BitMEX is an international cryptocurrency exchange that was launched in 2014 by HDR Global Trading Ltd. (Arthur Hayes, Samuel Reed & Ben Delo). This particular platform is cryptocurrency only, meaning that deposits and withdrawals via fiat wire transfers are not allowed – i.e. Bitcoin in-Bitcoin out only.
BitMEX offers margin trading, with leverage up to 100x on Bitcoin on the spot and futures markets. Leverage on altcoins varies and for now Bitcoin is the only cryptocurrency that offers the full 100x, with Ethereum offering up to 50x and Litecoin up to 33.3x
