- Approximately 3.5–4 million BTC (18% of supply) are dormant; fears are rising that quantum breakthroughs could crack legacy P2PK wallets, flooding the market with “zombie” coins.
- Developers have officially merged BIP 360 into the repository, introducing “Pay-to-Merkle-Root” (P2MR) to shield Taproot addresses from long-exposure quantum attacks.
- Despite “Quantum FUD,” institutions have absorbed nearly 3 million BTC since 2020, providing a massive liquidity buffer that prevents structural market collapses.
Bitcoin’s supply distribution paints a revealing picture of the cryptocurrency’s ecosystem. According to recent on-chain analytics, the total circulating supply stands at around 20.34 million BTC, with 0.66 million yet to be mined. The largest slice, 8.63 million BTC (about 42%), is held by retail and other investors, underscoring the decentralized nature of the network.
Lost and dormant coins account for 3.50 million BTC (17%), followed by exchanges holding 2.30 million in custody (11%). Miners’ treasuries control 1.80 million (9%), public and private companies 1.40 million (7%), ETFs and funds 1.30 million (6%), and sovereign governments a modest 0.13 million (1%).
Quantum Pressure: Why Markets are Pricing in a “Q-Day” Discount
This distribution, visualized in a recent chart from analytics firm Bull Theory, highlights a key vulnerability: the dormant supply. Since Q4 2025, Bitcoin has lagged behind major asset classes, dumping relentlessly despite robust institutional inflows. The culprit? A brewing narrative around quantum computing and the potential reactivation of early-era coins.
Roughly 3.5-4 million BTC from Bitcoin’s nascent days are presumed lost—wallets forgotten, keys misplaced, or owners deceased. This represents nearly 18% of the 21 million cap, a scarcity premium baked into BTC’s value. However, advancements in quantum computing have reignited debates. Quantum machines could theoretically crack older wallets with exposed public keys, allowing these “zombie” coins to flood the market. Even the mere possibility alters supply expectations, as markets preemptively price in this overhang, exerting downward pressure.
BIP 360 & P2MR: Bitcoin’s Proactive Defense Against Future Hacks
Contrast this with institutional adoption. Since 2020, entities like ETFs, funds, and corporates have scooped up 2.5-3 million BTC, rivaling the dormant volume. Yet, this absorption hasn’t buoyed prices as expected. On-chain data reveals 13-14 million BTC redistributed in this cycle—the largest ever—without triggering a meltdown. This resilience suggests the market may overestimate quantum threats.
Importantly, quantum risks aren’t network-wide. Modern wallets use advanced hashing, and Bitcoin’s protocol is adapting. Developers are exploring quantum-resistant cryptography, with proposals like BIP upgrades in discussion. The system isn’t static; it’s hardening.
Ultimately, Bitcoin’s slump reflects a clash of narratives: theoretical supply shocks versus proven adaptability. As global liquidity improves and institutions hold firm, the quantum FUD could dissipate, paving the way for recovery. Investors should monitor on-chain metrics and protocol developments closely—Bitcoin’s strength lies in its evolution, not its ghosts.
