William Panzera was sentenced to 12 years in prison for involvement in international drug smuggling using Bitcoin as an intermediary. Between 2014 and 2020, over a ton of synthetic opioids and fentanyl were transported from China to New Jersey, and Panzera paid Chinese suppliers in Bitcoin during the process. This case exemplifies how digital assets are being utilized within large-scale illegal drug networks. The pseudonymous nature of cryptocurrencies makes them difficult to trace, which criminals like William exploit, highlighting the increasing challenges faced by law enforcement agencies.
