The five stages of every bubble, according to Hyman Minsky
Economist Hyman Minsky described a pattern that repeats in practically every historical bubble, regardless of the specific asset: first a displacement (a real innovation, technological or financial, that justifies genuine initial optimism); then a boom, when prices start rising steadily; then euphoria, when caution disappears and buying 'because it can only go up' becomes the dominant strategy; then profit-taking, when the most informed investors start quietly selling; and finally panic, when the price collapses as fast, or faster, than it rose.
Dutch tulip mania (1636-1637)
In the Dutch Golden Age, the tulip (a flower recently imported from the Ottoman Empire) became the object of frenzied speculative trading. Bulbs of the most exotic varieties, with petals streaked by a virus nobody understood at the time, came to be traded through futures contracts in taverns, long before that season's actual flower even existed.
according to the most widely cited historical records, a single bulb of the Semper Augustus variety once traded for goods worth the equivalent of a skilled craftsman's annual salary multiplied several times over, figures comparable to the price of a house on an Amsterdam canal. The market collapsed in February 1637, when at a routine auction, buyers simply stopped showing up.
1720: two twin bubbles on either side of the English Channel
In 1720, France and England lived through, almost in parallel, two of history's most spectacular bubbles. In France, Scottish economist John Law convinced the crown to grant his Mississippi Company a monopoly on trade with France's North American colonies, funded partly by issuing paper money, one of the first large-scale historical tests of central banking and fiat money. The company's shares multiplied twentyfold in a year, before collapsing almost completely when investors tried to convert their shares and paper money into real silver coin en masse.
In England, the South Sea Company staged an almost identical episode, fueled by speculation over supposedly hugely profitable trade with South America that never materialized at that scale. Among the victims of the subsequent collapse was, according to the well-known historical anecdote, Isaac Newton himself, who lost a considerable sum and reportedly remarked that he could calculate the motion of the stars but not the madness of people.
The dot-com bubble (1995-2000)
In the late 1990s, the arrival of the internet created a genuine, real technological displacement, exactly the kind of innovation that, according to Minsky, tends to spark a bubble. The Nasdaq index multiplied more than fivefold between 1995 and its March 2000 peak, driven by companies going public with barely any revenue, let alone profits, valued using metrics invented for the occasion, like the number of unique visitors ('eyeballs'), instead of traditional financial indicators.
The unwind was as abrupt as the rise: the Nasdaq lost about 78% of its value between March 2000 and October 2002. Companies like Pets.com, an emblem of the era, went bankrupt within months after spending fortunes on advertising with no business model capable of sustaining those costs with real revenue.
The common thread: why 'this time is different' almost never is
Separated by nearly four centuries, tulip mania and the dot-com bubble share the same ingredients: a narrative of genuine radical change (an exotic flower, a truly transformative new technology), abundant credit or liquidity that makes it easy to buy with borrowed or speculative money, and the conviction, repeated in every cycle with the same words, that 'this time is different' and the usual valuation rules no longer apply.
This doesn't mean every real innovation is a bubble in disguise: the internet, over time, did change the economy as much as, or more than, its most optimistic champions predicted back in 1999. The problem is never the innovation itself, but the price paid for it once euphoria completely replaces analysis. That's the same caution worth applying today to any asset marketed as 'the next revolution,' from bitcoin to artificial intelligence: the relevant question isn't whether the technology is real, but whether today's price is already pricing in decades of future success that hasn't happened yet.

Frequently Asked Questions
Almost all of them follow the same pattern described by Hyman Minsky: an initial displacement (a real innovation), a price boom, a phase of speculative euphoria, quiet profit-taking by the most informed players, and finally a selling panic that reverses much of the rise in far less time than it took to build up.
Some modern economic historians qualify the scale of the episode and its actual impact on the Dutch economy as a whole, beyond a relatively narrow circle of specialized traders. The episode remains, nonetheless, the most cited example of speculative mania precisely because it illustrates the pattern so clearly.
Bitcoin has shown historical volatility far higher than most traditional assets, with drawdowns of over 70% on several occasions from prior peaks, a pattern it shares with historical speculative episodes. Whether or not its long-term value is justified by its fundamentals is an open debate outside the scope of this guide; what is verifiable is that its track record of extreme volatility calls for caution, regardless of anyone's opinion about its future.
By keeping a diversified portfolio instead of concentrating in whatever asset is fashionable at the moment, staying wary of any investment justified only by 'it's going to keep going up,' and avoiding excessive leverage, which is precisely what turns a normal price drop into a devastating loss in nearly every historical episode.
