100 BITCOIN FROM JULY 2010 MOVED ON OCTOBER 7 — THE ADDRESS HAD SPENT IN 2011 — ITS PUBLIC KEY SAT ON THE CHAIN FOR 15 YEARS

On July 30, 2010, at block 71,217, an address beginning 1J3A7Hov received 100.02 bitcoin. At 18:52 UTC on October 7, 2026, in block 970,379, the coins moved. One transaction: the 2010 coins plus six dust inputs, a fee of 1,467 sats. They went to two new SegWit addresses, 10 bitcoin to one and 90.02 to the other. Neither has spent since. CoinDesk puts the value at about $8.5 million.

These were not untouched coins. The address first spent on June 16, 2011, at block 131,207, and it spent again over the years, most recently on March 17, 2018. A pay-to-public-key-hash address keeps its public key hidden behind a hash until it spends. The first spend put this one on the chain. It stayed there for 5,592 days, about 15.3 years, guarding the coins that were left.

That is the case Europol’s October 7 report pointed at when it called wallets “the primary point of exposure to quantum threats.” Here is one, on the record: a readable public key over 100 bitcoin for 15 years, and the coins moved only when someone holding the private key signed. As of this writing they sit at two addresses whose keys are still hidden.

Everything above can be checked on any node. Who signed, and why, cannot. CoinDesk says it plainly: “Their age does not establish a connection to Nakamoto.” We are not guessing at the owner or the motive. The chain says a valid key signed. That is all it says, and it is enough. At the time of this writing, bitcoin was $82,455.
