Bitcoin, the world’s biggest and best-known cryptocurrency, lost more than a quarter of its value in a single day, falling 30% at one stage on Friday to $11,159.93. Despite a late recovery, it had its worst week since 2013.
The digital currency had risen around twentyfold since the start of the year, climbing from less than $1,000 to as high as $19,666 on 17 December on Bitstamp and to more than $20,000 on other exchanges. However, it has posted heavy declines since.
While bitcoin investors and analysts believe the decline in its value was a natural correction after a heady run-up in prices, there have been further warnings from market regulators and central banks.
“There is no right current price which would reflect the right current valuation,” said Andrei Popescu, Singapore-based co-founder of COSS, which describes itself as a platform encompassing all features of a digital economy based on cryptocurrency.
“Taking profit is right, while buying into a long-term projection is also right. You don’t have to be right in this market, just less wrong than the rest,” Popescu said.
Shmuel Hauser, the chairman of the Israel Securities Authority, said on Monday he would propose regulation to ban companies based on bitcoin and other digital currencies from trading on the Tel Aviv Stock Exchange.
Singapore’s central bank warned last week against investment in cryptocurrencies, saying it considered the recent surge in prices to be driven by speculation and that the risk of a sharp fall in prices was high.
Prices of rival cryptocurrencies, which slid along with bitcoin last week, have also recovered, with Ethereum, the second-biggest cryptocurrency by market size, quoted around $771, up from Sunday’s low of $689 but still far from highs of around $900 hit last week.
