it's just a security feature in case someone hacked your account and tried to change the email address. It helps lock them out of your account.
I read a few topics/FAQs here, and noticed you need to sign with a crypto address which you had on your account.
The thing is, I've never posted a crypto address here nor have I got one linked on my account.
a staked bitcoin address is necessary, but not mandatory. The recoveries team is flexible.
What I do have though is:
- Access to the registration email and current email
- Full access to the service/site I sell here (
https://bitcointalk.org/index.php?topic=5411315) - Perhaps I could add a signature on the website?
- On the same ISP (but different IP) as registration
This is more than enough. The original email address and they will also probably try to check the IP logs to be sure they are coming from a similar location
Good luck.
