The Bitfinex exchange is a popular platform for exchanging cryptocurrencies, also hosting spot and derivatives trading as well as certain lending, borrowing and staking features. Bitfinex came into existence in 2012. Bitfinex fees for spot trading are 0.10% for maker orders and 0.20% for taker orders. For derivatives trading, maker orders give customers a 0.02% rebate, while taker orders incur a 0.075% fee. Trading fees vary for each customer based on their trading volume and activity. Bitfinex also has its own utility crypto token called Unus Sed Leo (LEO). Because it restricts a number of regions, Bitfinex U.S. customers are not allowed. On Bitfinex, KYC and Anti-Money Laundering procedures are employed.
Back in 2016, there was a Bitfinex hack in which 119,756 Bitcoin (BTC) was stolen. Back then, 119,756 BTC was valued at about $72 million total.
