Bitcoin miner NiceHash reveals $60M hack as price rockets past $16,000 US – Business


The Slovenian-based bitcoin miner NiceHash says it is investigating a security breach and the possible theft of tens of millions of dollars’ worth of bitcoins, as meanwhile the value of the virtual currency has soared to a new record high.

NiceHash said Thursday in a statement posted on its website that it had stopped operations for 24 hours and was working to verify how many bitcoins were taken.

There was no immediate response from NiceHash to an emailed request for more details. Reports suggest  4,700 bitcoins were missing — which would have been valued at more than $60 million at the time of the theft.

“The incident has been reported to the relevant authorities and law enforcement and we are co-operating with them as a matter of urgency,” it said.

The statement urged users to change their online passwords.

Troubles with the website over the past day or so drew alarm and complaints, with many bitcoin owners posting panicked comments on NiceHash’s social media accounts.

The price of bitcoin has surged to more than $16,000 US on Thursday morning, gaining roughly $3,000 in less than 24 hours, according to coindesk, a website that monitors the price. That compares with a value below $1,000 at the beginning of the year. At the end of the trading day, bitcoin stood at $15,768.

Another major coin exchange, coinbase, crashed under a flurry of server requests. Prices for bitcoin fluctuate from one exchange to another.

At current valuations, the total value of all bitcoin currently in existence is roughly $250 billion US. That’s more than Canada’s two largest banks, Royal Bank and Toronto-Dominion Bank, are worth — combined.

“I’m kind of taken aback by what’s happened in the last three months,” said Richard Johnson, an analyst at Greenwich Associates who owns digital currencies and considers himself a bitcoin bull. “I’m concerned things are moving a bit too quickly.”

Bitcoin is the world’s most popular digital currency. Such currencies are not tied to a bank or government and allow users to spend money anonymously. They are basically lines of computer code that are digitally signed each time they are traded. Miners of bitcoins and other virtual currencies help keep the systems honest by putting computer power into a blockchain, a global running tally of every transaction that prevents cheaters from spending the same digital coin twice.

NiceHash is a cryptocurrency mining application that lends computer power to verify bitcoin users’ transactions.

Online security is a vital concern for such dealings.

In Japan, following the failure of a bitcoin exchange called Mt. Gox, new laws were enacted to regulate bitcoins and other cryptocurrencies. Mt. Gox shut down in February 2014, saying it lost about 850,000 bitcoins, possibly to hackers.
