Well the problem is it requires Signed message, which i don't have
And i don't the access to the wallet that i used in 2013 anymore, i lost interest on bitcoin at that time and forgot about it
Any other suggestion Mitchell?
No. Signed message is the best and quickest way to proof ownership.
I very rarely recover accounts if you can't prove ownership as described above. There are alternative ways of proving ownership, but they take too much time.
