Ethereum co-founder Vitalik Buterin has sold 3,788.57 ETH, worth about $7.3 million, over a 72-hour span. The sales, part of a broader \u0022mild austerity\u0022 phase, come as the crypto market corrects and have sparked debate over their impact on ETH\u0027s bearish price action.

Venture capitalist Vinny Lingham warned on Monday that Bitcoin's hold above $60,000 could decide the fate of the current cycle. With BTC down 4.4% at $64,498, he flagged $64,000 as an immediate danger zone and $60,000 as the key support. He said a break below $60k could trigger violent liquidations and corporate treasury stress.

During a recent podcast, MicroStrategy founder Michael Saylor said there is currently no consensus in the Bitcoin network on the so-called quantum computing threat, describing it as another alarmist narrative. He compared these concerns to past fears such as China's role in mining and argued that most such narratives function as business models for those promoting them. Saylor added that potential upgrades to address quantum issues should be approached over roughly a 10-year horizon as global consensus emerges.

Ethereum co-founder Vitalik Buterin has outlined a new framework for thinking about blockchain security, arguing that the divide between security and user experience is largely artificial. He emphasizes minimizing the gap between what users intend and how systems actually behave, calling for redundancy-based protections in Ethereum wallets and dApps. Buterin also suggests using large language models as an additional, but not exclusive, layer to help interpret and verify user intent.

Bitcoin fell more than 5% below $65,000 in early Asia trading on Monday, as fresh tariff headlines stirred nerves. CoinGecko data shows about $464 million was liquidated in the past 24 hours; traders warn a daily close above $71,000 is needed, with bears watching $42,000–$45,000.

Bitcoin has fallen 29% over the last 30 days, with VanEck's latest Bitcoin ChainCheck report arguing that leveraged positions have been cleared and "mid-cycle" sellers are largely spent. The asset manager also notes a sharp pullback in hash rate and mining profitability, while on-chain activity and transaction counts remain comparatively strong.

Vitalik Buterin pushed back against an X user's suggestion to abandon Ethereum's base chain, outlining a tightly integrated "bolt-on" rebuild that keeps the network live. He described a cypherpunk-focused redesign that grows alongside the current chain, and said a roughly five-year timeline could be shortened with AI-assisted coding and verification.
