A UK court has sentenced a gang of 12 individuals to a combined 88 years in prison for running a £4.6 million ($5.2 million) drug operation and laundering profits through Coinbase. The gang's leader, Amir Khan, converted £1.65 million ($2.1 million) of the funds into cryptocurrency, making it difficult to recover some of the funds. One of Khan's co-leaders, Joshua Billingham, received a 14-year, eight-month sentence, while Stacey Challenger, who laundered £300,000 and conspired to turn it into cryptocurrency, received just one year in prison. The case is one of the first in Gwent where cryptocurrency was used to launder money.
