🚨 Over $500,000 in unrealized gains on bitcoins purchased at $14 in 2011. The address remained completely inactive for 15.1 years before transferring all 8.54 BTC in a single transaction on August 16, recorded in block 962,770. The amount moved is worth approximately $538,000. Galaxy Research found no public attribution linked to this address; the owner’s identity remains unknown. Such awakenings are tracked using Coin Days Destroyed, an indicator that accumulates the age of each bitcoin as long as it remains unmoved, then resets abruptly when an old balance changes hands. A spike in this indicator does not necessarily indicate selling—simply transferring funds to a more secure storage location produces the exact same signal.
