The recent $89 million Coldcard hardware wallet exploit is reshaping Bitcoin holder behavior in a way not seen since the FTX collapse of late 2022. According to on-chain data cited by CoinDesk, daily exchange deposits of Bitcoin valued under 10 BTC surged to 7,300 BTC on Friday – the highest level since February 6. This wave appears to be driven by smaller holders seeking the perceived safety of centralized platforms after the vulnerability in the popular Coldcard hardware wallet came to light.
The Shift from Self‑Custody to Exchanges
The flow of coins back to exchanges marks a stark reversal from the post‑FTX era, when massive withdrawals drained centralized platforms as users rushed to take custody of their own funds. This time, the trigger is a hardware wallet flaw rather than exchange failure.
