Bitcoin’s Quantum Debate Heats Up As Adam Back Challenges Nic Carter

Blockstream CEO Adam Back publicly criticized Castle Island Ventures partner Nic Carter for his support of Project Eleven, a startup focused on protecting crypto assets from quantum computing threats. Back argued that Bitcoin developers are already researching quantum risks quietly and called Carter’s public warnings "uninformed noise" that causes confusion rather than useful action. He believes the quantum threat is decades away. Carter defended his position, stating he became deeply concerned after discussions with Project Eleven’s CEO and disclosed his financial stake in the project. He warned that governments are preparing for a post-quantum era and called Bitcoin a high-value target if its cryptography remains unchanged. Experts are divided on the timeline. Some, like Capriole Investments founder Charles Edwards, warn the threat could emerge in as little as 2-9 years. Ethereum’s Vitalik Buterin cited models showing a 20% chance of quantum computers breaking modern cryptography before 2030, with a median forecast of 2040. Others, including investor Kevin O’Leary, doubt attacking Bitcoin would be a priority for quantum technology. The debate highlights a split in the crypto community over the urgency of the quantum threat and the value of public warnings.

Bybit Returns To UK’s Crypto Scene Following 2023 Exit — Details

Cryptocurrency exchange Bybit is relaunching its platform in the United Kingdom after halting operations in late 2023 due to stricter Financial Conduct Authority (FCA) regulations. The new UK platform will offer spot trading on 100 digital asset pairs and peer-to-peer (P2P) trading. Bybit's return was made possible through a partnership with Archax, an FCA-approved digital asset exchange, ensuring compliance with anti-money laundering (AML), know-your-customer (KYC), and financial promotion rules. The exchange aims to provide UK users with reliable access to global crypto opportunities within a transparent and compliant framework. This re-entry is strategic, aligning with the UK's growing crypto adoption, though recent FCA data shows a slight decline in ownership from 12% to 8% of adults over the past year.

Crypto market ‘isn’t scared enough’ to call a bottom yet: Santiment

According to Santiment founder Maksim Balashevich, the crypto market has not yet shown sufficient fear on social media to confirm a bottom, suggesting Bitcoin could still drop to around $75,000. He noted that widespread optimism about a near-term reversal contradicts typical bottom formation sentiment. Despite this outlook, the Crypto Fear & Greed Index has been in "Extreme Fear" territory since mid-December. Other analysts offer mixed predictions, with Fidelity’s Jurrien Timmer warning of a potential decline to $65,000 in 2026, while Bitwise’s Matt Hougan remains bullish. Market indicators show conflicting signals, including risk-off positioning among traders.

Canton Network surges on SEC-linked boost – Can CC extend gains?

The Canton Network's native token CC surged 11% in 24 hours, becoming the top daily gainer, following a key regulatory development. The U.S. SEC issued a non-action letter to the Depository Trust & Clearing Corporation (DTCC), clearing the path for tokenized treasury infrastructure on the network. This sparked significant bullish sentiment, with 89% of voters expecting further price gains. The news adds to a series of partnerships that have historically supported CC's price, including a recent integration that previously pushed it up 5%. Market data shows strong bullish positioning. Open interest-weighted funding rates remain positive, indicating long dominance, with $14.28 million flowing into long contracts. Spot markets also saw net inflows of $6.40 million over the past week. However, liquidation heatmaps suggest caution, showing heavier liquidity clusters below the current price, which could lead to a short-term pullback. Despite this, overall sentiment remains constructive due to regulatory clarity, institutional partnerships, and sustained capital inflows.

XRP Analyst Points Out The Best Range To Take Profit

XRP analyst Protechtor identifies a key profit-taking range between $2.50 and $2.68, suggesting a potential 30.9-40.3% upside from the current price of around $1.91. This target aligns with a major resistance zone and prior market reactions. The analysis notes that XRP recently completed a liquidity grab and reacted from the bottom of a running flat Elliott Wave formation, indicating a possible short-term upward move. A stop loss near $1.60 is recommended to manage risk. Despite recent bearish trends, the analyst expects a bounce, citing stretched bearish pressure and a approach toward the 20-month Moving Average, which has historically supported bull cycles.

Analyzing Ethereum’s price rebound as BlackRock shifts $109M in ETH

Ethereum's price rebound to around $2,980 drew significant institutional and whale activity, with large holders like BlackRock moving $108.4M in ETH to Coinbase. This sparked questions over whether it signaled expected downside or profit-taking. Despite the price increase, spot trading volume fell 52%, suggesting weak conviction, while rising Open Interest indicated leveraged positioning was driving stability. Technically, ETH is consolidating in a tight range between $2,790 and $3,000. A break above $3,000 could reverse the downtrend, while a drop below $2,790 may trigger strong selling. Indicators like the ADX and CMF support a bearish near-term outlook, pointing to underlying caution despite the rebound.

Crypto Advocate Senator Lummis Set To Leave Capitol Hill In 2026 – Details

US Senator Cynthia Lummis (R-Wyoming), a leading cryptocurrency advocate, announced on December 19, 2025, that she will not seek reelection in 2026 and will leave the Senate in early 2027.

Her open seat in Wyoming is expected to remain with the GOP.

Bitcoin's apparent demand shrinks, signals new bear market: Analysts

Analysts from CryptoQuant report that Bitcoin's demand growth has significantly slowed since October 2025, indicating a new bear market cycle. Three waves of demand drove the current cycle: the first following the U.S. Bitcoin ETF launch in January 2024, the second after the 2024 U.S. presidential election, and the third from a BTC treasury company bubble. However, institutional demand has contracted, with ETFs shedding around 24,000 BTC in Q4 2025. Funding rates have also dropped to their lowest since December 2023. Furthermore, Bitcoin's price has broken below its critical 365-day moving average support level. While some analysts remain optimistic for 2026 due to potential rate cuts, current sentiment is in "fear" territory, with low expectations for a Fed rate cut in January.
