We are required to hold it by law since your profile indicates you’re either a U.S. citizen or a U.S. resident. Without an SSN, we can’t issue your 1099 Tax Form, which you’ll need for your annual tax filing.
If you are no longer a citizen or resident of the United States, please contact our support team who’ll be happy to help.
Every cryptocurrency platform operating in the United States will ask for your SSN if you’re a U.S. citizen or resident.
