Bitfinex is a major cryptocurrency exchange founded in 2012, operated by iFinex Inc. The exchange is registered in the British Virgin Islands and has historically been one of the largest platforms by trading volume, particularly for Bitcoin and Ethereum. Bitfinex offers spot trading, margin trading, derivatives, lending, and a peer-to-peer financing market across a wide range of digital assets.
Bitfinex is closely associated with Tether (USDT), the world's largest stablecoin by market capitalization. Both Bitfinex and Tether are operated under the iFinex corporate umbrella. This relationship has drawn regulatory scrutiny, including a 2021 settlement with the New York Attorney General over claims about Tether's reserve backing and commingled funds with Bitfinex. Despite controversy, Tether has grown to become a dominant force in crypto markets, and Bitfinex continues to operate as a significant exchange.
The exchange serves advanced traders with features including customizable interfaces, a wide selection of trading pairs, paper trading, and API access. Bitfinex has also invested in the broader ecosystem, supporting Bitcoin development through initiatives like funding open-source Bitcoin and Lightning Network projects. The exchange launched Bitfinex Securities, a regulated platform for tokenized securities, in El Salvador.
