Bitcoin has “gone viral as a currency” and its price instability is a concern, economist Robert Shiller said Thursday.
Speaking at the World Economic Forum (WEF) in Davos, Switzerland, Shiller compared the cryptocurrency to other attempts to “change” currency.
Referring to concepts like the Unidad de Fomento — a Chilean unit of account that is constantly adjusted for inflation to maintain price stability — the Nobel Prize winner said bitcoin was “another really clever idea.”
“I tend to think of bitcoin as an experiment,” he said. “It is an interesting experiment, but it’s not a permanent feature of our lives. We are over-emphasizing bitcoin, we should broaden it out to blockchain, which will have other applications.” Blockchain is the technology that underpins bitcoin and other cryptocurrencies. It is a decentralized network that records cryptocurrency transactions.
Shiller said the world should be looking to mimic Chile’s Unidad de Fomento instead.
A number of critics have slammed the world of digital currencies recently over concerns of its volatile nature and of illegal activities associated with it — and the fact that it is near-impossible to regulate.
