Bitcoin flirted with $17,000 on Thursday, triggering a warning the cryptocurrency is “like a charging train with no brakes” and prompting fresh concern about its looming launch on mainstream markets.
Still under $14,000 in Asian trading hours, it smashed through $15,000 in European trading and then later surged to $16,777.08 around 1630 GMT, according to Bloomberg data.
The rally came just a day after the virtual currency, which has been used to buy everything from an ice cream to a pint of beer, hit the $12,000 mark for the first time, while it has soared nearly 70 percent in value in just one week.
Bitcoin — which came into being in 2009 as a bit of encrypted software and has no central bank backing it and no legal exchange rate — has risen from a 2017 low of $752 in mid-January and surged dramatically in the past month.
The increased interest has been driven by growing acceptance among traditional investors of an innovation once considered the preserve of computer nerds and financial experts.

But some, including the US Federal Reserve, have warned against dabbling in bitcoin as it could threaten financial stability, and fears of a bubble have increased as the price has soared.
“Bitcoin now seems like a charging train with no brakes,” said Shane Chanel, from Sydney-based ASR Wealth Advisers. “There is an unfathomable amount of new participants piling into the cryptocurrency market.”
But he warned: “Once the hype slows down, we will most certainly see some sort of correction.”
There are mounting concerns about its introduction into the mainstream financial system after US regulator the Commodity Futures Trading Commission last week cleared the way for bitcoin futures to trade on major exchanges, a decision which analysts say has helped spur the recent rally.
Bitcoin is to be offered on the CBOE Futures Exchange from this weekend and on the world’s biggest futures venue, the Chicago Mercantile Exchange (CME), from December 18.
