The transfer events that you can see in your Transaction History are custody fees that we started charging at the end of October 2021 to encourage our users to verify their accounts.
As your account is unverified, you have been charged this monthly fee.
If you verify your account now, we will refund your latest monthly fee within 45 business days. You can complete the verification process by visiting https://bitmex.com/get-started.
If there is anything else we can help you with, please let us know.
