Citi: Bitcoin may face higher quantum-computing risk than Ethereum, report says
On May 19, 2026, Citigroup researchers said Bitcoin could face greater long-term quantum-computing risk than Ethereum, citing slower governance and the difficulty of implementing major protocol changes. The report noted estimates that practical threats could emerge between 2030 and 2032 and highlighted exposure of public keys during transaction broadcasting. Citi also flagged 6.7 million to 7 million BTC in older wallets with already-exposed public keys, including about one million BTC widely believed to be tied to Satoshi Nakamoto, valued at more than $80 billion.

Bitcoin hit by nearly $650M ETF outflows as macro fears rise, capitulation debated
Bitcoin is facing renewed downside pressure as short-term holder indicators weaken and U.S.-Iran strike concerns lift oil toward $110 per barrel. ETFs opened the week with nearly $650 million in net outflows after $1 billion+ redemptions last week, with ARKB and IBIT each seeing about $310–$324 million leave. Despite heavier selling, sentiment gauges have rebounded from fear to neutral, keeping the capitulation case unresolved.

Short-term holders sell ~15,000 BTC at a loss as support risks breaking below $74,937
Bitcoin fell 5.15% from $81k to $76.9k since Friday, 15 May, with data pointing to heavy short-term holder capitulation. Metrics cited include roughly 15,000 BTC sold at a loss versus 112 BTC of profit-taking over the prior 24 hours, while a break below $74,937 could turn the 4-hour structure bearish. Analysts say a move above $78.2k, steadier spot ETF inflows, and stronger derivatives activity would be needed to improve the setup.

XWIN Research Japan flags 2026 Bitcoin structure risks as BTC breaks $80,000
Bitcoin has fallen below $80,000, pressuring the rebound that had formed from the April lows and putting the market’s resilience under renewed scrutiny. XWIN Research Japan argues the weakness reflects a broader 2026 structure, citing negative Coinbase Premium readings, rising leverage activity, and reduced stablecoin “dry powder” on exchanges. BTC is trading near $76,900 after rejection from the $81,000–$82,000 zone, with focus shifting to the $72,000–$74,000 demand area.
