Forum and BPIP website will detect this change and some members may think that there has been some account ownership change or account selling, so my question is what would be the best way to make this change?
The forum would give warnings like:
user recently changed their email
user recently woke upThe purpose of these warnings are to serve as a heads up, and not a prove that the account has changed hands. Any suspicion would need to be fueled by more actions
Maybe making this post in advance like I am doing now would be enough to prove that I am still the same owner, and password change is more common as I noticed that many old members including theymos changed their passwords several times.
PS
I can also prove ownership for staked Bitcoin address.
This post is ideally enough to quell any suspicion that would arise from a change. You can also sign an address and include a change in email as the message.
