Bitcoin trades at 28% quantum discount as price slips near $62K

Bitcoin's latest slide has resurfaced an old debate dressed in new numbers. Capriole Investments founder Charles Edwards now pegs Bitcoin's "quantum discount" at 28%, arguing the market is pricing in fear over slow post-quantum security planning. His model compares Bitcoin's spot price against a projected $120,000 fair value path. After a sharp selloff, Bitcoin traded near $62,099, sitting below Edwards' discount line and widening the gap to his estimate. He points to developer inertia around quantum-resistant upgrades as the main issue, claiming Bitcoin Core hasn't moved quickly enough on post-quantum signature planning.

Quantum threat debate grows wider

Quantum computing could eventually threaten Bitcoin if future machines crack the elliptic curve cryptography protecting wallets. Today's systems hold up against normal computers, but quantum systems may rewrite that assumption over time. As crypto.news previously reported, Citi warned Bitcoin faces an outsized quantum threat, estimating 6.5 million to 6.9 million $BTC may already have exposed public keys on-chain. Quantus has separately suggested quantum timelines may be moving faster than earlier expected, noting that lost wallets could become a hard problem because their owners cannot move coins to safer addresses. Stanford cryptographer Dan Boneh offered a more careful view, telling crypto.news: "Don't panic, but don't ignore," while warning that a rushed migration could create its own technical risks.

Price model points to a widening gap

Edwards said the probability of a major quantum break, often called Q-Day, may begin rising after 2027 and could rise sharply by 2030 if Bitcoin lacks a clear upgrade plan. His argument is not that Bitcoin is already broken. Instead, he suggests markets may be discounting $BTC because investors see no official post-quantum migration roadmap. The model's discount factor implies Bitcoin may struggle to reach new highs without clearer developer action, and Edwards said a formal upgrade plan within 12 months could help close the valuation gap. That claim remains one market model, not a confirmed price rule, and Bitcoin still moves on many forces, including liquidity, ETF flows, macro stress, and leverage.

Treasury risk adds another concern

Edwards also pointed to Bitcoin treasury firms as another pressure point, citing the risk of debt-heavy strategies linked to corporate $BTC buying. The concern centers on firms that use capital markets to acquire Bitcoin at scale, with Strategy remaining the largest and most-watched example because of its long-running Bitcoin treasury plan. As crypto.news recently reported, Bitcoin was already under pressure from Iran-linked market stress and ETF outflows, with the same report noting Strategy sold 32 $BTC for about $2.5 million — its first sale in nearly four years. Bitcoin's next move may depend on whether buyers defend the $60,000 region. If $BTC stabilizes, the quantum debate may become a longer-term valuation issue. If selling continues, traders may watch whether technical pressure and security concerns feed the same bearish narrative.
