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 â 31.2% of issued supply. đ
đ Hereâs what matters:
đč 4.33M BTC: Exposure linked to address reuse.
đč 6.26M BTC: Total estimated supply with visible public keys.
đč 1.94M BTC: Additional exposure from certain address types that reveal keys by design.
đč 1.79M BTC: Bitcoin held by exchanges within the exposed-key category, according to the reported analysis.
â ïž 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.
đ What should Bitcoin holders take away?
â Avoid reusing Bitcoin addresses when your wallet supports generating new ones.
â Keep wallet software updated and protect your seed phrase and private keys.
â Remember that a fresh address alone is not a complete quantum-proof solution.
â Watch for credible post-quantum security proposals and practical migration plans from Bitcoin developers.
đ 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 â will quantum-resistant upgrades become one of Bitcoinâs biggest challenges over the next decade? đ
