Approximately 233,000 bitcoins were transferred for hedging, with Coldcard involved after an attack amounting to about 15 billion dollars

After the Coldcard hardware wallet firmware vulnerability was exploited, approximately 2,100 bitcoins were stolen, resulting in a loss of nearly $130 million. On-chain data shows that long-term holders transferred about 233,000 bitcoins from their wallets in the days before and after the incident, worth approximately $15 billion.

Casa CEO Nick Neuman stated that some of the transferred funds came from Coldcard users migrating to multi-signature wallets, and Ledger and Trezor users also took similar measures after the incident. During the same period, about 22,000 bitcoins were transferred to exchanges. Coinkite has requested that users who generated recovery phrases using firmware versions 4.1 to 4.1.9 consider the related wallets compromised and immediately migrate to new recovery phrases. The aforementioned versions cover from March 2021 to July 2026.
