Your ability to purchase and spend tokens is temporarily suspended as a precautionary measure when we notice a suspicious activity in your account.
In such instances, you will have to verify your account by either verifying your card or uploading your documents. Make sure to also check your email or private messages, since you will find detailed instructions there on how to revert your account to full functionality.
Remember that you can always contact our Customer Support should you have any doubt or need further assistance.
