Massive Bitcoin Transfer in 25 Minutes Nets $38M

A massive Bitcoin transfer occurred on Thursday, with approximately $38 million worth of cryptocurrency moved in just 25 minutes.

The funds were transferred from 500 single-signature addresses to a new wallet, valued at around $38 million. The affected holdings all used single-signature addresses with balances ranging from about 0.15 to 0.26 BTC, and many UTXOs had remained dormant for years.

Coldcard CEO NVK denied any device-wide vulnerability, stating that the user may have imported a seed that was previously leaked or compromised. Jameson Lopp pointed out that another victim only lost part of their UTXO, not the entire wallet balance, which may indicate that only individual private keys were exposed rather than a complete seed leak.

The coordinated transfers are confirmed, but the source remains unknown. There is currently no evidence of a Coldcard RNG flaw, supply chain vulnerability, or a Bitcoin cryptographic failure.
