I am just laughing when some people talking like this. My question to them is why they want to offer someone to sell these tricks? If they use it by ownself can earn a huge amount. And this man can crack private keys so he can get the all circulating bitcoin his own. what a joke!

Op it is a matter of sorrow that you have scammed. But unfortunately, the information you provided is not enough to prove the accusation. It would be better if you can provide more info. such as scammer profile link if you have, Your chat screenshots, etc.
