BitMEX has rigorous checks and balances in place to secure the funds of its users. It introduced a powerful cryptographic tool called multi-party computation (MPC), which ensures that your funds are secure even if all of BitMEX's system is compromised. The company employs at least two BitMEX experts who audit every Bitcoin withdrawal by hand before sending. Also, the deposit addresses on BitMEX are all verified by an external service. Its aim is to check if the addresses have the same keys that are controlled by the founders because if not, then the system is pulled down.
