Anthony Pompliano, investor and podcast host, told Bitcoin.com that a spot Bitcoin exchange‑traded fund (ETF) is “the single most secure thing” for anyone holding between $10,000 and $10 million in BTC. His comment directly challenges the long‑standing “not your keys, not your coins” mantra that underpins the crypto community’s preference for self‑custody. Pompliano’s remarks come as U.S. spot Bitcoin ETFs have recently experienced a $1.28 billion outflow, and they arrive amid a spate of hardware‑wallet security breaches that have raised fresh concerns about the safety of cold‑storage solutions.

Why Pompliano Prefers ETFs Over Cold Storage

According to Pompliano, the primary risk for large‑scale Bitcoin holders is the loss of private‑key material—whether through a misplaced seed phrase, phishing attack, or a counterfeit device. He argues that a regulated ETF eliminates those user‑error vectors by placing custody with a professional custodian, thereby converting a private‑key risk into a counterparty risk that is overseen by financial regulators. The BlackRock iShares Bitcoin Trust (IBIT), which relies on Coinbase as its sole custodian for roughly 815,000 BTC, is cited as the benchmark product in his assessment. Pompliano contends that, for investors whose chief concern is protection against loss, the institutional safeguards of an ETF outweigh the control afforded by self‑custody.

Hardware‑Wallet Turmoil Raises Questions

The timing of Pompliano’s comments coincides with a series of high‑profile incidents affecting hardware‑wallet manufacturers. Trezor warned customers about a malicious implant discovered in a Safe 5 device sold by a former reseller, a problem linked to a $93 million Ledger security scandal involving the same distributor. Keystone announced the destruction of 18,835 wallets after attackers compromised the verification key used to certify genuine devices, while Foundation’s Passport suffered a customer‑data breach. In a related physical‑security incident, investor Evan Luthra reported that masked assailants forced their way into his car in Oxford, stole over $2 million in crypto, and highlighted the tangible risks of hardware‑wallet ownership.

Critics Highlight Concentration and Use‑Case Limits

Despite Pompliano’s security argument, critics point to the concentration risk inherent in a single custodian model. Onekey founder Yishi Wang warned that North Korean hackers could target BlackRock’s IBIT, given its reliance on Coinbase for custody of a large BTC pool. Coinbase counters that over 99% of its institutional assets are stored offline, but the concern remains that a breach could affect a substantial portion of the market’s supply. Moreover, ETF shareholders cannot move their Bitcoin on‑chain, use it for payments, or trade outside market hours, limiting the utility of the asset. Peter Schiff highlighted this restriction in October, noting that ETF investors cannot sell during weekends, potentially exposing them to price gaps.
