It was a private key, i found it in a forum.
A private key forgotten 6 years on a public forum and nobody took it?Yes, this is unbelievable. If OP has already taken the bitcoins and moved to another wallet, it would be a good idea that he shows the link to that alleged forum where he found the private keys to believe his story.
More than knowing the forum he found the private keys you also want it like we do
don't you Anyways i have the doubt too about this post that it has really happened with the op or not.
I also think he should provide a proof.
