And this ensures me that, you actually never singed any address and stacked it in the Stake your Bitcoin address here. In this case it will be very hard (almost impossible to prove) for you to recover your hacked account.
One tiny hope could be...
If anywhere you posted any BTC address from your hacked account then find it. Tell someone to quote it to secure the address so that the hacker can not remove it completely, also take an archive.is snapshot as well. Then find a way to sign that btc address and finally try to convince any mod or admin to recover your original account.
cyprus? I remember
I figured out how to do the signing thing before i sent either of them a message and used the proper format when messaging then.
Ill try messaging them once more
