Is it possible to change Stake username? or possible to transfer account to a new one, with the old stats? I think I had asked the customer support long time ago and they said it wasn't possible. Just wanted to check here if anything changed.
I haven't tried changing mine but I think they allow users to change their usernames, but the process isn’t automatic. Try to contact their customer support team directly. Make sure to provide your current account details, such as your existing username and email address, to verify your identity. Once they confirm your request, they can assist you in updating your username
Also, I found this link posted just recently, you can follow this and see if they will allow to change your username.
