635 Dormant BTC Wake in September’s First Week, 500 Tied to a 2017 Whale

More than 9,000 dormant bitcoins moved in August after years of silence. September is now showing its own stirrings, with a slew of 2017 wallets waking and pushing the edge once more.

September Sees Sleeping Bitcoin Wallets Stir

Last month, 9,062 $BTC left vintage addresses, shifting onchain for either sale or consolidation. September is now showing movement, and on Sept. 4, 2025, btcparser.com caught 400 $BTC valued at $44.22 million shifted for the first time since July 2017.

The shift took place in two transfers, and the two addresses were created on July 30 and 31 of that year, when $BTC traded at $2,875 a coin. The funds moved from two legacy wallets into a group of newer Segregated Witness-compatible addresses.

Blockchair’s privacy tool rated the first transfer at 80 out of 100 on its privacy scale, with most deductions tied to repeated use of the same address in inputs. So far in September, eight dormant bitcoin moves have occurred, shifting a total of 635.64 $BTC worth $70.27 million from wallets created between 2013 and 2017.

The 2017 whale that moved 400 $BTC on Thursday also sent 100 $BTC earlier at block height 913139. That 100 $BTC came from an address first created on July 31, 2017. However, both this transfer and the other 200 $BTC send, had lower privacy scores than the one rated 80.

The 100 $BTC transfer scored a flat zero, flagged for matched and repeated addresses, while the 200 $BTC transfer scored 40 for similar discrepancies. Most of us veterans know old coins do not sleep forever. They wait until hands decide to wake them.

The numbers always tell their tale—quiet years, sudden shifts, and trails marked by scores. The chain remembers everything. Each move reminds the market that time does not erase value, it only waits for it to be claimed again. Ever since $BTC crossed into the six-figure zone, long-silent coins have been springing back to life.
