Regrettably, we cannot provide service to residents of New York due to the state's imposition of the "BitLicense." We hope this changes in the future, and we will notify you if and when it does.

In the meantime, you can still submit verification details to pre-verify your account. This will ensure account features are unlocked when and if this situation changes.

Thank you for your understanding. We truly hope to be able to provide service to you soon.
Best Regards,
