According to ZachXBT, prosecuting crypto-related fraud cases faces several challenges. These include the need for clear and irrefutable evidence to succeed in court, the general indifference towards influencers involved in pumping and dumping meme coins, and the lack of concern for undisclosed promotions. Furthermore, the complexity of dealing with multiple jurisdictions and the scarcity of law enforcement skilled in cryptocurrency matters complicate the situation. Additionally, if minors are involved, law enforcement's involvement is reduced. (Source)
