First and foremost, users must register for an account on the BitMEX website. There is no KYC process when signing up on BitMEX, but you’ll need a genuine email address. The minimum age is 18. Also of note, BitMEX does not accept registrants with US-based IP addresses, leading US users to bypass this by using a VPN during the registration process. Once registered, the US users have reported there being no need for a VPN when using the exchange after signing up.
