SAN FRANCISCO — The price of Bitcoin plunged to its lowest point since 2020. Coinbase, the large cryptocurrency exchange, tanked in value. A cryptocurrency that promoted itself as a stable means of exchange collapsed. And more than $300 billion was wiped out by a crash in cryptocurrency prices since Monday.
The crypto world went into a full meltdown this week in a sell-off that graphically illustrated the risks of the experimental and unregulated digital currencies. Even as celebrities such as Kim Kardashian and tech moguls like Elon Musk have talked up crypto, the accelerating declines of virtual currencies like Bitcoin and Ether show that, in some cases, two years of financial gains can disappear overnight.
The moment of panic amounted to the worst reset in cryptocurrencies since Bitcoin plummeted 80 percent in 2018. But this time, the falling prices have broader impact because more people and institutions hold the currencies. Critics said the collapse was long overdue, while some traders compared the alarm and fear to the start of the 2008 financial crisis.
“This is like the perfect storm,” said Dan Dolev, an analyst who covers crypto companies and financial technology at the Mizuho Group.
