A UK court has sentenced the mastermind of the country's largest Bitcoin fraud scheme to 11 years in prison. The individual orchestrated a Ponzi scheme that defrauded victims of millions of pounds in cryptocurrency. Utilizing sophisticated digital tools and blockchain anonymity, the perpetrator managed to evade detection for an extended period. The case, which involved multiple countries, was cracked through international cooperation and advanced digital forensics. This sentence is one of the longest ever handed down in the UK for a cryptocurrency-related crime.
