SINGAPORE/TOKYO/NEW YORK (Reuters) – Bitcoin rose 15 percent on Tuesday, recouping about half of the losses it sustained last week, its worst since 2013, as investors who had missed out on earlier rallies bought the world’s biggest and best-known digital currency.

While bitcoin investors and analysts believe last week’s 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.

Bitcoin fell nearly 30 percent at one stage on Friday to $11,159.93. At 3:09 p.m. (2009 GMT) on Tuesday, bitcoin was up 15 percent at $16,030 in light trading on the Luxembourg-based Bitstamp exchange.

“The latest price move shows bitcoin is still a speculative investment. There is enormous amount of volatility there,” said Kristina Hooper, chief global market strategist with Invesco in New York.

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 Dec. 17 on Bitstamp and to over $20,000 on other exchanges.

“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 that encompasses all features of a digital economy based on cryptocurrency.
