Authorities are investigating a cryptocurrency scam known as 'pig butchering,' which has defrauded U.S. victims of $4 billion. Victims from the Bay Area have reported losing their life savings, with some perpetrators also being victims, kidnapped and forced to participate in the scam. Shai Plonski, a scam victim, recounted being persuaded to invest by someone who seemed trustworthy. The scam has had severe financial impacts, including an elderly widow losing her life savings and an 83-year-old retired government official losing Rs 2.5 lakh. The public is urged to remain vigilant and verify investment opportunities to avoid falling prey to such scams. Aaron Katersky is investigating the issue.
