Third, it has to be a stable store of value in terms of being a store of wealth and of purchasing power over goods and services. We don't like high inflation because it changes the purchasing power of monetary balances. So high instability in the price of a currency is not good. Now, if you look at bitcoin — or the hundreds of other cryptocurrencies — they're not units of account. There are no goods or services that are priced in bitcoin.

Secondly, it's not even a stable numeraire. You have this cacophony since you have thousands of cryptocurrencies: there's no way you can use any of them to have a stable numeraire to price all the goods and services in the economy. Indeed, in the utopian dream of decentralization of many people in the crypto world, they believe that there should be a different cryptocurrency for every good or service out there; that is the equivalent of returning to barter.

So it fails the first criterion. Secondly, it fails the criterion of being a means of payment. Ethereum allows seven or eight transactions per second. A standard credit or debit card network allows upwards of 25, transactions per second. Something cannot be a viable means of payment if it cannot do more than five transactions per second.

There are massive technological constraints. Three, it's not a stable store of value or purchasing power over goods or services. Suppose you're a merchant and you're accepting, say, bitcoin for payment. You receive a payment in bitcoin in the morning and by the afternoon the price has fallen 10 percent or 20 percent. Where is the stable purchasing power? People talk about these things as being an alternative to fiat money, but they fail on every dimension of what a currency should be. It's a misnomer, in fact, to call them cryptocurrencies in the first place.

They are not currencies by any reasonable definition. When you look at the pricing of these cryptocurrencies, they look like typical bubbles. You have exponential increases of the value of the assets totally unrelated to the underlying fundamental value.

Those bubbles, in the three years before their peaks, went up by 5X, 10X, or 30X at the maximum. Bitcoin went up by 60X. The boom was exponential. And the subsequent bust has been as exponential as the bubble. The peak of this bubble was During that year alone it went up by 20X. This had nothing to do with fundamentals. He used an intuitive, historical approach backed up by an understanding of theoretical models to analyze these countries and came to the conclusion that a common denominator was the large current account deficits financed by loans from abroad.

Roubini theorized that the United States might be the next to suffer, and as early as began writing about a possible future collapse. But since , real home prices have increased by about 90 percent. There is no economic fundamental—real income, migration, interest rates, demographics—that can explain this.

It means there was a speculative bubble. And now that bubble is bursting. When asked whether the real estate ride was over, he said, "Not only is it over, it's going to be a nasty fall. And now that model has broken down because we borrowed too much. He feels that " sustainable growth may mean investing slowly in infrastructures for the future, and rebuilding our human capital," by investing in renewable resources. It's not going to be simple. When these attitudes reverse at the end of the recession, that would be time for an "exit strategy, of mopping up that liquidity" and taking some of the money back out of circulation, "so it doesn't just bid up house prices and stock values in a new bubble.

And that will be 'very, very tricky indeed,'" he stated. Indeed, like Argentina, Italy faces a growing competitiveness loss given an increasingly overvalued currency and the risk of falling exports and growing current account deficit. The growth slowdown will make the public deficit and debt worse and potentially unsustainable over time.

And if a devaluation cannot be used to reduce real wages, the real exchange rate overvaluation will be undone via a slow and painful process of wage and price deflation. He said in September, , "we have a subprime financial system, not a subprime mortgage market". In Europe , Canada , Japan , and the other advanced economies, it will be severe. Nor will emerging market economies—linked to the developed world by trade in goods, finance, and currency—escape real pain.

Roubini notes that the subprime issues are a global, and not just a U. In an interview with author James Fallows in late spring of , he stated, "People talk about the American subprime problem, but there were housing bubbles in the U.

It was not just the U. The global financial pandemic that I and others had warned about is now upon us. But we are still only in the early stages of this crisis. My predictions for the coming year, unfortunately, are even more dire: The bubbles, and there were many, have only begun to burst".

The problems of Citi , Bank of America and others suggest the system is bankrupt. In Europe, it's the same thing. The insolvent ones you have to shut down. You need command-economy allocation of credit to the real economy. Not enough is being done," he felt at the time. This is where we move from a private to a public debt problem We socialised part of the private losses by bailing out financial institutions and providing fiscal stimulus to avoid the great recession from turning into a depression.

But rising public debt is never a free lunch, eventually you have to pay for it. What is happening today in Greece is the tip of the iceberg of rising sovereign debt problems in the eurozone, in the UK, in Japan and in the US. However, he stated that "even they realize that the very excess of American demand has created a market for Chinese exports.

I don't think even the Chinese authorities have fully internalized the contradictions of their position. In an article in Foreign Affairs magazine, they describe what they call a " G-Zero world ," where the United States no longer has the resources to continue as the primary provider of global public goods. As a result, there is likely to be more conflict than cooperation between countries, creating a " zero-sum game ," a "game in which my win is your loss.

Japan is likewise tied down with complex political and economic problems at home. None of these powers' governments has the time, resources, or domestic political capital needed for a new bout of international heavy lifting.

Nothing is priced in bitcoin, it's not a scalable means of payment, it's not a stable store of value given its high volatility, and the prices of different items are not denominated in cryptocurrencies "because there are thousands of tokens and thus limited price transparency," Roubini said. The economist highlighted that bitcoin can only complete seven transactions per second, compared to the Visa network which can conduct 65, transactions per second.

While cryptocurrencies are not currencies, according to Roubini, they are also not assets. Because of that, cryptocurrencies are in a bubble, according to Roubini. But we can't even determine the fundamental value of these cryptocurrencies, and yet their prices have run up dramatically," Roubini explained. And corporations adding bitcoin to their balance sheet seems far fetched due to that high volatility. This is the story of Clifton Collins, a former security guard, who thinks Karma got to him for his wrongdoings.

But, in reality, what got to him is his decision to use bitcoin, a digital asset that could store millions of dollars digitally and conveniently inside a teeny-tiny metal box. Collins merely forgot that he was concentrating all his wealth on a piece of paper that was prone to get stolen, burnt, or lost. Nouriel Roubini — Bitcoin believers call him Dr.
