The claim in the original comment that I replied to was that Hans had admitted to cheating in "real, official, prize money online tournaments", which was when he was 12.
As for cheating and stakes I think it all depends. His claim is he cheated when he was 16 to boost his rating so he could player higher level opponents on stream and boost his career. If you accept that claim it would make sense that he rationalized it that he was just cheating to get to his "true" Elo and stopped cheating once he got there. Now Chess.Com seems to believe that he cheated beyond that but they haven't specified more at this point.
