Bitfinex is a premier destination for seasoned traders all over the world and one of the top exchanges in terms of recognition and trading volume. It serves all except few countries in the world (mentioned below) and supports both fiat-to-crypto and crypto-to-crypto trades. Other notable features include margin trading, limit and stop orders, over the counter (OTC) trades, and others. While there are many options available, everything is laid out in an impressively intuitive fashion, with easy to navigate dashboards and menus. Yet despite the robust security measures, Bitfinex has been hacked twice (in 2015 and 2016). Since then it has significantly improved its security and compensated lost funds to every user.
