According to Glassnode data reported on October 8, around 4.33 million $BTC sit in reused addresses, while total public-key exposure reaches approximately 6.26 million BTC — 31.2% of issued supply. 👀
📊 Here’s what matters:
🔹 4.33M BTC: Exposure linked to address reuse.
🔹 6.26M BTC: Total estimated supply with visible public keys.
🔹 1.94M BTC: Additional exposure from certain address types that reveal keys by design.
🔹 1.79M BTC: Bitcoin held by exchanges within the exposed-key category, according to the reported analysis.
⚠️ Does this mean Bitcoin is hacked? NO.
Visible public keys do not mean private keys have been stolen. The concern is a future quantum computer powerful enough to break the cryptography Bitcoin uses to authorize transactions. No such attack has been demonstrated at this scale.
🔐 What should Bitcoin holders take away?
✅ Avoid reusing Bitcoin addresses when your wallet supports generating new ones.
✅ Keep wallet software updated and protect your seed phrase and private keys.
✅ Remember that a fresh address alone is not a complete quantum-proof solution.
✅ Watch for credible post-quantum security proposals and practical migration plans from Bitcoin developers.
📈 My take: This is a long-term security challenge, not a reason to panic-sell $BTC today. The real test will be whether Bitcoin can coordinate a safe transition before quantum computing becomes a practical threat.
What do you think — will quantum-resistant upgrades become one of Bitcoin’s biggest challenges over the next decade? 👇
