Grayscale Investments, the world’s largest digital currency asset manager, executed a significant institutional cryptocurrency transfer today, depositing 6,157 Ethereum tokens worth approximately $13.74 million to Coinbase Prime. This substantial movement, detected by blockchain intelligence platform Arkham Intelligence, represents one of the most noteworthy institutional crypto transactions of the month and signals potential strategic repositioning within the digital asset ecosystem. The transaction occurred precisely two hours before market analysts began tracking the movement, highlighting the sophisticated timing mechanisms employed by major institutional players.

Grayscale Investments, the world’s largest digital asset manager, transferred 6,157 ETH (approximately $13.74 million) to Coinbase Prime, a leading institutional crypto platform. The transaction, tracked by Arkham Intelligence, stands out as one of the notable institutional moves this month and may indicate strategic positioning.

The transfer occurred during U.S. trading hours (10:42 AM ET), was confirmed within three minutes, and had a fee of around 0.02 ETH — suggesting a planned, non-urgent operation. Funds were sent from a verified Grayscale wallet to a confirmed Coinbase Prime institutional address.

Coinbase Prime provides institutional-grade services including custody, trading, compliance, insurance, and reporting. Using this platform may signal preparation for portfolio rebalancing, client redemptions, or new strategic moves.

Historically, similar transfers have preceded key events such as fee changes, market shifts, or network upgrades. However, there is no direct evidence linking this move to immediate price action, and the market reaction so far remains limited.

It’s important to note that institutional players operate differently from retail investors — they focus on regulation, liquidity, risk management, and operational efficiency. Asset transfers between platforms are often about optimization, not speculation.

Overall, this move reflects a broader trend: the crypto market is increasingly integrating into the institutional financial system, supported by advanced infrastructure and growing interest from major players.

The acquisition is designed to strengthen the company’s ability to connect traditional fiat networks with onchain transactions, as demand for stablecoin-based payments continues to grow globally.

Strategic Push Into Stablecoin Infrastructure

The acquisition signals Mastercard’s intent to position itself at the center of the emerging stablecoin payments ecosystem, where traditional finance and blockchain-based systems increasingly intersect.

BVNK, founded in 2021, provides infrastructure that allows businesses to send and receive payments using both fiat currencies and stablecoins across multiple blockchain networks. Its platform supports a wide range of use cases, including cross-border payments, treasury operations, and business-to-business transactions.

By bringing BVNK into its ecosystem, Mastercard is effectively acquiring a ready-built bridge between conventional payment rails and decentralized financial infrastructure.

From Partnerships to Full Integration

Mastercard’s move builds on a broader strategy that has seen the company assemble a large network of crypto and fintech partners.

Through its Crypto Partner Program, Mastercard has already brought together more than 85 companies, including major players such as Binance, PayPal and Ripple, to accelerate the integration of blockchain-based payments into global commerce.

At the core of this effort is Mastercard’s Multi-Token Network (MTN) – a private settlement layer designed to connect tokenized bank deposits and regulated stablecoins across financial institutions.

The addition of BVNK strengthens this infrastructure by providing direct access to real-world payment flows, enabling businesses to seamlessly move between fiat and digital currencies.

Competition Intensifies for Stablecoin Rails

The deal also highlights intensifying competition among global payment firms to secure a foothold in stablecoin infrastructure.

BVNK has attracted backing from several major financial institutions in recent years. Visa invested in the company through its venture arm in 2025, while Citigroup’s Citi Ventures also participated in funding rounds that pushed BVNK’s valuation above $750 million prior to the Mastercard deal.

Hana Financial and Standard Chartered Deepen Global Alliance With Focus on Digital Assets

Notably, Coinbase had previously explored acquiring BVNK in a proposed $2 billion transaction, but the deal was abandoned in late 2025 after due diligence, with no official reason disclosed.

Mastercard’s successful acquisition now positions it ahead of both traditional payment rivals and crypto-native firms in building integrated payment infrastructure that spans both worlds.

Stablecoins Move Toward Mainstream Adoption

The acquisition comes as stablecoins increasingly gain traction as a practical payment medium, particularly for cross-border transactions where speed and cost efficiency are critical.

Monthly crypto transaction volumes reached approximately $969.9 billion in August 2025, and industry projections suggest that figure could approach $1 trillion per month by late 2026.

Mastercard’s network, which already spans more than 150 million merchant locations worldwide, provides a massive distribution channel for stablecoin-based payments.

By integrating BVNK’s infrastructure, Mastercard aims to enable businesses and consumers to transact seamlessly using digital assets while maintaining the familiarity and reliability of traditional payment systems.

