BitFinex offers three main functions – it is a pure bitcoin to fiat exchange, a margin trading exchange and a liquidity provider. The platform offers a number of features available that expand the financial positions you can take – for example the ability to short Bitcoin via margin trading.
The exchange also offers a set of other cryptos apart from bitcoin such as Litecoin and Ethereum.
Deposits and withdrawals take place via the standard bank transfer means with fees of 0.1% and a minimum of $20. Bitcoin and Litecoin are free.
