Bitcoin briefly dips almost 20%, rebounds to hover just over $15,000 US
Bitcoin lost almost a fifth of its value in 10 hours on Friday, having surged more than 40 per cent 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 US to $19,500 US in less than an hour on the U.S.-based GDAX, one of the biggest exchanges globally, while it was still changing hands at about $15,900 on the Luxembourg-based Bitstamp
Having then climbed to $16,666 on Bitstamp at around late morning on Friday, it tumbled to $13,482 in the afternoon, a slide of more than 19 per cent. It was last down 9.3 per cent at $15,091.97 on BitStamp.
Bitcoin pulled back ahead of the Chicago-based CBOE Global Markets exchange's launch of a futures contract on the digital currency on Sunday, to be followed by CME Group the next week.
Craig Erlam, senior market analyst, at OANDA in London said investors may have taken profits on their bitcoin gains ahead of the CBOE launch, which could open the door to short speculators who believe the price has risen far too quickly.
"The initial bounce after this morning's sell-off suggests there's still appetite for buying dips but that may not last if we don't see the kind of rebound witnessed previously," said Erlam. "Saying that, the way bitcoin is trading at the minute, I don't think anyone would be surprised to see it end the day in the green," he added.
As investors braced for the CBOE launch, some of the big U.S. banks, including JPMorgan Chase and Citigroup, will not immediately clear bitcoin trades for clients once investors start trading futures contracts, the Financial Times reported on Friday, citing people familiar with the matter.
JPMorgan and Citigroup did not immediately respond to requests for comment.
Goldman Sachs Group Inc. on Thursday said it is planning to clear bitcoin futures for some clients as the new contracts go live on the exchanges in the coming days.
As bitcoin slumped, other cryptocurrencies climbed. Ethereum the second-biggest, was up nearly 8 per cent, according to trade website Coinmarketcap.
For the week, bitcoin was still up almost a third. Since the start of October, bitcoin has more than tripled in price — its strongest quarterly performance since 2013. And since the start of the year, its value has increased about 15-fold, a rise that led to growing concerns the bubble would burst in dramatic fashion.
The rise has drawn in millions of new investors. So far this week, more than half a million new users have opened wallets with retail-focused bitcoin wallet provider Blockchain, the firm said, doubling the total number of users to 20 million since last year.
Some market-watchers say the most recent lurch higher in bitcoin can be explained by the coming launch of bitcoin futures on major derivatives exchanges "The fact that CBOE, CME and Nasdaq are preparing to launch Bitcoin trading instruments in the near future could be perceived by investors as a further step towards an international acceptance of Bitcoin," said Peter Iosif, analyst at currency broker IronFX.
