It sounds out of a sci-fi video game, but new research suggest quantum attackers could break Bitcoin’s blockchain and steal coins mid-transaction sooner than it was originally expected. Is Doomsday Near For Bitcoin? A new whitepaper and blogpost published on Tuesday by Google’s Quantum AI team claims that Bitcoin and Ethereum’s cryptography can be broken with fewer than 500,000 physical qubits and roughly 1,200 “logical” qubits, far below the “millions” that used to be cited. Related Reading: Hyperliquid’s Tokyo Edge Exposed — Secret Time Gap Is Tilting The Market Most blockchains and cryptocurrencies protect wallets and transactions using 256‑bit elliptic curve cryptography (a very strong mathematical lock) based on the discrete logarithm problem (ECDLP‑256). The research points at a significant decreased in the resources needed to break the ECDLP-256. The blog post says: We estimate that these circuits can be executed on a superconducting qubit CRQC with fewer than 500,000 physical qubits in a few minutes, given standard assumptions about hardware capabilities that are consistent with some of Google’s flagship quantum processors. This is an approximately 20-fold reduction in the number of physical qubits required to solve ECDLP-256 and a continuation of a long history of gradual optimization in compiling quantum algorithms to fault-tolerant circuits. “Cryptographically-relevant quantum computers (CRQS) pose a threat to widely deployed public-key cryptography”, the whitepaper claims. Instead of attacking wallets, the research models a live attack where a quantum adversary could steal bitcoin mid‑transaction in about 9 minutes by quickly using the briefly revealed public key to calculate the private key, giving a 41% chance of beating Bitcoin’s 10‑minute block time. In this sense, Ethereum might be less vulnerable than Bitcoin, as it confirms its transactions faster. The Culprit: Taproot This results put Taproot, Bitcoin’s 2021 upgrade, in a different perspective. Although Taproot boosted privacy and efficiency, it started exposing public keys on‑chain by default, stripping away the “hash-first” protective layer that older address formats had. Therefore, it has widened the pool of quantum‑exposed coins to about 6.9 million BTC, including Satoshi‑era and heavily reused addresses. A quantum computer is a computer that uses the rules of quantum physics to process information in ways normal computers can’t. Instead of bits that are either 0 or 1, it uses qubits, which can be 0, 1, or a blend of both at the same time, letting the machine explore many possibilities in parallel. Classical computers explore possibilities one‑by‑one (even if very fast). This means that, for certain math problems (like factoring huge numbers used in cryptography), a powerful quantum computer could solve in minutes what would take a classical supercomputer longer than the age of the universe. What This Means For Concerned Traders Despite it is true that no such machine exists yet, earlier this month Google set 2029 as an internal deadline for post‑quantum migration, compressing the perceived timeline for “Q‑day.” Researchers warn that post-quantum migration will take years, even if the hardware is not here yet.

Coin Metric co-founder and Bitcoin advocate Nic Carter highlighted another paper released today from Oratomic, Caltech and UC Berkeley, showing quantum computers can break crypto with just 10,000 reconfigurable atomic qubits. and the craziest thing is that the Google Quantum AI paper (above) is maybe not even the most concerning quantum paper released _today_https://t.co/mSZi5Lk7do — nic carter (@nic_carter) March 31, 2026 Roughly one‑third of Bitcoin’s supply is now modeled as potentially quantum‑exposed over a long enough horizon, which could change how desks value old coins, Taproot usage and address‑reuse hygiene. Traders should watch for Taproot adoption metrics, progress or gridlock around BIP‑360‑style upgrades, and whether Bitcoin devs move toward a dated migration plan as Google’s 2029 clock ticks louder.

