Bitcoin quantum risk: Glassnode dey flag say ~20% of BTC dey exposed
Glassnode study on "Bitcoin quantum risk" talk say 30.2% of issued BTC dey for two exposure categories, and about 20.6% of supply dem mark as operationally vulnerable.
The report split exposure like this:
- Structural exposure (1.92M BTC, 9.6%): public keys dey show directly because of output design, including old P2PK, bare multisig, and the newer Taproot (P2TR).
- Operational exposure (4.12M BTC, 20.6%): coins wey look safe when dem dey rest fit become exposed after dem spend am, because transaction signature go show the public key. If the same address later receive more funds (address reuse), the later balances go inherit the exposure.
Plenty of the operationally unsafe BTC dey tied to exchange balances, Glassnode mention say Binance and Bitfinex get much higher exposed shares compared to Coinbase. Separate notes still claim 0% quantum exposure for holdings for US, UK, and El Salvador.
For traders, this no be immediate "break crypto" catalyst. The main point na potential risk-premium story: "Bitcoin quantum risk" fit increase over time as exposed coins dem spend and reuse, and exchange plus custody practices fit shape sentiment more than protocol design alone.
Neutral
Di study dem frame as one long-term security story, not like one short-term cryptographic break. E point say about 20% of BTC dey operationally vulnerable—especially balances wey dey related to exchanges—but di report logic depend on future quantum capabilities (Shor-style decryption) and on how coins go later get spent and reused. Dat mean market reaction fit more likely be driven by sentiment (risk premium around custody/exchange practices) than be direct, immediate BTC price driver. For short term, traders fit treat am as informational and focus on broader drivers; for long term, e fit small affect perceived risk for custodied/active address clusters without forcing immediate repricing.
