Europol urged the crypto industry and policymakers to prepare for quantum computing risks, warning cryptocurrency wallets using public and private keys are a key exposure point. It said blockchains’ hash functions and mining structures are relatively safer, but wallets with public keys already exposed on-chain could be hard to protect once attacks begin. Europol cited estimates of 6.04 million bitcoin exposed and flagged technical hurdles in switching to quantum-resistant signatures.

This week’s key issue in digital assets was the Clarity bill, which failed to clear a U.S. Senate cloture vote and pushed bitcoin down into the $76,000 range. Unresolved disputes included stablecoin interest payments, whether developers and infrastructure providers fall under money-transmitter rules, and ethics rules tied to President Donald Trump’s crypto business. In South Korea, debate revived over the government’s plan to start taxing digital assets in 2027. Markets also revisited quantum-computing risks and tokenisation investment moves.