Outlook

Mastercard’s acquisition of BVNK represents a clear escalation in the race to build the financial infrastructure underpinning the next generation of payments.

Rather than treating crypto as a parallel system, the company is betting on convergence – where stablecoins, tokenized deposits and traditional currencies coexist within unified networks.

Strategy buys 22,337 Bitcoin in its latest treasury move, lifting its reported holdings to 761,068 BTC. The size of the purchase reinforces the company’s long-running accumulation strategy, while the lack of directly retrieved filing text means some details still rely on same-day secondary reports tied to Strategy’s reported March 16, 2026 disclosure.

Secondary reports published on March 16 said Strategy bought 22,337 BTC for about $1.57 billion at an average price of $70,194 per coin, figures attributed to the company’s latest disclosure pattern and the related Strategy press release page. Coinwy could not directly inspect the full filing text in this run, so the article stays narrowly focused on the figures repeated across credible reports and the official URL structure.

Strategy’s Latest Buy Adds 22,337 BTC to Its Treasury

The reported purchase is large even by Strategy’s usual standards. At roughly $1.57 billion, it extends the company’s habit of using recurring capital raises to keep increasing its Bitcoin position rather than treating the asset as a short-term trade.

The arithmetic is consistent with Strategy’s previous update. The company said on March 9 that it held 738,731 BTC, and adding 22,337 BTC brings the total to 761,068 BTC, the balance reported for March 15 in follow-up coverage linked to the March 16 disclosure.

That consistency matters because the primary source was only partially verified in this environment. The official page URL fits Strategy’s established press-release pattern, but the exact filing metadata and SEC accession details were not independently confirmed here.

Total Holdings Reach 761,068 BTC

If the reported figures hold, Strategy’s aggregate acquisition cost now stands near $57.61 billion, with an average all-in purchase price of about $75,696 per Bitcoin, according to reporting tied to the company’s latest update. The newest tranche was bought below that average, which modestly improves the blended cost basis.

The new total also shows how central Bitcoin remains to Strategy’s corporate identity. The company has continued adding to its reserves through different market conditions, and each weekly-style update gives investors another checkpoint on how aggressively management is sticking to that approach.

For readers tracking corporate adoption, the headline number is the cumulative balance, not just the weekly buy. A treasury measured in the hundreds of thousands of BTC keeps Strategy at the center of discussions about public-company exposure to Bitcoin and the concentration risks that come with it.

Why the Market Watches Strategy Accumulation So Closely

Supporters of the strategy see another sign of conviction. Buying more Bitcoin while keeping the latest average purchase price below the portfolio-wide average supports the case that management is still executing a long-term reserve-asset thesis rather than reacting to short-term price swings.

Critics focus on a different risk. Each new purchase deepens Strategy’s dependence on Bitcoin’s market value and keeps attention on how future financing, volatility, or a prolonged drawdown could affect the balance sheet and investor sentiment.

That is why weekly accumulation updates tend to travel beyond the crypto press. They feed into broader debates over institutional ownership, a theme also reflected in Coinwy’s recent coverage of crypto fund inflows and arguments that Bitcoin’s resilience increasingly reflects an ownership shift toward larger holders.

The latest report does not, on its own, settle the bull-versus-bear debate around Strategy’s model. It does show that the company is still accumulating at scale, and it keeps the next official filing or press update in focus for investors who want direct confirmation of the full terms.

US spot Bitcoin exchange-traded funds (ETFs) logged their first five-day inflow streak of 2026, bringing in roughly $767.32 million this week.

The funds recorded $180.33 million in net inflows on Friday, extending the run of positive flows that began earlier in the week. The strongest day of the streak came on Tuesday, when spot Bitcoin (BTC) ETFs attracted $250.92 million, according to data from SoSoValue.

The last time the funds saw a comparable streak was in late November 2025, when spot Bitcoin ETFs logged five consecutive days of net inflows from Nov. 25 to Dec. 2, bringing in a combined $284.61 million.

Overall, the ETFs now hold $91.83 billion in net assets, with cumulative net inflows reaching $56.14 billion and roughly $4.93 billion in total value traded on the day.

Ether ETFs see 4-day inflow streak

Meanwhile, US spot Ether (ETH) ETFs recorded $26.69 million in net inflows on Friday, extending a four-day run of positive flows. The streak began on Tuesday, when the funds added $12.59 million, followed by $57.01 million on Wednesday and a stronger $115.85 million on Thursday, the largest inflow during the period.

