A Bitcoin wallet created on Dec. 6, 2013 moved 500 BTC on Monday, sending $31.32 million at block height 960867 after sitting untouched for more than a decade. The transfer came from a long-dormant address that had been worth roughly $521,000 when the coins were first acquired.
The move matters now because dormant Bitcoin wallets moving funds has become a live market story again as the Coldcard exploit keeps pushing old holdings into motion. More than 1,400 BTC has already been swept through the exploit, with an estimated 1,431.97 BTC stolen, and the latest transfer adds another large 2013 stash to the list.
The timing also lines up with a broader shift in behavior. Bitcoin.com News reported on Aug. 1 that the Coldcard exploit appeared to be driving bitcoin holders toward centralized exchanges and custodians, after the breach first surfaced on July 30. In the days between July 30 and Aug. 1, 306 BTC from long-dormant wallets moved, suggesting that the security scare has reached wallets that had not stirred in years.
But this transfer does not fit neatly into a simple flight-to-safety narrative. Arkham Intelligence showed the receiving P2WPKH address was not tagged as any known exchange, custodian, institution, or other identifiable entity, leaving open whether the owner was moving funds defensively, parking them temporarily, or simply sending them to another private address. The first flag came from btcparser.com and Whale Alert, but neither service identified the destination as a mainstream venue.
At the end of 2013, 1 BTC was changing hands at $1,042 per coin, which means the wallet’s 500 BTC hoard was worth about $521,000 when it was originally acquired. On Monday, the same coins were worth more than 60 times that amount, a reminder that old Bitcoin can still surface with staggering scale when a long-unused address wakes up. ZachXBT has said he has no plans to trace the $88.6 million Coldcard hack, telling followers that Bitcoin’s community should not expect him to chase it down.
What remains unresolved is simple and central: the blockchain shows where the 500 BTC went next, but not why a 2013 wallet moved now. Until that is clear, the transfer reads less like a routine reshuffle than another sign that the Coldcard fallout is still reaching deep into Bitcoin’s oldest holdings.
