This guide will provide details on the UNUS SED LEO cryptocurrency token, a utility token created to be used on Bitfinex and other iFinex trading exchange platforms. iFinex Inc. is a private organization incorporated in the British Virgin Islands, managing cryptocurrency exchange platforms under the Bitfinex business name.

1 billion USD was reportedly raised from the UNUS SED LEO token sale on May 2019 with the tokens issued to participants across Ethereum and EOS network in a unique dual blockchain protocol launch. The purchase price for buyers was 1 UNUS SED LEO for 1 USDt and the tokens were issued from UNUS SED LEO Limited, a newly-formed subsidiary of iFinex. Tokens were reportedly not sold in the United States and to U.S. citizens due to regulations. The total supply of UNUS SED LEO tokens is fixed at 1,000,000,000. A LEO:USDt trading pair is now available on the Bitfinex market exchange for peer-to-peer trading.


The company motto of Unus Sed Leo is from an Aesop’s fable Latin quote, “The Sow and the Lioness”. The story narrates on how a sow loved to show off the number of children she had, and when she asked the lioness how many children she had, the lioness replied “One, but a lion.” The iFinex team selected the above motto to showcase the spirit of quality over quantity.
