Do you have a signed message and could you specify the exact end time and in what timezone?
can OP answer that question? I didn't think of that because this is the first time I'm buying an account.
What u mean with Signed message? time is europe(paris)
Signed Message means Signed Message. you sign a message from a bitcoin address that was posted by that account at least 2-3 months ago to prove your ownership of that account.
if a person wrote in the message your bitcoin address he hacker? sorry maybe I did not understand. Could you give an example of such a message?
