Bitcoin attracted $933 million into digital asset investment products during the week covered by CoinShares’ April 27 report, comfortably exceeding flows into other individual crypto assets. Bitcoin accounted for the largest asset-level inflow as total digital asset investment products recorded $1.2 billion…

U.S. spot Bitcoin ETFs swung from a strong start to a sharp reversal by Jan. 8–9, 2026, posting a three-day net outflow estimated at roughly $934.8 million to $1.128 billion. Those redemptions effectively erased the $1.16 billion in inflows from the first…
BlackRock executed a concentrated three-day purchase of Bitcoin and Ethereum totaling $1.027 billion, a move that materially expanded its crypto exposure and put institutional flow dynamics back in focus. The scale and timing of the buying cycle shifted attention toward how large…
Strategy disclosed a $17.44 billion unrealized loss on its Bitcoin holdings for the fourth quarter of 2025 after a sharp drop in Bitcoin’s market price and the move to mark-to-market accounting. That headline paper loss was partially cushioned by a $5.01 billion…
Potential U.S. control of Venezuela’s estimated $17 trillion in oil reserves as a strategic inflection point for the petrodollar system, de-dollarization trends, and the macro backdrop for Bitcoin. The shift would have immediate implications for currency flows, institutional treasury allocation, and risk…
Metaplanet is leaning hard into a Bitcoin-first treasury identity, and the numbers it put on the table for 2025 are designed to make that unmistakable. The company reported a 568.2% year-to-date BTC yield for 2025 and disclosed total holdings of 35,102 BTC,…
Institutions aren’t treating altcoins like a pure “buy-and-hope” trade anymore. More and more of the playbook that used to live almost exclusively in Bitcoin options is being applied across hundreds of tokens to control volatility and pull yield from the same positions.…
Sberbank has issued Russia’s first corporate crypto-backed loan to Bitcoin miner Intelion Data, using mined Bitcoin as collateral. The pilot—while keeping financial terms undisclosed—signals an initial move toward integrating mined digital assets into ruble-denominated corporate lending. Sberbank accepted Intelion Data’s mined Bitcoin…
Bitcoin mining difficulty is closing in on record territory after the network’s final adjustment of 2025, hitting 148.2 trillion. Difficulty is projected to reach roughly 149–150 trillion by early January 2026, a shift that immediately tightens miner economics and raises operational risk.…
Investors are recalibrating allocations as copper’s 2025 rally outpaced Bitcoin, highlighting a renewed preference for assets tied to tangible industrial demand. The divergence between copper’s steady gains and Bitcoin’s late-year retracement is reshaping risk-return narratives for portfolio managers, custodians, and compliance teams.…
The Cat proposal is an early draft debated in Bitcoin developer forums in late December 2025 that would mark certain historical small unspent transaction outputs (UTXOs) as permanently unspendable to reduce UTXO bloat. The debate is framed as a choice between a…
Wintermute concludes that a broad-based altcoin rally is unlikely as Bitcoin captures most market capital. With Bitcoin dominance sustained in the mid-50s to mid-60s and the Altcoin Season Index at 20–30, the data points to a market-wide rotation away from smaller tokens,…
BlackRock named its iShares Bitcoin Trust (IBIT) as one of three core investment themes for 2025, putting a regulated Bitcoin ETF in the same strategic bucket as Treasury bills and the “Magnificent Seven” tech stocks. The message is that BlackRock is leaning…
Galaxy Digital projects Bitcoin could reach $250,000 by the end of 2027, tying its forecast to institutional adoption and a potential easing in global monetary conditions. Galaxy simultaneously characterizes 2026 as “chaotic and too uncertain to predict,” positioning the near term as…
U.S. bitcoin ETFs drew a reported $457.3 million in net inflows on December 18, 2025, the largest single-day intake in more than a month and a fresh signal of renewed institutional interest in regulated BTC exposure. The move coincided with Bitcoin’s market…
Japan's 10-year government bond yield has climbed to 1.98%, reaching an 18-year high that signals a significant departure from decades of ultra-loose monetary policy. This shift is immediately affecting markets for gold, silver, and Bitcoin as the Bank of Japan prepares a…
Options-market measures show a distinct bullish tilt for Ethereum relative to Bitcoin, where traders appear to seek less downside protection for ETH than for BTC. The divergence, visible in skew and put–call ratios, coincides with recent protocol upgrades, growing institutional activity and…

Daily TVL observations use their own scale. USD prices and protocol coverage can change the total without a matching change in token deposits. Observed · 16 Sep 2026, 12:24 UTC.
Fees describe current transaction demand in the observed snapshot. TVL describes a separate slice of DeFi activity. Neither is a complete measure of Bitcoin adoption, investment demand or network security.

Open release notes ↗THE PROJECT IN PERSPECTIVE
Bitcoin is an open network for transferring value without a central operator. Its native asset, BTC, is used for transfers and transaction fees. Proof-of-work miners propose blocks, while validating nodes enforce the protocol’s rules.
The protocol, the asset and the businesses built around them are related but distinct. This dossier brings together newsroom coverage, selected software publications and network observations so those different stories can be followed in context.
