Satoshi-Era Bitcoin (BTC) Whale's $8B Move Explained Amid Looming Quantum Computing Threat to Crypto

According to @AltcoinGordon, a recent $8 billion Bitcoin (BTC) transfer by a Satoshi-era whale is likely a wallet security upgrade rather than a market sale, as suggested by on-chain analytics firm Arkham. The funds were moved from legacy addresses to more secure and efficient native SegWit bc1q-style addresses, and Arkham reports the BTC remains untouched. Ledger CTO Charles Guillemet noted that legal notices sent via OP_RETURN messages to the old wallets may have prompted the owner to move the funds as a precautionary measure. This event highlights the growing importance of wallet security, which is further underscored by the imminent threat of quantum computing, or 'Q-Day'. Experts like IBM Quantum's Jay Gambetta warn that 'Harvest Now, Decrypt Later' attacks are already underway. The crypto market faces significant risk, with researchers estimating 4 million BTC are vulnerable, and BlackRock has officially listed quantum computing as a risk in its Bitcoin ETF filing. Ethereum co-founder Vitalik Buterin has already proposed emergency hard-forks to address this cryptographic threat, but researchers at the University of Kent warn such an upgrade could lead to 75 days of downtime for the Bitcoin network, posing a major risk to the asset class.

Vitalik Buterin Warns Ethereum (ETH) Is At Risk: 3 Key Tests for Crypto Project Decentralization

According to @VitalikButerin, the Ethereum co-founder stated that the crypto industry is at an “inflection point” and that decentralization must become a concrete user guarantee rather than just a catchphrase. Speaking at the Ethereum Community Conference, Buterin warned that too many Layer-2 networks, DeFi projects, and “decentralized” front-ends rely on insecure elements like hidden backdoors and instant upgrade buttons, which can be hacked. He outlined three practical tests for every crypto project's security: the “walk-away test” (do users keep assets if the company disappears?), the “insider attack test” (how much damage can rogue insiders cause?), and the “trusted computing base” test (how much code must be trusted?). Buterin stressed that if Ethereum (ETH) fails to build systems that pass these tests, it risks becoming obsolete and losing its competitive edge.
