I was gunna leave a nice reply, but it's like talking to a brick wall
People can believe what they want to believe, fact is the BTC got stolen, I paid the price for it. Sometimes there are no conspiracies, or a grand plan to deceive, what is said happened, happened.
Unless the guy that stole them dares to come forward and announce it, and proves he did, you'll have to make up your own mind, because it's impossible to prove you don't own something.
