A Bitcoin address dormant for more than 13 years became active Sunday, sending a transaction worth $43, which has the shape of a test before something larger. The wallet accumulated 801 BTC when Bitcoin traded between $124.86 and $411.75, leaving unrealized profit near $67.82 million at current prices. Odaily Planet Daily reported the movement. Nothing further has moved yet, and a test transaction is not a sale, but wallets of this vintage draw attention because the holder has sat through every cycle since 2013 without selling.
