Strive's Joe Burnett proposes custody solution after after 'worst week in Bitcoin history'
Strive’s VP of Bitcoin strategy, Joe Burnett, said the prior week was among Bitcoin’s worst, citing a firmware exploit that led to about 1,082 BTC (around $70 million) being stolen from Coldcard hardware wallets. Burnett urged large holders to use institutional custodians over self-custody. Coldcard maker Coinkite shipped the flawed version in 2021 and later patched it.
How this was made

The 30-second read
Why it matters
The key trading takeaway is a shift in custody risk framing: self-custody can fail via device/firmware randomness issues, while institutional custodians are positioned as reducing single-point-of-failure risk.
Market read
Custody security concerns and institutional-custody advocacy may influence sentiment and flows, but the article provides no new Strive-specific financial catalyst.
What to watch
The article does not quantify how many users were affected, nor does it provide evidence of broader systemic wallet failures beyond the cited firmware version.
Background
Strive’s VP of Bitcoin strategy argues that the prior week’s losses were driven by a Coldcard firmware exploit and weak seed randomness, even when users followed recommended procedures.
Ticker impact
Strive is described as a Nasdaq-listed Bitcoin holder trading under the ASST ticker, with 20,000 BTC valued near $1.3B.
Limited direct impact on ASST from this piece alone; any effect would be sentiment-driven around custody risk.
No new Strive-specific financial disclosure is provided, only a VP quote and general custody guidance tied to a Coldcard firmware exploit.
Market effects
Highlights operational and firmware-seed randomness risks in self-custody hardware wallets, potentially increasing demand for institutional custody solutions.
No clear regional market linkage beyond US-listed Strive mention.
Custody and wallet security concerns can affect global retail and institutional sentiment toward self-custody practices.
Counterpoint
Bitcoin price is said to have stayed near $63,000 despite the theft, suggesting the event may not materially change BTC’s risk premium.
