The Quantum Computing Threat to Bitcoin

Bitcoin faces an existential threat from quantum computing, which could break the elliptic curve digital signature algorithm (ECDSA) securing the network. Approximately 25% of all bitcoin—including the 1.1 million BTC in Satoshi’s wallet—are stored in vulnerable early "pay-to-public-key" addresses, where public keys are exposed on the ledger. Later address types only reveal public keys during transactions, creating a brief attack window. The timeline for quantum computing is uncertain, but if it emerges before Bitcoin transitions to post-quantum cryptography (PQC), attackers could steal and liquidate billions in bitcoin, causing a market collapse. A coordinated migration to quantum-resistant algorithms is urgently needed, though implementing PQC could take 6 months to 2 years. A controversial proposal suggests "burning" un-migrated coins to prevent mass theft, but this risks setting a precedent for confiscation and contradicts Bitcoin’s core principles of individual sovereignty. As the largest financial "honeypot" with direct and liquid value, Bitcoin is a prime target. The network must proactively upgrade before quantum computers become capable of breaking current encryption.

Bitcoin Supercycle 2026 Cancelled! — Changpeng Zhao (CZ) Explains Why

CZ, the former CEO of Binance, has reversed his previous prediction of a Bitcoin "supercycle" in 2026. He now expresses uncertainty about a major bull run in the near term due to recent market turbulence. Key factors for his changed outlook include widespread FUD (fear, uncertainty, and doubt), misinformation on social media, macroeconomic instability, and geopolitical tensions, all contributing to high volatility and significant liquidations. While he was previously optimistic about institutional adoption and pro-crypto policies, CZ now advises the crypto community to focus on long-term strategies like "buy and hold" rather than reacting to short-term market noise. He remains cautiously optimistic about Bitcoin's long-term potential but stresses that the current global climate makes forecasting unreliable.

The Glamour Belongs to the 'Epsteins', Saylor Just Wants to Hoard Bitcoin

Summary: The recently unsealed Epstein files revealed an unexpected connection to Michael Saylor, CEO of MicroStrategy (now Strategy). In a 2010 email, Epstein's PR coordinator, Peggy Siegal, complained about Saylor's presence at a high-society dinner, describing him as a "zombie on drugs" who was impossible to engage socially and had no personality or understanding of social etiquette. This social awkwardness, however, may have been his saving grace, as it from deeper involvement in the scandal. This perceived personal flaw is presented as a professional strength in his role as a Bitcoin maximalist. Saylor’s company is the largest corporate holder of Bitcoin, with 712,647 BTC purchased at an average cost of $76,037. Despite recent market volatility pushing the price down and his company's stock falling 60%, Saylor remains committed to his strategy of buying Bitcoin weekly, famously tweeting "More Orange" to signal his intent to continue accumulating. The article argues that the traits that made him a social outcast—being闷 (boring), uninteresting, and unresponsive to external noise—are the exact same traits that make him a successful "Bitcoin zombie." His strategy is simple and requires no complex decision-making: buy and never sell. While his approach is not advisable for the average investor without his corporate financial tools, the core lesson is that in investing, "interesting" strategies like frequent trading and chasing hype often lead to losses. The most profitable strategies are often boring. The piece concludes that both in investing and in life, the spotlight of "热闹" (excitement/hot spots) is often fleeting and dangerous, while long-term value is found in committed, "boring" work.

Bitcoin: From $124,700 to $78,000 – BTC’s rise, fall, and reality check

Bitcoin's price has fallen to $78,441 in early 2026, erasing nearly all gains from its 2025 rally that peaked at a record $124,700 in October. The decline drivers include the hawkish Federal Reserve Chair nomination, geopolitical tensions, capital rotation away from risk assets, large liquidations, fading spot Bitcoin ETF interest, and unmet expectations like a U.S. Bitcoin reserve. This has revived fears around Satoshi Nakamoto’s unmoved coins, though some see it as a market-clearing phase. Technically, indicators like MACD remain bearish, but oversold RSI levels suggest potential support and a short-term bounce. Market sentiment strain persists, yet Bitcoin’s high dominance indicates capital isn’t fleeing to altcoins, leaving the market in a tense waiting phase.

Breaking Downward: Where Is Bitcoin's Bottom? How to Operate Now?

