25-year-old Matthew Yensan, from North Carolina, was sentenced to 78 months incarceration today for producing Xanax and Alprazolam, selling them on the darknet and laundering the proceeds of crime using, inter alia, Bitcoin and Litecoin.
According to the indictment, Yensan had a Glock 27 .40, a Smith & Wesson Revolver .357, a Colt King Cobra Revolver .357, an MP-5.  All the guns were loaded. Agents also located a Trezor with 182 Bitcoin and two other cold wallets. Under his bed, agents found US$300,000 in cash.
After Yensan was indicted, DEA agents later located additional digital currencies – about double the original amount.
Yensan had posted a note on Facebook that he was thinking of using Bitstamp as his digital currency exchange, which is an unusual thing to do if one is a drug trafficker.
Apparently, the government has not located additional Bitcoin Cash and Ether held by Yensan.