XRP may be showing one of the cleaner accumulation signals in an otherwise weak altcoin market, according to CryptoQuant analyst Darkfost, who pointed to a pickup in Binance outflow transactions as the token continues to trade inside a narrow multi-month range. XRP Flashes This Bullish Signal The setup matters because XRP has held between roughly $1.30 and $1.50 for several months even as broader market conditions have remained difficult, particularly for altcoins. In Darkfost’s reading, that sideways stretch is not just stagnation. It may also be a period in which buyers are quietly repositioning. “Despite difficult conditions for the crypto market, and especially for altcoins, some assets are still showing a certain degree of resilience,” Darkfost wrote. “This is particularly the case for XRP, which has been trading in a well-defined range for several months, oscillating between $1.30 and $1.50. While the asset is still trading more than 60% below its last all-time high, some investors appear to be taking advantage of this consolidation phase to gradually accumulate.” Related Reading: XRP Nears Key Turning Point As Descending Wedge Tightens The chart shared via CryptoQuant focuses on Binance exchange outflow transactions, broken down by XRP size bands. The clearest shift appears from late February onward, when the number of withdrawals begins to rise sharply after a quieter stretch earlier in the quarter. Several sessions printed more than 4,000 outflow transactions, while some spikes came close to 6,000 in a single day. That detail matters because exchange outflows are commonly read as a sign that holders are moving tokens off trading venues and into other wallets, often for storage rather than immediate sale. It is not a perfect one-to-one measure of conviction, but in market structure terms it usually points more toward accumulation than distribution. Darkfost argued that the composition of those flows is just as important as the headline number. “It is also worth noting that most of this activity is driven by transactions ranging between 1,000 and 100,000 XRP, which typically corresponds to mid-sized investors rather than very large whales,” he said. “This type of activity is generally interpreted as a positive signal. An increase in outflow transactions often suggests that investors are withdrawing their tokens from exchanges to hold them elsewhere, which can indicate a gradual accumulation phase.” Related Reading: XRP Ecosystem Enters Regulated UAE Market With Historic Approval That leaves XRP in an interesting spot. The price action itself still looks rangebound rather than impulsive, and the white line on the chart shows no decisive breakout yet. But the underlying behavior on Binance suggests that some market participants are using this period of compression to build positions instead of exiting. The distinction is important. A market can trade sideways for weeks or months without saying much on its own. Sideways price action paired with rising exchange withdrawals, however, gives that same range a different interpretation. It suggests the balance between available sell-side liquidity and long-term holding behavior may be shifting, even if that shift has not yet translated into a clean price expansion. For now, the main question is the one Darkfost raised directly: whether this accumulation phase is strong enough to push XRP out of its current band and “potentially reignite a bullish trend in the coming months.” Until that happens, the range remains intact. But if outflows continue to climb while price holds steady, traders will likely keep watching for signs that the consolidation is less a ceiling than a base. At press time, XRP traded at $1.32.

With the Ethereum price struggling around the $2,000 support, the question of when the digital asset will hit a bottom has continued to linger among investors. Naturally, a bottom is largely based on the Bitcoin price, setting the tone for the entire market. However, a crypto analyst has also suggested things to look out for that could help to confirm that the Ethereum price has actually hit a bottom and will begin to move upward once again. Watch Out For The Ethereum Close Above $2,100 For now, the Ethereum price is still trending below $2,100, and crypto analyst Rawl has called this out as the next important level to break. Given the fact that the Ethereum price had fallen below $2,400 initially, but then didn’t make a complete weekly close, it suggests that this could be a takeout. Related Reading: The Crowd Is Bearish On Bitcoin, But History Says That’s Bullish Going by this, the Ethereum price now needs to actually make a close above $2,100 on the weekly chart to confirm if this is the bottom or not. Since the cryptocurrency completed the last week without making this close, then it moves into this week for another chance to make the close. As the crypto analyst explains, a close above $2,100 would confirm the local bottom, setting the stage for the next price increase. The first move is expected to propel the altcoin as high as $2,400 in the primary move. However, the move is not expected to end there. For a secondary move, Rawl points to a climb to $2,800-$3,000, and hitting the top of this prediction would mean that the Ethereum price would rise 50% from the current level at the time of this report. “So the plan remains the same, we will likely stay choppy here before properly breaking above 2,100 and heading toward 2,800–3,000,” the analyst stated. Bears Could Still Take Over Just like with any scenario, there is still the possibility that the Ethereum price does not make this weekly close and ends up falling below it. In this case, it would put the bears back in control, likely triggering a sustained decline that would keep the cryptocurrency’s price below the $2,000 level. Related Reading: Bitcoin Last Line Of Defense Revealed: Can BTC Price Still Go To $40,000? Even in the case where the Ethereum price does close above $2,100 and completes the projected rally, the crypto analyst says this is only preceding a larger decline. In a previous post, the analyst had pointed out this possible large correction, but then posits that the Ethereum price could continue to rally and likely hit $6,500-$8,000 for a new peak.

