Fidelity's Jurrien Timmer points to a possible Bitcoin floor around $65,000 in 2026, while BTC trades near $88,100 and key EMAs signal short‑term pressure. Metaplanet's ADRs begin US trading on December 19, 2025 with Deutsche Bank Trust Company Americas as depositary, and MSCI's index exclusion proposal for firms holding over 50% digital assets could be decided by January 15.

Bitcoin is trading sideways as $415 million in options are scheduled to expire over the next seven days, with half of that open interest due on 26 December. If buyers can continue to defend the $85k–$88k support band through the expiry window, analysts expect conditions for a FOMO-driven breakout and a bullish base heading into 2026.

Blockstream CEO Adam Back criticized Nic Carter on X on Friday for amplifying quantum risk narratives around Bitcoin. Carter said Castle Island Ventures invested in Project Eleven and disclosed the stake on October 20. The debate deepened after Charles Edwards warned that quantum computers could threaten Bitcoin within 2–9 years if security is not upgraded.

On 20 December 2025, BlackRock's spot Bitcoin ETF IBIT ranked among the year's leading ETFs by inflows, even though it has posted negative returns in 2025. The fund attracted more than $25 billion in new capital, indicating investors are prioritizing long-term Bitcoin exposure over short-term price performance and increasingly viewing Bitcoin ETFs as structural portfolio assets comparable to gold.

Cynthia Lummis, the junior U.S. senator from Wyoming since 2021, announced on December 19, 2025 that she will not seek another term, citing the demands of six more years. A longtime bitcoin advocate, she reportedly first bought BTC in 2013, and filings from 2021 show purchases between $50,000 and $100,000. She has championed pro‑crypto legislation, including calls for a strategic U.S. Bitcoin reserve.

Bitcoin has slipped about 3% for the week to $88,000 after briefly rebounding from $84,500, with on-chain data highlighting that zone as the strongest current support. Analyst Ali Martinez notes that a break below roughly $83,300 could open the way to deeper supports at $79,520, $70,685, and $63,111. The price also faces heavy sell walls just above the market, including resistance around $90,000, $92,000 and a major barrier near $94,000.

On Friday, her office said Sen. Cynthia Lummis will retire when her term concludes in early 2027. During her tenure, she advanced crypto frameworks and introduced an AI liability bill tied to disclosure requirements. According to NBC News, two sources said Rep. Harriet Hageman is likely to run for the deep-red Wyoming seat.

On December 19, 2025, Blockstream CEO Adam Back publicly challenged Nic Carter's warnings that quantum computing poses an imminent threat to Bitcoin. Back said developers are quietly preparing, while Carter cited Castle Island Ventures' investment in Project Eleven and an Oct. 20 Substack disclosure to argue the risk is real and underappreciated.
