Bitcoin’s Security Model May Shift As Quantum Computing Moves Forward: Analyst

Coinbase research lead David Duong warns that quantum computing advancements could threaten Bitcoin's security and economic model. Two primary risks exist: quantum computers could break cryptographic signatures to steal funds from addresses with exposed public keys (about 33% of Bitcoin's supply), and they could dominate mining by solving proofs of work much faster. While current quantum machines are not yet capable, experts are preparing for "Q-day" by developing quantum-resistant cryptography and promoting best practices like avoiding address reuse. The transition would require broad consensus and remains a complex, long-term challenge rather than an immediate threat.

Bitcoin Core V30 Bug Risks Total Wallet Loss For Legacy Users

Bitcoin Core developers issued an urgent warning regarding a critical bug in versions 30.0 and 30.1 that, in rare cases, can delete all wallet files on a node during legacy (BDB) wallet migration, potentially leading to fund loss for users without backups. A fix is expected in version 30.2, and users are advised to avoid migrating legacy wallets until then. The disclosure sparked debate within the community, with some arguing the risk is understated since v30 forces migration for legacy wallet users, while others noted limited real-world impact with only one user reportedly affected. All agree on the precaution: back up wallets and delay migration until the patch is released.

Bitcoin Value Days Destroyed Reaches Lowest Point Of The Current Cycle, A Structural Calm?

Bitcoin's price is retesting the $94,000 level, yet on-chain metrics indicate a divergence. The Bitcoin Value Days Destroyed (VDD) ratio has dropped to a cycle low of 0.55, signaling a significant decline in selling pressure from long-term holders. This suggests reduced coin movement and a structural calm, as long-term investors are holding at current prices. Despite recent volatility, BTC remains within a multi-year ascending channel, forming higher lows and maintaining its upward trend as long as it stays above key support levels.

Clearing the Decks

In early January 2026, Bitcoin broke out from a prolonged consolidation near $87k, rising 8.5% to $94.4k, as profit-taking pressure declined significantly. The market now faces overhead supply between $92.1k and $117.4k from recent buyers, creating resistance. A key recovery signal would be a sustained move above the Short-Term Holder Cost Basis of $99.1k. If not, bearish risks may increase. ETF flows are turning positive, futures open interest is rebuilding, and options markets show renewed upside interest with volatility bottoming and skew normalizing. Dealer gamma has flipped short, suggesting less dampening on upward moves. The market has cleared significant legacy positioning, entering 2026 with improved structure and renewed potential for expansion.

Bitcoin prices rise: Are BTC ETF inflows setting up a $100K move?

Bitcoin has started the week bullishly, breaking and holding above $90,000, signaling stronger demand and improved stability. The Short-Term Holder Net Unrealized Profit/Loss (STH NUPL) is approaching zero, indicating that most short-term holders are near breakeven around $93,450. A decisive break above the $99,000 breakeven level could confirm a bullish continuation toward $100,000. Institutional and retail investors are returning to accumulation. U.S. spot Bitcoin ETFs saw significant net inflows of $452.4 million over two days, reversing previous sell-offs. Additionally, over $480 million worth of BTC was withdrawn from exchanges into private wallets, reducing available sell pressure. Globally, rising M2 money supply supports risk assets like Bitcoin, though the impact may take months to materialize. Improved short-term holder sentiment, renewed institutional interest, and favorable macro conditions strengthen the case for further upside in the near to medium term.

Bitcoin Hitting All-Time High Every Year Has ‘Good Odds,’ Says Galaxy Executive, Claims All Institutions Should Buy

A senior Galaxy Digital executive expressed strong optimism about Bitcoin's long-term prospects, stating there are "good odds" it reaches a new all-time high every year despite ongoing volatility. Zac Prince, head of Galaxy One, views Bitcoin as a long-term portfolio asset combining store-of-value characteristics with venture-style upside, driven by structural tailwinds like institutional adoption via ETFs. He believes all institutions should have a Bitcoin allocation, citing its positive impact on portfolios. Prince also discussed Galaxy's new cash yield product offering up to 8% annual yield for accredited investors, backed by the company's balance sheet. Meanwhile, Bitcoin recently broke above $91,483 resistance but remains nearly 30% below its October 2025 all-time high of $126,198, currently trading around $91,905.

Bitcoin Mining Turns Green as Waste Heat Powers Canadian Agriculture

Canaan, a Bitcoin mining hardware manufacturer, has launched a 3MW green energy project in Manitoba, Canada, to repurpose waste heat from mining operations for agricultural use. The project uses liquid-cooled mining rigs and a closed-loop heat exchange system to capture heat, producing hot water above 75°C to warm tomato greenhouses in cold climates. This initiative reduces heating costs, cuts fossil fuel reliance, and lowers carbon emissions. Approximately 90% of the electricity used is recovered as usable heat at a low cost of $0.035 per kWh. The project demonstrates Bitcoin mining’s potential to support real-world industries sustainably and may be replicated in other cold regions.

Bitcoin Investor Behavior Diverges: Whales Buying, Retail Selling

Recent on-chain data from Santiment reveals a divergence in Bitcoin investor behavior. While retail investors (holding less than 0.01 BTC) have been selling, sharks and whales (holding 10 to 10,000 BTC) have been accumulating since December 17th, adding 56,227 BTC ($5.2 billion). This whale accumulation marked a local market bottom. Initially, both groups bought during consolidation, but after Bitcoin's recent price breakout, retail began selling, possibly viewing the rally as a bull trap. Santiment considers this setup "very bullish," as whale buying combined with retail selling historically suggests a higher probability of continued market growth. Bitcoin is currently trading around $92,600, up over 5% in the past week.

Bitcoin ETFs’ ‘lion-like’ performance could see $150B in annual inflows

Bitcoin ETFs saw significant institutional inflows of $1.2 billion in the first two trading days of 2026, described by analysts as "lion-like" and potentially signaling $150 billion in annual demand. Despite a net outflow of $243 million on January 6, the inflows showed signs of long-term conviction rather than short-term arbitrage, as CME Open Interest remained low. However, broader Bitcoin demand remains negative, hindering a sustained price rally. BTC continues to face resistance around $94K–$96K, a key barrier to reaching $100K. A stronger recovery depends on consistent ETF inflows and a broader shift in market demand.
