Irish drug dealer's bitcoin address transfers another 500 BTC

According to ChainCatcher, monitored by Arkham, Irish drug dealer Clifton Collins purchased 30 thousand dollars worth of BTC between 2011 and 2012, which is now valued at 400 million dollars, but he lost the private keys and has been imprisoned. These BTC were once considered lost until a month ago, when 500 BTC were moved for the first time in 10 years. Just recently, another 500 Bitcoin (worth 38 million dollars) were transferred.
