Hi I signed a message confirming who I was but nothing happened
Just said signing was successful. I put that I was Britainacoin from Bitcointalk as the message and got a huge long random letter "signature", it said signing was successful then nothing happened lol.
and what you had expected? I suggested you sign message to prove that you still same owner of this account, but this is problematic since I check you post history and did not found any staked btc address, and you trade history without reference.
