A 2009 bitcoin miner began transferring bitcoins to cryptocurrency exchange Kraken three weeks ago after almost a decade of account silence. So far, the wallet has transferred a total of 10 bitcoins in three transactions, the latest of which was sent on Tuesday. According to data from on-chain analytics tool Arkham, the miner transferred bitcoins several times between 2011 and 2014, but then the account stopped moving. Recently, such wallets dating from the "Satoshi era" have attracted the attention of the market.
