what's UNUS SED LEO?

UNUS SED LEO (LEO) is a utility token launched by iFinex Inc., the parent company of the Bitfinex cryptocurrency exchange, in May 2019. It was created as part of a settlement with the New York Attorney General to provide benefits to the exchange's users and support platform operations. Holders of LEO can use the token to receive discounts on trading fees, with the discount percentage increasing based on the amount held and traded on Bitfinex. The token operates on the Ethereum blockchain as an ERC-20 standard asset. The LEO token ecosystem is integrated directly into Bitfinex's trading infrastructure, where it incentivizes loyalty and reduces costs for active traders. A portion of the exchange's revenue is used to buy back and burn LEO tokens, aiming to create deflationary pressure over time. This mechanism ties the token's value to the overall health and volume of the Bitfinex platform. LEO does not have its own independent blockchain but leverages Ethereum for transfers and smart contract interactions. Beyond fee discounts, LEO serves as a governance and utility asset within the iFinex family of products, including potential future expansions into lending and margin trading features. Its design emphasizes long-term utility for exchange users rather than speculative trading, with a total supply capped at 986 million tokens, of which a significant portion is already in circulation.
