Bitcoin’s meteoric rise last year had many observers calling it one of the biggest speculative manias in history. The cryptocurrency’s 2018 crash may help cement its place in the bubble record books.
Bitcoin’s meteoric rise last year had many observers calling it one of the biggest speculative manias in history. The cryptocurrency’s 2018 crash may help cement its place in the bubble record books.

Down about 70 percent from its December high after sliding for a fourth straight day on Friday, Bitcoin is getting ever-closer to matching the Nasdaq Composite Index’s 78 percent peak-to-trough plunge after the U.S. dot-com bubble burst. Hundreds of other virtual coins have all but gone to zero — following the same path as Pets.com and other red-hot initial public offerings that flamed out in the early 2000s

While Bitcoin has bounced back from bigger losses before, it’s far from clear that it can repeat the feat now that much of the world knows about cryptocurrencies and has made up their mind on whether to invest. Bulls point to the Nasdaq’s eventual recovery and say institutional investors represent a massive pool of potential cryptocurrency buyers, but regulatory and security concerns have so far kept most big money managers on the sidelines.
Bitcoin may not go to zero, but it’s “very much” a bubble, Robert Shiller, the Nobel laureate economist whose warnings about dot-com mania proved prescient, said in an interview with Bloomberg Television’s Tom Keene on Tuesday. Last year’s Bitcoin surge was “not a rational response,” he said.
