A 2009 Bitcoin miner began transferring Bitcoin to the cryptocurrency exchange Kraken three weeks ago after nearly a decade of inactivity. So far, the wallet has transferred a total of 10 Bitcoins through three transactions, the latest of which was 5 Bitcoins sent on Tuesday. According to data from the on-chain analysis tool Arkham, the miner had transferred Bitcoin several times between 2011 and 2014, but then the account stopped being active. Recently, the frequent activities of such wallets from the "Satoshi era" have attracted market attention. (CoinDesk)
