Bitcoin investors have been locking in sizable gains over the past week, with on-chain data indicating roughly $5.46 billion in realized profits as BTC trades just below a major resistance band. Glassnode figures shared by analyst Ali Martinez on April 25 show repeated bursts of profit-taking in recent sessions, including multiple intraday spikes nearing or above $1 billion. The pattern suggests systematic selling into strength as Bitcoin pushes toward the top of its current range, rather than fear-driven capitulation. Bitcoin has been trading around $77,000 to $78,000, sitting beneath the widely watched psychological resistance zone between $78,000 and $80,000. The asset is also on track for a fourth straight weekly advance, even as the same ceiling has repeatedly capped upside momentum, leaving the $80,000 level as a key pivot for the next leg. The profit-taking fits with a broader consolidation phase: instead of sharp selling pressure, the market has shown measured distribution, with advances unfolding in stages as price approaches resistance. The behavior points to a more mature risk-managed backdrop. Martinez also argues that Bitcoin's recent structure is increasingly shaped by trader behavior rather than fixed technical levels. In prior cycles, a breakout over the previous 123 days preceded an approximate 36% decline, followed by a 75-day consolidation that led to another nearly 39% drop. By contrast, the current 82-day channel signals stabilization, with BTC rebounding toward the upper boundary near $78,000 after finding support in the $58,600 to $70,000 area. The shifting channels underscore that support and resistance tend to hold only when buyers and sellers remain committed; as liquidity and positioning change, older levels can weaken and new ones emerge. As of press time, Bitcoin was at $77,636, up about 0.14% over the past 24 hours and roughly 1% on the week. A sustained breakout above $80,000 could set the stage for further gains, with some forecasts calling for a move into the $85,000 to $90,000 range.

Spot Bitcoin ETFs logged more than $823 million in net inflows over the past week, underscoring a sustained run of daily additions. The continued inflow streak points to strengthening institutional demand for Bitcoin exposure through regulated fund vehicles.

Huoxing Finance reported that Project Eleven has awarded today's QDay Prize to researcher Giancarlo Lelli after he derived a 15-bit elliptic-curve private key from its public key using publicly available quantum hardware. The result is the largest public demonstration of its kind so far, marking a 512-fold improvement over a 6-bit demonstration in September 2025. Lelli used a Shor's-algorithm variant adapted to the elliptic curve discrete logarithm problem (ECDLP), the mathematical basis of Bitcoin's signature scheme, running on hardware with roughly 70 qubits. Despite the milestone, no known quantum computer can break real Bitcoin wallets today; Bitcoin's 256-bit elliptic-curve security remains well beyond current quantum capabilities. Risk timelines are still being pulled forward. On March 31, Google reduced its resource estimates for ECDLP256 and set a post-quantum cryptography migration target for after 2029. Cloudflare has since taken a similar stance, and the UK's NCSC has outlined migration milestones spanning 2028 to 2035. On-chain data indicates around 6.93 million BTC may face potential quantum exposure because their public keys are already revealed. Within the Bitcoin community, BIP 360 and BIP 361 have been proposed to encourage quantum-resistant output types, though coordinating any network-wide shift across a decentralized system remains the central hurdle.

Independent researcher Giancarlo Lelli has received the QDay Award and a 1 BTC prize from quantum-safe startup Project Eleven after successfully breaking a cryptographic key tied to Bitcoin security, Odaily Planet Daily reported. Lelli used publicly available quantum hardware and a modified version of Shor’s algorithm to crack a 15-bit cryptographic key from a space of 32,767 possible combinations. Project Eleven said the result marks a 512-fold jump in difficulty from the prior benchmark, a 6-bit key cracked in September 2025. Project Eleven CEO Alex Pruden warned that the resources needed for these attacks are trending lower, while roughly 6.9 million BTC are believed to sit in vulnerable static addresses—including about 1 million BTC attributed to Satoshi Nakamoto. The Bitcoin community has already floated BIP360 to add quantum-resistant address formats. Other networks and platforms, including Ethereum, Ripple, and Tron, have also started outlining migration plans toward post-quantum protections.

