Tokenomics

UNUS SED LEO ($LEO)

UNUS SED LEO (LEO) is a utility token introduced by Bitfinex in May 2019. It is intended to offer benefits within the iFinex ecosystem, such as trading fee reductions on platforms like Bitfinex.

The token features a buyback and burn system, where iFinex allocates a portion of its revenue to repurchase and remove LEO tokens from circulation, aiming to reduce supply over time. Initially issued equally on the Ethereum and EOS blockchains, LEO follows a deflationary model and provides tiered benefits for users holding larger amounts.

Token burn progress is documented transparently, and LEO is available for trading on exchanges, including Bitfinex, with common pairs such as BTC and USD. ^{[24] [38]}

Bitfinex Hack

On the 2nd of August 2016, Bitfinex suffered a hack in its system leading to a loss of 119,756 BTC worth about US$72 million at the time. Bitfinex halted Bitcoin withdrawals and trading after a breach was reported. Exchange customers, including those whose accounts had not been broken into, had their account balance reduced by 36% and received BFX tokens (debt tokens) in proportion to their losses. The BFX tokens could be used towards company equity or could be redeemed by Bitfinex. ^[33]

On the 25th of February 2019, Bitfinex was able to recover 27.7 BTC with the help of the U.S. government. In relation, two Israeli brothers, Eli and Assaf Gigi were arrested for their alleged involvement in the 2016 hack. ^[36]

An additional 6.5 BTC was recovered on 14th December 2021 in collaboration with Poloniex, a digital token exchange. ^[33]

The recovered funds were converted to USD and paid to RRT (Recovery Right Token) Holders. Bitfinex continues to pursue multiple strategies for recovery by collaborating with law enforcement and third parties to track and seize the stolen bitcoins as soon as they reach any exchange or business.

In February 2022, a New York couple, Ilya Lichtenstein and his wife Heather R. Morgan were arrested and charged by the U.S. federal authorities for conspiring to launder the stolen funds and defraud the United States. Of the 119,756 BTC stolen from the Bitfinex platform, the U.S. Department of Justice (DOJ) recovered nearly 94,000 BTC (worth approximately $3.6 billion at the time of recovery). In a statement, Deputy Attorney General Lisa Monaco said it was “the department’s largest financial seizure ever". ^[34][35]

In an announcement to their community, Bitfinex explained that they will work with the DOJ to establish their rights to a return of the stolen bitcoin. They also explained that if they receive a recovery of the stolen bitcoin, as described in the UNUS SED LEO token white paper, Bitfinex will, within 18 months of the date it receives that recovery use an amount equal to 80% of the recovered net funds to repurchase and burn outstanding UNUS SED LEO tokens. These token repurchases can be accomplished in open market transactions or by acquiring UNUS SED LEO in over-the-counter trades, including directly trading bitcoin for UNUS SED LEO. ^[33]

In 2024, Ilya Lichtenstein received a five-year sentence for the hack, while his wife, Heather Morgan, was sentenced to 18 months for laundering the funds. ^[37]
