Europol says Bitcoin blockchain resists quantum attacks, but 30% of coins in exposed wallets risk theft.

Europol's European Cybercrime Centre reports that Bitcoin's blockchain remains secure against quantum computing attacks due to its hash functions. However, about 30% of Bitcoin, roughly 6 to 6.9 million BTC, is held in wallets with exposed public keys, making them vulnerable to theft if quantum computers become powerful enough. The agency advises moving these funds to safer wallets and adopting post-quantum cryptography to protect assets. The challenge lies in coordinating this migration, as Bitcoin lacks a central authority to enforce updates, and the process could take over 76 days of cumulative processing time.

The Europol report on quantum computing and Bitcoin security provides context for digital asset markets. For readers following cryptocurrency trends, here is Pluang's market snapshot as of Oct 08, 2026 10:32 WIB: out of 50 major cryptocurrencies, 18 rose and 31 fell. Notable moves include SXP down 46.27% at Rp37, BAL up 11.14% at Rp16.297, and CRV up 9.57% at Rp7.053 with a Pluang order activity of 52% Sell and 48% Buy.
