Bitcoin bloodbath nears dotcom levels as currency slides 70pc since last year
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 70pc 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 78pc peak-to-trough plunge after the US dotcom 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.
"You'll have to see the market reverse before you see institutions pile in," Peter Smith, chief executive officer of Blockchain Ltd, which introduced a crypto trading platform for professional investors last week, told Bloomberg Television.
Bitcoin declined as much as 4.2pc to $5,791 last Friday, the lowest level since November, according to Bloomberg composite prices.
It traded at $5,878 as of 10.33am in New York, down 59pc for the year and heading for a second- quarter loss of 14pc.
Other coins including Ether and Litecoin slumped more, while the combined value of tokens tracked by CoinMarketCap.com declined to $236bn.
At the peak of crypto-mania, they were worth about $830bn.
While it was difficult to find fresh catalysts for Bitcoin's drop on Friday, hacks at two South Korean exchanges and a regulatory clampdown in Japan have weighed on market sentiment in recent weeks.
Regulators around the world have stepped up scrutiny of cryptocurrencies on concern that they're a breeding ground for illicit activity including money-laundering, market manipulation and fraud.
Lesser-known tokens have been hit the hardest. Dead Coins lists around 800 that are effectively worth nothing, while Coinopsy puts the tally at more than 1,000.
Fewer than 4pc of coins with market caps from $50m to $100m were successful or promising, according to a March analysis from ICO advisory firm Satis Group.
Bitcoin may not go to zero, but it's "very much" a bubble, Robert Shiller, the Nobel laureate economist whose warnings about dotcom mania proved prescient, said in an interview with Bloomberg Television's Tom Keene.
Last year's Bitcoin surge was "not a rational response", he said.
