BitMEX is a cryptocurrency derivatives exchange. The BitMEX exchange offers a Bitcoin (BTC) perpetual swap trading product, which allows participants to leverage up to 100x the funds they hold on the exchange. Additionally, on BitMEX, BTC futures contracts that come with expirations can be traded, as well as futures and perpetual swap trading for crypto assets other than BTC. BitMEX fees and the BitMEX funding rate come with trading on the platform, depending on the contracts traded.
BitMEX also has a simulated trading platform, called BitMEX Testnet, on which participants use a worthless digital asset called Testnet Bitcoin. BitMEX does not allow customers from the United States and a number of other regions.
