Obtained from a fraud? Do you mean btc? or those people do hackings, scam, etc? If do you mean btc, well btc isn't a fraud and you can be proud of it if you became rich by bitcoin. You obtained it because of your hardwork, as long as you didn't do anything fraudulent, no matter what other says about crypto.
The OP post is confusing but he's definitely not talking about bitcoin to be something like fraud which I believed was the reason why he said if the "success were obtained fraud." Which he's was talking about those that abuse the crypto system to scam people. However, I believe the OP still need to understand some rules and about this forum due to some of his few posts.
