Robert M Faiella, the bitcoin trader charged alongside BitInstant CEO Charlie Shrem, has been sentenced to four years imprisonment in New York.
Faiella, otherwise known as 'BTCKing', pleaded guilty to operating an illegal money transmission business after he exchanged fiat currency for bitcoins that were then used to buy drugs on the Silk Road marketplace.
Faiella, a 53 year-old Florida native, is a former plumber who claimed he had turned to the bitcoin exchange business to support his family after becoming disabled with back problems. He and Shrem were arrested in January 2014.
Sentenced by US District Judge Jed Rakoff, who also presided over Shrem's case, Faiella faced a five-year maximum term.
Shrem himself was sentenced in December to two years in prison after making a plea deal with prosecutors. While currently living at home, he must surrender himself at a date yet to be determined and any travel prior to that needs to be approved by a judge.
He was not able to obtain permission to attend the recent North American Bitcoin Conference in Miami.
Shrem also admitted his actions had broken the law, and said his sentence was light considering the 30-year maximum he had faced, and up to 60 months even with the plea bargain.
He also had to forfeit $950,000 in profits and will have three years of supervised release after his sentence is complete.
Ross Ulbricht, accused of being the ringleader of the Silk Road operation called 'Dread Pirate Roberts', is currently on trial for drug trafficking, money laundering and computer hacking in New York.
Ulbricht has not made a plea deal and faces life in prison if found guilty.
