On Tuesday, an address dormant since April 3, 2014, reactivated to transfer 300 bitcoin—valued at $31.06 million—for the first time in over 11 years.

Bitcoin Time Capsule Opens: 2014 Whale Wallet Transfers $31M

As bitcoin trades above the $103,000 mark, a number of long-idle coins have stirred back to life amid elevated prices. On May 13 at block height 896,546, a legacy P2PKH (pay-to-public-key-hash) wallet transferred its contents to a previously unseen Bech32 address, where they remain untouched.

The funds’ corresponding bitcoin cash (BCH) holdings, valued at $120,916, also lie dormant and untouched. When the 300 BTC were first acquired in 2014, the stash was worth $133,200, reflecting a 23,223% gain as BTC traded at $444 apiece. Per blockchain explorer Blockchair, the transaction registered a privacy score of just 45 out of 100.

Its confidentiality was further weakened by repeated use of the same address in the inputs and by employing the “send everything” option. This month has witnessed numerous revivals of long-dormant BTC addresses, with most of them harking back to 2013 and 2017. In May, just one other 2014-era address stirred, with 34.05 vintage bitcoin migrating from a 2014 wallet on May 5 at block height 895,558.

As of block 896,550, BTC’s circulating supply stands at 19,864,000.85. Approximately 17%—or 3,386,844.68 BTC—has lain untouched for more than a decade, while 30.62% (6,078,044.26 BTC) has remained static for at least five years. Furthermore, 1,767,638.28 BTC (8.90% of the supply) represent unspent block rewards, with over one million of those coinbase rewards dating back to 2009.
