Bitfinex has announced that some of the bitcoins stolen in a major 2016 hack have been returned after they were retrieved by the U.S. government.

In a blog post published Monday, the exchange said that 27.66270285 BTC – worth just over $104,000 at time of writing – have been received from the U.S. government, and come as the result of U.S. law enforcement efforts.

Bitfinex said that, since the hack, it has been collaborating with international law enforcement agencies “to provide intelligence and assist with investigations,” adding:

“Bitfinex was alerted in November 2018 that the U.S. government had obtained bitcoins believed to be proceeds from the 2016 hack.”

The August 2016 hack, in which a total of 119,756 BTC were stolen, shocked the crypto market with the largest loss of bitcoins by an exchange since Japan’s Mt. Gox huge breach in early 2014.

The returned funds represent about 0.023 percent of the total taken in the attack.

As pledged in its recovery strategy formulated after the 2016 breach, the returned funds are being converted to U.S. dollars and will be paid to current holders of its RRT (Recovery Right Token) token.

To compensate for the hack losses in 2016, the exchange generalized the losses across all accounts and credited BFX tokens to customers at a ratio of 1 BFX to every dollar stolen.

“Within eight months of the security breach, all BFX token holders had their tokens redeemed at 100 cents on the dollar or exchanged their tokens for, directly or indirectly, shares of the capital stock of iFinex Inc. All BFX tokens were destroyed within this process,” Bitfinex said in Monday’s post.

Bitfinex created the tradable RRT token for BFX holders allowing them to convert BFX tokens into shares of iFinex, it added.

After any outstanding or unconverted BFX token holders have been reimbursed, as per the recovery plan, recovered funds were set to be distributed to RRT holders, up to 1 dollar per RRT.

“As all BFX tokens have been redeemed and destroyed, the full amount of recovered bitcoins today is being distributed pro rata to the RRT holders,” Btfinex stated.

Thanking the U.S. federal law enforcement agencies for their efforts in investigating the attack and returning the stolen funds, Giancarlo Devasini, chief financial officer at Bitfinex, said:

“Over two years following the hack of the Bitfinex platform, today we see the results of a clear and robust response strategy and the efforts of the U.S. government. It gives us great pleasure to be able to reimburse our traders that were loyal to us and believed in us at a very difficult time.”

The exchange, he continued, will continue to assist law enforcement with their inquiries. With much of the stolen bitcoin still missing, Devasini called for the hackers, or anyone with information about the breach, to make contact “to finally resolve the situation in a mutually beneficial manner.”
