Coldcard exploit could boost demand for regulated bitcoin exposure, analysts say

The Coldcard wallet exploit, which saw investors’ bitcoin BTC$64,628.65 drained from their cold wallets, highlights the risks some investors face with self-custody and could bolster demand for spot exchange-traded funds (ETFs) and be positive for some crypto-related equities, according to Wall Street analysts.

Investment bank Cantor said the breach may reinforce the appeal of publicly traded crypto firms linked to institutional adoption.

The bank said the exploit could drive Coldcard users toward managed custody providers, potentially benefiting firms including Robinhood Markets (HOOD), Coinbase Global (COIN), BitGo Holdings (BTGO), Bullish (BLSH), eToro Group (ETOR) and Gemini Space Station (GEMI) through increased customer inflows.

“The read-through is second-order but we would expect that token flows to custodians and exchanges will increase following the hack,” Nico Pasquariello, a digital asset specialist, said in the Wednesday note to clients.

The exploit allowed attackers to steal bitcoin from users who had opted for self-custody, underscoring that holding one’s own private keys still requires trust in the hardware and software used to generate and manage them.

The exploit, which researchers say stemmed from a flaw in the wallet’s firmware, has resulted in at least 1,816 bitcoin, worth about $114 million, being drained from more than 5,200 addresses since July 30, underscoring the risks even self-custodied assets face when wallet security is compromised.

FRNT Financial echoed that view, saying the exploit exposed a key tradeoff in self-custody. While many bitcoin holders prefer to control their own assets, they still place their trust in the hardware and software used to generate private keys.

“The reaction within the BTC community to the exploit was one of heartbreak,” FRNT wrote in a Wednesday report, noting many affected users had followed long-standing best practices around self-custody.

The firm compared the incident to the 2023 “Milk Sad” exploit, in which flawed key generation led to the theft of roughly $900,000 in digital assets. Rather than undermining self-custody altogether, FRNT said it expects the latest breach to spur wallet providers to strengthen their products as users demand greater security assurances.

For investors unwilling to accept the operational risks of managing private keys, the growing availability of spot bitcoin ETFs provides an increasingly attractive alternative, FRNT said.
