first of all i am sorry for the lost. but did anybody here asked op to sign a message to prove the ownership of the address? it's important right to claim that the address is really owned by op. and after that we can go discussing this . no offense op okay

No, why? They can hardly reclaim the coins with a signed message. I dont see how that matters at all.
I think he means to say that we should first actually get some proof that OP's wallet was indeed hacked and he is not just wasting everyone's time with wild speculation as to how his wallet might've been hacked
