•Bitcoin small-value transfers surged to 39,600 BTC on August 2, 2026, post-Colcard incident.
•The increase in transactions is the highest since the FTX collapse in November 2022.
•Experts suggest that the Coldcard incident reflects issues with specific wallet security rather than self-custody failures.

The suspected hacking incident involving Coldcard wallets has led to a significant increase in small-value Bitcoin transfers, reaching levels not seen since the FTX collapse. On August 2, 2026, data from CryptoQuant revealed that approximately 39,600 BTC were transferred in a single day, just shy of the record set in November 2022. This surge has prompted discussions regarding the security of self-custodied Bitcoin. Julio Moreno, CryptoQuant's Head of Research, views the proactive measures taken by users as a positive development. Industry experts, including Eric Balchunas from Bloomberg, suggest that Bitcoin ETFs may offer a safer investment alternative due to their regulatory framework. However, the Coldcard incident appears to be more related to specific wallet security issues rather than a systemic failure of self-custody practices. The situation emphasizes the need for security awareness and risk management among Bitcoin users.
