More Than 6 Million BTC Have Exposed Public Keys
More than 6 million BTC, or 31.2% of Bitcoin’s circulating supply, sit behind public keys visible on-chain, according to Glassnode data. That is about 5 to 6 percentage points above the 2023 low. Glassnode co-founder Rafael Schultze-Kraft said exposed Bitcoin supply has risen by 222,000 BTC since May, while exchanges account for 123,000 BTC of that increase. Exchanges now hold 1.79 million BTC with visible public keys. Exposure varies by platform, from 10% at Coinbase to 83% at Binance. Public-key visibility can result from address reuse or certain Bitcoin output types. It does not mean those coins are currently vulnerable: no practical attack on Bitcoin or ether wallet keys has been demonstrated. The figures have renewed attention on long-term cryptographic risks, following Ethereum researcher Justin Drake’s warning that the industry should prepare for a worst-case AI-driven attack scenario.
Neutral
The data highlights a long-term security concern, but it does not point to an immediate vulnerability or a confirmed attack. The article says no practical attack on Bitcoin or ether wallet keys has been demonstrated, and public-key visibility is a measure of address and output exposure—not proof that funds can be stolen. For trading, the figures may prompt short-term discussion about wallet security and increased volatility if traders interpret AI or quantum-computing warnings as imminent threats. However, the article provides no direct evidence of a current exploit, market-wide losses or a change in network operations, so a sustained price impact is uncertain. Similar past security warnings have often triggered brief risk-off reactions, while prices ultimately depended more on concrete exploit evidence and broader market conditions. Longer term, the figures could strengthen calls for address-use changes and cryptographic upgrades. Until a credible attack method or clear migration plan emerges, the likely market effect is limited and sentiment-driven rather than fundamentally bearish or bullish.
