London/Tokyo: Bitcoin lost almost a fifth of its value in 10 hours on Friday, having surged more than 40% in the preceding 48 hours, sparking fears the market may be heading for a price collapse.
In a hectic day on Thursday, bitcoin leapt from below $16,000 to $19,500 in less than an hour on the US-based GDAX, one of the biggest exchanges globally, while it was still changing hands at about $15,900 on the Luxembourg-based Bitstamp.
