Dogecoin Is No Longer Bearish: Why Analysts Are Predicting A Better Future

With the recent turn in the tide led by Bitcoin crossing $70,000, the Dogecoin price has begun to see some upside . This has been propelled forward by the fact that the meme coin seems to have been stuck in a prolonged accumulation trend, now culminating in an uptrend. As the Dogecoin price continues to chase more rallies, a crypto analyst has called an end to the bearishness that has plagued the digital asset, suggesting that it is time for a change. Dogecoin Is Turning Bullish Crypto analyst Master Ananda published a callout for Dogecoin that suggests that the price may be getting into another bullish trend. In the post made on the TradingView website, the crypto analyst explains that Dogecoin is actually no longer bearish. This comes after the meme coin completed its largest green candle in more than one month, erasing the bearishness that has dominated over the last year. Explaining why Dogecoin is no longer bearish, the crypto analyst points out that rising volumes, as well as the increase in prices, are culminating in the start of another bullish phase. DOGE, on its part, has seen a bullish breakout with momentum during this time. Other factors that the crypto analyst calls out are the green candle and rising volume, followed by strong oscillators and marketwise action, which are pushing the bearish trend. Not only Dogecoin, though, the analyst predicts that the world will begin to lean toward the crypto market , and this is expected to trigger a bullish breakout. Breaking Above $0.1 Holds The Key Another crypto analyst, Crypto Surf, called out a possible continuation of the Dogecoin uptrend, using technical indicators for this. The first of these is the fact that the Dogecoin price had made a clean bounce off the 0.786 Fibonacci level, as well as breaking the long-term confluence at $0.08. This move has effectively broken the RSI downtrend , putting it on a path for further recoveries. For now, the next major level lies at $0.1, and this is where the decision could be made for the meme coin. If it breaks above cleaning and completes a close above this level, then the crypto analyst believes this could be a trigger, and that patience is the key.

Bitcoin’s Quantum Computing Threat: Why Experts Say the ‘Q-Day’ Panic is Premature

