/20 Europe, Wozniak told CNBC that he liked the “purity” of the idea that people all over the world could someday share a single currency, despite being separated by national borders.

He said: “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.”

As CCN reported, Dorsey, who is CEO of both social media giant Twitter and digital payment processor Square, said recently that he believes Bitcoin will be the world’s only currency – perhaps even within a decade.

The “Woz” has long expressed his interest in the Bitcoin project – a fact that has not changed since he decided to sell most of his holding after finding that he spent too much time watching price movements.

Reiterating comments that he made in the past, Wozniak said that Bitcoin is “pure digital gold” and – unlike many cryptocurrencies – “totally decentralized” since it is not run by any single company and does not have a business model.

He said: “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… and surviving”.

“That to me says something that is natural and nature is more important than all our human conventions.”

Ostensibly, Wozniak is also strongly bullish on Ethereum, especially since it is more than just a store of value, but a platform for decentralised applications to be built upon. Last month, he said he believes the project could become the next Apple in terms of its status in the technology sector.
