Why the hell would anyone even pretend to have a crypto fortune on social media in the first? My first guess would be to deceive people into believing what's not true, maybe to scam people or maybe not, but if not for anything, I'd say that serves him right and that he actually deserved what he got. At least that'll teach him to keep his mouth shut about his crypto holdings, maybe when he eventually manages to accumulate crypto in the future.
Not just him, this should serve as a lesson to people who go around bragging about their crypto holdings, even though some of them are actually telling the truth.
