UNUS SED LEO (LEO) is a cryptocurrency utility token associated with the Bitfinex and iFinex ecosystem. Unlike many cryptocurrencies that primarily focus on payments or decentralized applications, LEO was designed to provide utility within the Bitfinex ecosystem and offer certain benefits to eligible token holders.
In this guide, we will explain what LEO Token is, how it works, its history, token supply, LEO burn mechanism, blockchain support, and why it is followed by cryptocurrency users.
What Is UNUS SED LEO (LEO)?
UNUS SED LEO, commonly known as LEO Token, is a utility token launched by iFinex for the Bitfinex community. The token was introduced in 2019 and was designed to provide utility across the Bitfinex ecosystem.
According to Bitfinex, LEO was created to provide benefits and functionality for users of its trading platform. The original LEO token sale raised approximately one billion USDt worth of funds during its initial offering.
The name “UNUS SED LEO” comes from a Latin phrase associated with the idea of quality over quantity.
When Was LEO Token Launched?
UNUS SED LEO was launched in May 2019. It was initially offered through a private sale and quickly became an important part of the iFinex ecosystem.
The token was introduced as a utility asset rather than simply as a cryptocurrency designed for payments. Its primary purpose has been connected with benefits and services within the Bitfinex ecosystem.

How Does LEO Token Work?
LEO is designed to work as a utility token within the Bitfinex ecosystem. Depending on the applicable Bitfinex terms and fee schedules, holding LEO can provide certain benefits.
These benefits can include:

Bitfinex’s current documentation notes that LEO-related benefits and fee schedules can change over time, so users should check the latest official information before relying on any particular benefit.
LEO Token Burn Mechanism
One of the notable features of UNUS SED LEO is its token repurchase and burn mechanism.
The LEO ecosystem includes a process through which LEO tokens are repurchased and burned. Burning tokens permanently removes them from circulation, which can reduce the total supply over time.
Bitfinex’s LEO transparency information provides details about token acquisitions and burn transactions. The official LEO website also provides a dashboard showing burn-related information.
It is important to understand that a token burn does not automatically mean that the token price will increase. Market prices depend on many factors, including demand, market conditions, liquidity and broader cryptocurrency trends.
LEO Token Supply
LEO has a large token supply, with a portion of the original supply already removed through the burn mechanism.
Current market-data sources can show the circulating supply, total supply, market capitalization and other statistics. Because cryptocurrency data changes continuously, readers should check a live market-data source for the latest numbers rather than relying on a static figure in an article.
