PANews reported on May 20th that, according to Arkham's monitoring, Irish drug trafficker Clifton Collins purchased $30,000 worth of BTC between 2011 and 2012, now valued at $400 million, but he lost his private keys and is now in prison. These BTC were initially thought to be lost until a month ago when 500 BTC were transferred for the first time in 10 years. And just recently, another 500 BTC (worth $38 million) were transferred.
