2013 Bitcoin Whale Spotted as Coldcard Fears Drive Dormant Wallets to Move

A significant transfer of $500 BTC from a dormant wallet created in 2013 has been flagged, highlighting concerns over security amidst the Coldcard exploit.

The transfer was first reported by btcparser.com and Whale Alert, with blockchain explorer data showing the original Pay-to-Public-Key-Hash (P2PKH) address was created on December 6, 2013. At that time, bitcoin had just broken above $1,000 for the first time.

The wallet's 500 BTC stash would have been worth around $521,000 when it was originally acquired in 2013, but today it is worth over $31 million. The receiving address is not tagged as any known exchange, custodian, institution, or other identifiable entity.

For early bitcoin adopters, a wallet untouched for more than a decade represents far more than just a balance, it reflects a decision made in 2013 to prioritize self-custody and exclusive control over their private keys. The Coldcard firmware flaw cuts directly against this philosophy, threatening the security of these users' wallets.
