DHAKA: Nearly 120,000 units of digital currency bitcoin worth about US$72 million was stolen from the exchange platform Bitfinex in Hong Kong, rattling the global bitcoin community in the second-biggest security breach ever of such an exchange.

Bitfinex is the world’s largest dollar-based exchange for bitcoin, and is known in the digital currency community for having deep liquidity in the US dollar/bitcoin currency pair, reports Yahoo Finance.

Zane Tackett, Director of Community & Product Development for Bitfinex, told the media on Wednesday that 119,756 bitcoin had been stolen from users’ accounts and that the exchange had not yet decided how to address customer losses.

“The bitcoin was stolen from users’ segregated wallets,” he said.

The company said it had reported the theft to law enforcement and was cooperating with top blockchain analytic companies to track the stolen coins.

Last year, Bitfinex announced a tie-up with Palo Alto-based BitGo, which uses multiple-signature security to store user deposits online, allowing for faster withdrawals.

“Our investigation has found no evidence of a breach to any BitGo servers,” BitGo said in a Tweet.

“With users’ funds secured using multi-signature technology in partnership with BitGo, a lot more is at stake for the backbone of the bitcoin industry, with its stalwarts and prided tech under fire,” said Charles Hayter, chief executive and founder of digital currency website CryptoCompare.

The security breach comes two months after Bitfinex was ordered to pay a $75,000 fine by the US Commodity and Futures Trading Commission in part for offering illegal off-exchange financed commodity transactions in bitcoin and other digital currencies.