The four-day stretch has brought roughly $212.14 million into spot Ether ETFs, reversing the outflows seen earlier in March. As of today, cumulative net inflows into US spot Ether ETFs stands at $11.79 billion, while total net assets across the funds reached $12.26 billion, with about $1.30 billion in value traded on the day.

The recent stretch marks the first sustained inflow run for spot Bitcoin and Ether ETFs this year after a volatile start to 2026 that saw several days of heavy outflows across the products.

Bitcoin range-bound as Middle East tensions rise

Rising tensions in the Middle East and volatility in energy markets are weighing on global risk sentiment. According to Bitunix analysts, escalating conflict around the Strait of Hormuz and elevated oil prices have increased macro uncertainty and reduced expectations for aggressive Federal Reserve rate cuts, prompting investors to focus on short-term liquidity rather than long-term risk exposure.

Against this backdrop, Bitcoin remains range-bound. Bitunix said derivatives liquidation heatmaps show a key short-liquidity cluster near $71,300, which is acting as near-term resistance, with a larger concentration between $72,000 and $73,500.

On the downside, liquidity support sits around $69,000, with deeper long liquidation levels near $68,800, suggesting BTC may continue consolidating unless macro catalysts trigger a breakout.

Nvidia, the firm whose chips currently power a large portion of the world’s artificial intelligence infrastructure, is moving farther into the development of AI software and models, indicating that it aims to be much more than just a manufacturer of hardware.

A portion of the plot is revealed by the numbers. Analysts predict that Nvidia’s annual revenue will surpass $358.7 billion in 2026 after rising from $26.9 billion in 2022 to $215.9 billion in 2025.

The shares of ChatGPT have increased by around 990% from the company’s November 2022 start.

Nvidia announced intentions to invest $26 billion over the next five years to assist the development of open-source AI big models in filings submitted to the U.S. Securities and Exchange Commission.

The company’s appeal has never been just about chips. Its CUDA software platform, which allows customers to get the most out of its graphics processing units, has been central to its rise.

Justin Boitano, Nvidia’s vice president of enterprise platforms, pointed out that most of their staff is software engineers, a fact that often gets overlooked.

Nvidia’s new model takes a middle road

To build on that software side, Nvidia recently released a new open-source AI language model called Nemotron 3 Super. The model is built for enterprise-grade AI systems that involve multiple AI agents working together.

It carries 120 billion parameters and uses a design called Mixture-of-Experts.

One of its key features is a context window of up to one million tokens, meaning it can process an entire book or thousands of pages of financial records in a single run.

Nvidia has taken what might be called a middle road with this model.

Unlike OpenAI, which keeps its models closed, or Meta, which fully opens its Llama models, Nvidia will release the model’s key parameters publicly. Businesses and developers can download and run them for free, or adjust them to fit their own needs.

If Nvidia can hold onto its lead in hardware and grab 10% of the foundational model market, financial analysts say the move could bring in an extra $50 billion in yearly revenue within three years.

Partners build out the hardware side

On the hardware deployment side, Nvidia does not build data centers itself. Partners, including Dell, Hewlett Packard Enterprise, and Foxconn do that work.

Arthur Lewis, who heads infrastructure at Dell, said his company assisted one customer set up 100,000 GPUs in just six weeks.

Concurrently, NTT DATA revealed a plan to implement what it refers to as “AI factories powered by Nvidia hardware.” These are complete configurations that integrate governance systems, software tools, infrastructure, and data. The program makes use of Nvidia’s NeMo and NIM software tools in addition to its hardware. A cancer research hospital that uses Nvidia platforms for radiology and diagnostics, a car parts supplier that uses Nvidia-powered cloud services to reduce production setup time from months to days, and a U.S. manufacturer currently testing battery production lines using Nvidia-accelerated simulation are just a few examples of early customer results.

Kari Briski, Nvidia’s vice president of enterprise generative AI software, noted that building these cutting-edge models puts enormous pressure on storage, networking, and computing systems, and that pressure helps shape the direction of future hardware.

CEO Jensen Huang described AI as more akin to fundamental infrastructure rather than a software fad.

“AI is one of the most powerful forces shaping the world today,” Huang stated. “It is not a clever app or a single model; it is essential infrastructure, like electricity and the internet.”

Huang described the AI stack in five layers: energy at the base, then chips, then physical infrastructure such as land and cooling systems, then AI models, and finally applications at the top, where he said actual economic value gets created, through things like drug discovery, industrial robots, and self-driving vehicles.

He acknowledged the build-out is still in early stages.
A few hundred billion dollars have been spent so far, but Huang said the total will require trillions, calling it potentially the largest infrastructure build-out in human history.