CryptoSlate reports that Project Eleven awarded researcher Giancarlo Lelli the QDay Prize on April 24 after he derived a 15-bit elliptic-curve private key from a public key using publicly available quantum hardware. The result is the largest public demonstration so far and marks a 512-fold leap from a 6-bit proof-of-concept shown in September 2025. Lelli used a Shor's algorithm variant adapted to the elliptic curve discrete logarithm problem (ECDLP), the mathematical backbone of Bitcoin's signature system, running on hardware with roughly 70 qubits. No existing quantum machine is capable of compromising real Bitcoin wallets. Bitcoin's 256-bit elliptic-curve security remains well beyond current quantum capabilities. Even so, timelines are moving up: on March 31, Google reduced its resource estimates for ECDLP256 and pointed to post-quantum cryptography migration targets after 2029. Cloudflare soon echoed that stance, while the UK's National Cyber Security Centre (NCSC) has set migration milestones spanning 2028 to 2035. On-chain data suggests about 6.93 million BTC could be exposed to future quantum threats because their public keys are already visible. Within the Bitcoin community, proposals BIP 360 and BIP 361 aim to accelerate adoption of quantum-resistant output types. The hardest part remains execution—coordinating a network-wide transition in a decentralized system.

Bitcoin spot ETFs recorded net inflows on each trading day this week, bringing weekly net inflows to over $823 million.

CoinDesk reported that on April 24, spot Bitcoin ETFs recorded $14.45 million of net inflows and spot Ethereum ETFs took in $23.38 million, bringing total inflows for the day to $37.8 million. Bitcoin slipped toward $60,000 in April, and the market is pricing a 0% "YES" probability for BTC touching $60,000 this month. Ongoing ETF buying has lowered the perceived odds of a drop to that level, even as overall trading conditions remain subdued. With tensions between the U.S. and Iran escalating, some institutional investors appear to be treating Bitcoin as a safe-haven allocation. For June 30, the market assigns a 3.5% "YES" chance that Bitcoin sets a new all-time high, up from 3% the prior day. The low reading suggests traders remain skeptical that a fresh record can be reached before July. Longer-dated pricing is more constructive: September 30 is at 11% "YES" and December 31 at 18.5% "YES", implying sustained ETF inflows could support a more extended bullish thesis. Ethereum’s $23.38 million inflow points to rising institutional interest, even as activity remains muted and ETH trades around $4,000 in April. At Bitcoin’s all-time-high price, 24-hour volume totaled $8,027 in face value, with $917 in actual USDC traded. Order-book depth suggests a 5-point move on June 30 required $959 in orders, indicating moderate liquidity. The biggest move was recorded on September 30 at 3:34 PM, when a large order lifted the price by 2 points. At current prices, "YES" shares purchased at the June 30 high are valued at $1, a 28.57x return. For that wager to be sustained, traders will be watching for continued capital inflows and any easing in geopolitical risk. Market participants are also monitoring any updates from BlackRock or Fidelity on ETF strategy, along with Federal Reserve signals on interest-rate policy, all of which could shift sentiment.

BlockBeats reported on April 25 that as Bitcoin moved closer to the $80,000 threshold, on-chain data pointed to aggressive accumulation by large holders, a pattern often seen around major market inflection points. Santiment data show wallets holding between 10 and 10,000 BTC have added about 40,967 BTC since April 10, worth roughly $3.17 billion. By contrast, smaller holders with under 0.1 BTC bought only around 46 BTC over the same period, valued at about $3.56 million. Santiment said this setup—large holders steadily accumulating while retail investors gradually take profits—has historically aligned with stronger medium- to long-term uptrends and can be among the clearest bullish signals. In trading, BTC climbed to $79,327 before easing to around $77,390, up about 8.6% over the past 30 days. Analysts say a clean break above $80,000 could revive sentiment and draw fresh inflows. Bitwise's Head of European Research added that institutional demand is accelerating sharply. Santiment also noted sentiment has shifted from "extreme pessimism" to "strong FOMO," while still sitting in the "fear" zone, suggesting the market has not yet fully overheated.

Bitcoin rose 5% over a choppy week, with energy markets back in focus after oil prices surged, adding uncertainty to the broader economic outlook.