As Bitcoin (BTC) retests a crucial level after breaking down of a bearish pattern, an analyst has suggested that the flagship crypto’s final correction before the next bull market could start in the coming days. Related Reading: Ethereum Could Hit $40,000 And Beat Bitcoin, Standard Chartered Says Start Of ‘Final Washout’ Is Days Away In a Monday analysis, market observer Ali Martinez affirmed that Bitcoin’s final leg down before the next bull run could be around the corner based on the flagship crypto’s past cycle’s behavior. The analyst explained that historically, the crossover between BTC’s 50 and 200 Simple Moving Averages (SMAs) has marked the “‘absolute bottom’ of every major cycle since 2014.” Over the past 12 years, whenever these two lines crossed on the three-day chart, it has consistently signaled the start of the “final washout” before the next bull market begins. In 2014, 2018, and 2022, Bitcoin had already declined by 50%-72% from its cycle peaks when the 50- and 200-SMAs crossed. 23-33 days after the crossover, the cryptocurrency continued its correction, retracing another 45%-52% before bottoming. In 2022, “another lower low formed 156 days later, completing the bear structure and opening the door for the next bull market.” Now, Bitcoin has already seen a 52% correction from its October 2025 peak, while the SMAs crossed over on February 27. “As of today, we are exactly 30 days into this signal,” the analyst detailed, adding that “If history ‘rhymes,’ we are likely entering the Final Accumulation Window of this cycle within the next 3 to 6 days.” Martinez noted that while the final leg down could be intimidating, history has shown that the crossover is the “Golden Opportunity” for long-term investors. Based on its 40%-50% “resets,” the analyst suggested two main accumulation zones: the $40,000 and $30,000 levels. Structurally, this setup has historically aligned with the last major downside move before a generational macro bottom forms. (…) The countdown to the next vertical move has begun. Bitcoin Bear Flag Breakdown Confirmed? After closing the week around the $66,000 mark, Bitcoin has surged to the $67,000-$68,000 area to retest a crucial level from below. The flagship crypto has been trading between $62,000-$74,000 for nearly two months, developing a bearish formation during this period. Notably, BTC has formed a bearish flag pattern on the daily timeframe, retesting the formation’s lower and upper boundaries multiple times since early February. Following last week’s correction, the cryptocurrency retraced over 10% from its recent highs to a four-week low of $65,000 on Sunday. Related Reading: The Last Time Bitcoin Sentiment Was This Bad Was 2022, But There Was A Silver Lining Amid this performance, Bitcoin lost the lower boundary of its bear flag formation, risking a second leg down toward lower levels. Analyst Crypto Jelle noted that the cryptocurrency is currently retesting the formation from below after today’s bounce, which could confirm that the pattern’s support has turned into resistance if BTC price is rejected. In addition, the market watcher pointed out that the cryptocurrency’s bear market lows have historically formed below the Fibonacci 0.618 retracement levels, which could place BTC’s bottom below the $57,000 area. “Is this time different? Doubt it,” Jelle concluded. Featured Image from Unsplash.com, Chart from TradingView.com
