According to data provided by Whale Alert, a Bitcoin wallet containing 407 BTC ($15.5 million at press time) has been activated for the first time since 2013.
The coins were initially worth $355,254, which means that they have appreciated roughly 4,266%.
Bitcoin is currently trading at roughly $38,000 on major spot exchanges.
Over the past few months, several similar Bitcoin wallets came to life after years of inactivity. Addresses that date back all the way to 2011 typically attract the biggest amount of public interest since they could be possibly linked to none other than Satoshi Nakamoto.
Meanwhile, a dormant Ethereum wallet containing more than $5 million worth of ETH awoke in late February.