Bitcoin has broken down below the key $80,600 support, confirming a weekly C-wave decline as anticipated. The current bearish trend is part of an A-B-C correction structure that began after the $126,200 high in October 2025. Technical analysis suggests further downside potential, with key support levels at $74,500–$75,200 (Fibonacci 50% retracement and April 2025 low), $69,000–$72,500 (Fibonacci 61.8% level), and $64,500–$65,500. However, improved liquidity and positive policy expectations may limit severe declines, potentially leading to a prolonged consolidation. Short-term trading using proprietary momentum and spread models yielded a 5.1% profit last week by shorting the rebound at ~$89,268 and covering near $84,000. Current weekly and daily indicators show strong bearish momentum with no clear bottom signal yet. This week, Bitcoin is expected to trade within a range, with resistance at $80,000–$80,600 and $84,000–$86,500. Support is at $74,500–$75,200. Trading strategies recommend maintaining 60% short exposure for medium-term and using 30% capital for short-term scalping based on model signals. Two scenarios are outlined: shorting rebounds near $80,600 (Scheme A) or breaking below $75,200 (Scheme B), both with strict 1.5% stop-loss and dynamic profit protection rules.

Bitcoin Continues to Plunge, Focus on Whether MSTR Is Forced to Sell

Bitcoin is undergoing a severe stress test as its price falls below key psychological levels, approaching the cost basis of major institutional holders like MicroStrategy. The cryptocurrency dropped below $80,000 over the weekend, hitting its lowest point since April 7, 2025, and has declined over 30% recently amid thin liquidity. Despite the sell-off, MicroStrategy’s Executive Chairman Michael Saylor signaled intentions to continue accumulating Bitcoin, even as the company raised the dividend on its perpetual preferred shares to 11.25% to attract capital. However, analysts warn that high dividend costs could strain cash flow if Bitcoin’s price remains stagnant or falls below its cost basis. The market is highly institutionalized, with MicroStrategy and 11 spot Bitcoin ETFs holding approximately 10% of Bitcoin’s circulating supply. These institutions face combined unrealized losses of around $7 billion, with an average acquisition cost of $85,360 per Bitcoin. Spot Bitcoin ETFs have seen net outflows for 10 consecutive days, exacerbating downward pressure. MicroStrategy holds 712,647 Bitcoin at an average cost of $76,037. With Bitcoin hovering near $78,000, its unrealized gains have narrowed to less than 3%. The company’s aggressive financing strategies, including high-yield debt, highlight both its commitment and the risks of its Bitcoin-centric strategy. Macro strategist Jim Bianco notes that Bitcoin faces a "narrative exhaustion," as the "institutional adoption" story has been fully priced and may now be reversing. Without new sustained buying interest, institutional holdings—once a support—could become a major source of selling pressure. The key question is where the next wave of buyers will emerge at current price levels.

Bitcoin Continues to Plunge, Whether MSTR Is Forced to Sell Becomes Focus

Bitcoin is experiencing a sharp decline, falling below the key $80,000 level and approaching the cost basis of major institutional holders like MicroStrategy. This has intensified concerns about potential forced liquidations among highly leveraged players. Despite the sell-off, MicroStrategy's executive chairman Michael Saylor signaled intentions to continue accumulating Bitcoin, even as the company raised dividends on its preferred shares to attract capital—a move that could strain cash flow if prices fall further. Analysis indicates that institutional entities, including ETFs and MicroStrategy, now hold approximately 10% of Bitcoin’s circulating supply, with an average acquisition cost around $85,360. At current prices, these positions are underwater, with unrealized losses totaling about $7 billion. The market is facing a crisis of narrative, as the once-bullish "institutional adoption" theme has reversed, with ETF outflows persisting and no new catalysts emerging to attract buyers. The high concentration of institutional holdings, largely at a loss, may now become a source of sustained selling pressure.

Bitcoin hits April 2025 levels – $85K bounce for BTC possible IF…

Bitcoin fell to a 9-month low of $75,519, hitting levels last seen in April 2025, before a slight recovery to $78,862. The decline is attributed to a significant drop in capital inflows and persistent selling pressure from both retail and institutional investors. Realized Cap data indicates no fresh capital entering Bitcoin recently, while ETF outflows and increased exchange netflows signal aggressive selling. With over $736 million in long positions liquidated and strong bearish momentum, BTC may continue trading below $80k. Key support lies at $76k, though a potential rebound to $85k–$92k is possible in early February under improved conditions.
