A long-dormant Bitcoin whale has resurfaced, moving funds untouched since 2012.

On Sept. 11, blockchain tracker Lookonchain revealed that three connected addresses shifted 137 BTC, worth about $15.6 million, out of a cache of 955 BTC (equivalent to $108 million).

According to the firm, a small portion of the funds, 5 BTC, was sent to Kraken, suggesting an intent to sell.

Notably, the addresses were last active when Bitcoin traded at just $12 per coin, leaving their combined balance valued at around $10,000 at that time.

However, with BTC price near $113,000 as of press time, that same stash is currently worth more than $108 million, according to CryptoSlate’s data. This represents a gain of over 10,000% in just over a decade.

Dormant Bitcoin wallets resurface

This movement fits into a recent trend of long-dormant Bitcoin wallets reawakening after several years of inactivity.
