Hello.
First thing first: i am the solver of Puzzle 66.
But i lost it soon as it was spend.
Sign a message with the first address that tried to withdraw puzzle 66 because I don't believe you, I think you're a scammer.
He IS a scammer. He shows no proofs. The original solver address is 1Jvv4yWkE9MhbuwGUoqFYzDjRVQHaLWuJd and there is no use to beg using any other address. Anyone can send to the proper address. The one who stole the fund was sending a mocking message to there. I don't think he is willing to send half of the stack.
