How Unus Sed Leo (LEO) Works

Unus Sed Leo (LEO) is a cryptocurrency launched in May 2019 by the popular crypto exchange Bitfinex. LEO was created as a utility token for Bitfinex users. It is built on the Ethereum blockchain and uses the ERC-20 standard.

As LEO is a key component of the Bitfinex ecosystem, it offers various benefits to its holders. Even though LEO was originally issued as a private token, later it became open for public trading on the Bitfinex exchange. Currently, the LEO token is used to pay trading fees on Bitfinex and provides holders with discounts on fees and other privileges. In addition, holding LEO tokens provides additional opportunities, such as participation in voting on strategic issues related to the exchange, and obtaining preferential terms when using other products and services of the platform.

Bitfinex has a LEO burn mechanism that provides for regular token decrease. Each month, Bitfinex allocates a certain percentage of its trading fee earnings to burning LEO so to decrease the total supply of the token. The LEO burn mechanism helps to maintain economic stability and the price of the token and aims to increase the value of LEO for its holders (since a decrease in supply can increase the demand for LEO). Thus, the more tokens that are burned, the more shares in the total supply that existing LEO holders receive.

LEO has received attention and recognition in the cryptocurrency community due to its association with the well-known exchange Bitfinex and is currently the 21st most popular cryptocurrency in the world. Its solid infrastructure and backing from a large platform make LEO one of the notable tokens in the crypto space.

This migration aimed to use the EOS blockchain's features for improved scalability and efficiency for LEO token transactions.
