20% of BTC Quantum-Exposed by Bad Habits, Not Code: Exchanges at Risk

Your Bitcoin is more vulnerable than you think. 4.12 million BTC are exposed to quantum threats not by design, but by user error and exchange negligence. This is a ticking time bomb for P2P volume.

4.12 MILLION BITCOIN ARE EXPOSED TO QUANTUM THREATS.

This isn't a protocol flaw; it's a user behavior crisis. Over 20% of BTC supply is vulnerable due to simple address reuse and partial spending, not outdated code.

4.12 million BTC are at risk, more than double the amount exposed by older script types. This operational risk, driven by how holders manage their keys, dwarfs the structural risk from protocol design.

For Binance P2P and Bybit P2P merchants, this means a significant portion of the liquidity you trade could be compromised. Exchanges, holding 1.66 million BTC, are the biggest culprits, with Binance showing an alarming 85% exposure.

Expect increased volatility and potential P2P volume disruptions as this risk becomes more widely understood. Smart traders will position for the fallout.
