Adam Back says Bitcoin must prepare quantum-resistant shift; Satoshi holdings could be estimated
Bitcoin could reveal how much bitcoin Satoshi Nakamoto can actually access if it shifts to a post-quantum system, a claim has emerged. Blockstream CEO Adam Back (아담 백) said the safest approach is to design an optional upgrade that allows a move to quantum-resistant cryptography if needed. That shift could help gauge the effective size of Satoshi-linked holdings. Separately, a proposal to restrict movement of quantum-vulnerable coins has drawn criticism as confiscatory.

Gemini Winklevoss calls \'extreme fear\' an opportunity as bitcoin selling surges
U.S. crypto exchange Gemini has delivered an optimistic message despite a market slump, but is also selling bitcoin and pushing through major restructuring, the report said. On-chain data showed bitcoin holdings in a Winklevoss Capital wallet fell from about 23,000 BTC in February 2025 to under 11,000 BTC in February 2026. Gemini is exiting several markets, planning staff cuts and reshaping leadership as costs rise and market share shrinks.

Arthur Hayes says bitcoin could hit record high in 2026 if dollar liquidity expands
BitMEX co-founder Arthur Hayes says bitcoin’s poor showing in 2025 was driven by a contraction in U.S. dollar liquidity rather than any structural problem. In an essay, he contrasts bitcoin’s decline with gold’s rise and the Nasdaq 100’s resilience. Hayes says risk assets including bitcoin could rebound if dollar liquidity expands from 2026. He cites three drivers: Fed balance-sheet growth, expanded strategic-industry bank lending and MBS purchases ordered for Fannie Mae and Freddie Mac. He also outlined his investment positions.
