Bitfinex is an exchange present in the cryptocurrency landscape since 2012 owned and operated by iFinex in Hong Kong. The volumes are very large, which makes it a strong place for cryptocurrency trading. In addition to allowing transactions in fiat currency (USD, EUR, GBP, JPY ...), it also allows many other more specialized transaction options including limit and stop orders, margin operations and loans, and over-the-counter transactions (OTC, etc.). Although there is a wide choice of options available, everything is designed intuitively and it is very easy to navigate through the platform. The exchange supports more than 116 trading pairs with a daily volume of more than 5900 BTC. Unfortunately, Bitfinex was the victim of a massive theft of 120,000 BTC in 2016. It has since recovered and represents one of the best trading platforms on the web.
