Greater than two years after warning U.S. lawmakers that cryptocurrencies are “the mom of all scams and bubbles,” economics professor Nouriel Roubini stays a hater.
“For the reason that basic worth of bitcoin is zero and could be damaging if a correct carbon tax was utilized to its huge polluting energy-hogging manufacturing, I predict that the present bubble will ultimately finish in one other bust,” Roubini wrote in an opinion column for the Financial Times on Wednesday.
Since his October 2018 warning, bitcoin
has surged greater than 600% and is presently hovering at $45,000, up practically 60% to this point this yr. A latest leg increased briefly took bitcoin to $48,000 on Tuesday, sparked by a $1.5 billion funding from electric-car maker Tesla

Acknowledging Tesla, Roubini mentioned bitcoins are nonetheless “barely utilized by official corporations.” He additionally harked again to the final bitcoin bubble of 2017-18, when the cryptocurrency went from $1,000 to $20,000 then again to $3,000.
And don’t even discuss with cryptocurrencies as “currencies,” as virtually nothing is priced in them, he mentioned. “They aren’t a scalable technique of fee: with bitcoin you are able to do 5 transactions per second whereas the Visa community does 24,000.”
Then there may be the volatility, which may wipe out earnings inside hours and the truth that counting on cryptocurrency tokens marks a return to the Stone Age, a dig he’s made before. Invoking that “fashionable Stone Age” cartoon household, he mentioned even the Flintstones “had a extra refined financial system based mostly on a benchmark” — shells.
Crypto, he says, is “solely a play on a speculative asset bubble, worse than tulip-mania, as flowers had and nonetheless have utility. Its retailer of worth in opposition to tail dangers is unproven. And worse: some cryptos, dubbed “‘shitcoins,’ are monetary scams within the first place or debased day by day by their sponsor,” mentioned the professor of economics at New York College’s Stern College of Enterprise and chairman of Roubini Macro Associates.
And cryptocurrencies received’t “decentralize finance, present banking companies to the unbanked, or make the poor wealthy,” as a result of the mining of bitcoins, for instance, is generally managed by oligopolistic miners, in far-flung locations reminiscent of Russia, China or Belarus.
Neither will bitcoin nor its rivals present that protected haven traders are in search of — hedges in opposition to inflation, weak currencies and tail dangers amid unfastened financial coverage, monetary disaster and geopolitical stress. “Gold, inflation-based bonds, commodities, actual property and even equities are all affordable candidates,” Roubini wrote.
