Funding financial institution Jefferies’ longtime “Greed & Concern” strategist Christopher Wooden has reportedly dropped Bitcoin fully from his flagship mannequin portfolio, citing mounting considerations that advances in quantum computing may undermine the cryptocurrency’s long-term safety.
In response to a report by Bloomberg, within the newest version of his Greed & Concern publication, Wooden stated the ten% Bitcoin (BTC) allocation he first added in late 2020 has been changed by a cut up place in bodily gold and gold mining shares.
He argued that quantum breakthroughs would weaken Bitcoin’s declare to be a reliable retailer of worth for pension‑model buyers.
Wooden added that concern over quantum threat is rising amongst long-term, institutional buyers, warning that some capital allocators now query Bitcoin’s retailer of worth case if quantum timelines compress.
He stated he feared that “cryptographically related” machines arriving prior to anticipated may let attackers derive personal keys from uncovered public keys, weakening the cryptography underpinning Bitcoin balances and mining rewards and, within the excessive, difficult its function as “digital gold” for pension‑model portfolios.
Quantum threat enters mainstream portfolios
The quantum problem has been mentioned for years amongst builders and commentators, however Wooden’s transfer reveals the way it’s now influencing mainstream asset allocation selections at main brokerage and analysis homes.

Fortress Island Ventures companion and Bitcoin advocate Nic Carter has mentioned the quantum problem at size, warning in December that “capital is worried and searching for an answer” on quantum threat, despite the fact that many builders, resembling Blockstream CEO Adam Again, stay skeptical that it’s a close to‑time period downside.

Macro analyst Luke Gromen has additionally turned cautious on Bitcoin in current months, citing macro and technological uncertainties, together with quantum computing threat, as causes to favor rising gold publicity versus BTC on a multi‑cycle view.
Research from companies resembling EY and PwC equally flag quantum computing as a big rising risk to conventional public key cryptography, warning that monetary methods, together with these supporting digital belongings, want to organize migration paths to quantum-resistant alternate options.

Builders say Bitcoin has time to adapt
Bitcoin builders and core infrastructure builders push again on the concept that quantum progress is a right away risk.
Blockstream CEO Adam Again has repeatedly argued that breaking Bitcoin’s present signature schemes is probably going 20–40 years away and that the community would have ample time emigrate to put up‑quantum signature algorithms and higher key administration practices effectively earlier than any actual‑world break turns into possible.
Different analysts, together with an a16z researcher, equally conclude that the chance of a “cryptographically related” quantum laptop able to breaking right now’s public key methods rising this decade is low.
They are saying that the larger close to‑time period dangers come from implementation bugs, governance, and “harvest now, decrypt later” assaults on encrypted knowledge fairly than rapid assaults on stay blockchain signatures.