BitcoinWorld Bitcoin’s Quantum Computing Threat: Why Experts Say the ‘Q-Day’ Panic is Premature NEW YORK, March 2025 – The cryptocurrency community has buzzed for years about quantum computing’s potential to crack Bitcoin’s encryption, but new analysis suggests these fears may be dramatically overstated. According to Alex Thorn, head of research at Galaxy Digital, while quantum threats represent real technological challenges, market concerns have escalated beyond reasonable levels. This assessment comes as developers worldwide accelerate work on post-quantum solutions, potentially making Bitcoin more resilient than many investors realize. Understanding Bitcoin’s Quantum Computing Threat Quantum computing represents a fundamental shift in computational power. Traditional computers use bits that exist as either 0 or 1. Quantum computers use qubits that can exist as 0, 1, or both simultaneously through superposition. This capability allows quantum machines to solve certain mathematical problems exponentially faster than classical computers. Specifically, they threaten the elliptic curve cryptography that secures Bitcoin wallets. When users create Bitcoin transactions, they generate digital signatures using private keys. These signatures prove ownership without revealing the private key itself. However, quantum computers could potentially reverse-engineer private keys from public addresses using Shor’s algorithm. This theoretical vulnerability has fueled what Thorn describes as “excessive market anxiety” about Bitcoin’s long-term security. The Current State of Quantum Computing Research Significant progress in quantum computing has occurred in recent years. Major technology companies and research institutions continue to achieve milestones in qubit stability and error correction. Despite these advances, practical quantum computers capable of breaking Bitcoin’s encryption remain years, if not decades, away from realization. Several factors limit immediate quantum threats to cryptocurrency: Qubit Stability: Current quantum systems struggle with coherence time Error Rates: Quantum error correction remains a significant challenge Scale Requirements: Breaking 256-bit encryption requires millions of stable qubits Specialized Hardware: Quantum computers need specific environmental conditions Thorn emphasizes that entities capable of triggering “Q-Day” – the moment current encryption becomes vulnerable – currently number only a handful of specialized research groups. These organizations operate under strict regulations and oversight frameworks that would likely prevent malicious use against financial systems. Developer Response and Post-Quantum Solutions The Bitcoin development community has not remained passive regarding quantum threats. Multiple research teams actively work on quantum-resistant solutions that could be implemented through network upgrades. These approaches generally fall into three categories: Solution Type Description Development Stage Post-Quantum Addresses New address formats using quantum-resistant algorithms Research & Testing Hybrid Schemes Combining classical and quantum-resistant cryptography Early Implementation Signature Aggregation Reducing quantum attack surface through optimization Conceptual Design These countermeasures demonstrate Bitcoin’s adaptive capacity through its open development model. The network has successfully implemented major upgrades before, including SegWit and Taproot, suggesting quantum-resistant transitions could follow similar coordinated processes. Historical Context of Cryptographic Transitions Cryptographic systems have evolved continuously since the advent of digital computing. The history of encryption reveals several successful transitions that maintained security while upgrading underlying technology: In the 1990s, the cybersecurity community faced similar concerns about improving computational power breaking existing encryption. The response involved developing stronger algorithms and implementing gradual migration paths. This historical precedent suggests Bitcoin could manage quantum transitions through careful planning and community coordination. Financial institutions and governments worldwide have already begun preparing for post-quantum cryptography. The National Institute of Standards and Technology (NIST) has standardized several quantum-resistant algorithms. These standards provide proven cryptographic foundations that Bitcoin developers could adapt for blockchain applications. Market Implications and Investment Considerations Thorn’s analysis carries significant implications for cryptocurrency investors and institutions. The perception of quantum threats has occasionally created market volatility, with some investors avoiding Bitcoin due to long-term security concerns. However, understanding the realistic timeline and existing mitigation strategies could influence investment decisions. Several factors suggest quantum computing represents a manageable risk rather than an existential threat: Advance Warning: Quantum breakthroughs would be publicly documented Migration Period: Existing coins could move to quantum-resistant addresses Network Effects: Bitcoin’s value incentivizes security preservation Global Coordination: Multiple stakeholders would collaborate on solutions The cryptocurrency industry’s response to previous challenges, including scalability issues and regulatory developments, demonstrates its capacity for adaptation. This track record supports Thorn’s assessment that quantum computing represents a “solvable technological challenge” rather than an immediate crisis. Comparative Analysis with Traditional Finance Traditional financial systems face identical quantum computing threats. Banking infrastructure, stock exchanges, and government financial systems all rely on similar cryptographic foundations. The difference lies in Bitcoin’s transparent development process versus the opaque security upgrades in traditional finance. This transparency allows researchers to publicly analyze Bitcoin’s quantum vulnerability and propose solutions. Traditional systems typically upgrade security through private vendor relationships with limited public scrutiny. Bitcoin’s approach may actually provide advantages in addressing quantum threats through collaborative problem-solving. Furthermore, Bitcoin’s incentive structure creates powerful alignment between developers, miners, and users regarding security preservation. This alignment contrasts with traditional systems where security investments compete with profit motives. The cryptocurrency’s economic model may facilitate smoother quantum transitions than conventional financial infrastructure. Conclusion Bitcoin’s quantum computing threat represents a serious technological challenge requiring ongoing attention and development. However, current market concerns appear disproportionate to the actual risk profile. The combination of quantum computing’s immaturity, existing mitigation strategies, and Bitcoin’s adaptive capacity suggests the network can manage this transition successfully. As Alex Thorn’s analysis indicates, quantum vulnerability represents a long-term consideration for cryptocurrency investors rather than an immediate threat to Bitcoin’s existence. The continued development of post-quantum solutions through Bitcoin’s open development model provides reasonable assurance about the network’s future security. FAQs Q1: What exactly is the quantum computing threat to Bitcoin? Quantum computers could potentially break the elliptic curve cryptography securing Bitcoin wallets by deriving private keys from public addresses using algorithms like Shor’s algorithm, though this requires technology far beyond current capabilities. Q2: How soon could quantum computers break Bitcoin’s encryption? Most experts estimate practical quantum computers capable of breaking 256-bit encryption remain 10-30 years away, with significant engineering hurdles still to overcome in qubit stability and error correction. Q3: What are developers doing to address quantum threats? Research teams are developing post-quantum cryptographic solutions including quantum-resistant address formats, hybrid schemes combining classical and quantum-resistant algorithms, and signature aggregation techniques. Q4: Would a quantum breakthrough immediately endanger all Bitcoin? No, there would likely be an advance warning period during which users could move funds to quantum-resistant addresses, and the Bitcoin network could implement protective upgrades through its consensus mechanism. Q5: How does Bitcoin’s quantum threat compare to traditional banking systems? Traditional financial systems face identical quantum vulnerabilities since they use similar cryptographic foundations, but Bitcoin’s transparent development process may provide advantages in coordinating security upgrades.

Polymarket traders bet on Bitcoin dip below $45,000 by the end of 2026

Bitcoin is experiencing a divided market, as traders on Polymarket indicate it might be below $45,000 at the end of December 31, 2026, with a 51% probability. There is a reasonably balanced market, though YES shares are selling at 51 cents and NO shares at 49 cents. Although sentiment has already ranged between 44% and 49% in previous sessions, the recent shift to the middle suggests a slight shift in expectations, but not a trend. BREAKING: Bitcoin is now projected to crash below $45,000 by the end of this year. 51% chance. pic.twitter.com/dhRug5pM52 — Polymarket (@Polymarket) March 18, 2026 At the same time, the recent decline in Bitcoin provides context for the shift. The asset declined 4.2% to about $70,817, from a level higher than $74,000 in the previous session. Market capitalization fell 4.51% to about $1.41 trillion, while trading volume rose 18.8% to $46.77 billion. Bitcoin timeline for potential cycle bottom Alongside prediction market data, independent analysis indicates a potential cycle low forming later in 2026. Crypto analyst NoLimit highlights historical patterns based on the time between peaks and troughs in cycles. According to the data, Bitcoin bottomed 406 days after the 2012 cycle peak, 363 days after the 2016 cycle peak, and 376 days after the 2020 cycle peak. Based on that framework, the current cycle after the 2024 halving has not yet hit the projected bottom window. Consequently, the analysis indicates that a major low could appear between October and November 2026. NoLimit noted, “I wouldn’t be surprised to see bitcoin between $45k and $50k by the end of 2026.” The projection matches a possible price range of $45,000 – $50,000, supporting the bearish scenario in Polymarket pricing. In addition, Net Unrealized Profit and Loss (NUPL) is cited by NoLimit as a key indicator on-chain. Historically, Bitcoin has gone into a “blue zone” on this metric around major bottoms, such as the 2018 bear market, the 2020 crash caused by the Covid-19 pandemic, and the 2022 crash. However, as of now, Bitcoin has not yet reached that level in the current cycle. Whale selling intensifies short-term volatility Recent activity on-chain is also contributing to market uncertainty. Blockchain analytics platform Lookonchain reported that a long-dormant Bitcoin wallet sold 1,000 BTC, valued at around $71 million. The same entity has offloaded 3,500 BTC since November 2024 at an average price above $96,000, resulting in an estimated profit of $442 million, or a 266x return. Additionally, another early holder linked to Owen Gunden sold 650 BTC after earlier disposing of 11,000 BTC worth over $1.1 billion. At the macro level, external factors also put pressure on sentiment. Bitcoin OG Owen Gunden, who previously sold 11K $BTC ($1.12B), sold another 650 $BTC ($46.3M) 10 hours ago. https://t.co/Fx6wtq0Whm https://t.co/dU3RoJViyh pic.twitter.com/K6e9RwwWsD — Lookonchain (@lookonchain) March 19, 2026 A recent hawkish Fed rate announcement on Wednesday, when the central bank did not change the benchmark interest rate but only indicated a slower rate of decrease going forward, left risk-asset bulls dissatisfied. The hawkishness was reflected in the so-called interest-rate “dot plot,” which indicates how the Fed’s voting members anticipate interest rates in the coming months. The median projection showed that this year will see only one rate cut, despite recent labor-market weakness. The smartest crypto minds already read our newsletter. Want in? Join them .