He added that AI models have recently crossed a key line, becoming reliable enough to be widely useful, and that open-source models are helping speed up adoption across the board.

Solana continues to lead in stablecoin transfers, outpacing rival blockchains and establishing itself as a critical settlement layer for global payments. Over the past 365 days, Solana processed $2.62 billion in stablecoin transfers, nearly double Polygon’s $1.2 billion and Base’s $0.7 billion.

The blockchain’s stablecoin transfer volume now accounts for 46% of all activity among comparable networks, reflecting broad adoption across DeFi, cross-border payments, and everyday transactions. Year-over-year, Solana’s payment volume grew 755%, almost three times the median growth rate of peer chains and leading fintechs.

Ecosystem adoption accelerates

Solana’s network is not just Processing transfers; it is hosting live payment infrastructure for major fintech and financial institutions. Companies including Visa, Stripe, Worldpay, Western Union, PayPal, Revolut, and Cash App are leveraging Solana for settlement operations. This adoption spans 14+ stablecoins, including USDC, USDT, PYUSD, and state-backed tokens from Wyoming, Kazakhstan, and Bhutan. Corporate treasury management is also supported via Altitude, enabling seamless settlement for enterprise payments.

Unlike legacy payment rails such as SWIFT and ACH, which operate under banking hours and carry high fees, Solana provides near-instant, 24/7/365 settlement with minimal costs. Its speed and low fees are driving measurable adoption, giving financial institutions operating leverage and reducing capital idle time.

Stablecoins as the on-chain economy indicator

Stablecoin transfer volumes serve as a key metric for onchain economic activity. Solana’s dominance highlights its growing role as the backbone of digital payments. The combination of robust network performance, real-world payment adoption, and rapid growth positions Solana as a leading blockchain for stablecoins and enterprise-grade financial infrastructure. Analysts suggest that Solana’s continued expansion in stablecoin settlement could reshape how global payments are executed onchain.

Meanwhile, Solana currently dominates the agentic finance space, accounting for roughly 80 per cent of agentic transactions in early 2026. Its architecture supports sub-second finality and extremely low fees, enabling AI agents to perform thousands of micro-transactions profitably.

Stablecoins are evolving from a niche crypto trading tool into a potential layer of global financial infrastructure, according to Australian investment bank Macquarie.

While most U.S. dollar-denominated stablecoin activity, mainly in Tether’s USDT and Circle’s USDC, still comes from crypto trading, accounting for about 90% of volume, the bank said adoption is expanding across payments, remittances, treasury operations and tokenized assets, increasingly linking traditional finance with decentralized finance.

"Stablecoin adoption is making strides in cross-border remittances, but adoption as form of payment still has room to grow, presenting an attractive total addressable market (TAM) opportunity," analysts led by Paul Golding said in the Monday note.

Regulatory progress is helping drive the shift. The analysts pointed to developments such as the U.S. GENIUS Act, Europe’s MiCA framework and emerging Asia-Pacific regulations as factors pushing stablecoins from speculative uses toward institutional settlement tools.

Stablecoins are cryptocurrencies designed to maintain a fixed value, typically pegged to the U.S. dollar, and are widely used across digital asset markets for trading, payments and transfers.

Tether’s USDT is the largest stablecoin by market value and trading volume, serving as a key source of liquidity across crypto exchanges, while Circle’s USDC is the second largest and is widely used in institutional and decentralized finance applications. Together, the tokens underpin much of the crypto market’s activity and are increasingly being explored for payments, remittances and settlement.

Stablecoin growth has been rapid. Macquarie estimates the combined market capitalization of major coins at about $312 billion as of March 2026, up roughly 50% year over year and representing about 7%–8% of the total crypto market.

Transaction activity is rising even faster. Adjusted stablecoin transfer volume reached roughly $11 trillion in 2025, the bank said, suggesting onchain dollars are becoming a meaningful economic tool both within crypto markets and in some real-world payment corridors.

Payments networks and fintech firms are beginning to integrate the technology. The report noted that Visa (V) and Mastercard (MA) now support USDC settlement, allowing card obligations to be discharged onchain.

Banks are experimenting with similar systems. Macquarie pointed to initiatives including JPMorgan’s JPMD tokenized deposit product, Citi’s Token Services and tokenized deposit pilots at HSBC as evidence that blockchain-based settlement is gaining traction among large financial institutions.

On March 9, 2026, OpenAI announced the acquisition of cybersecurity startup Promptfoo. The deal is aimed at strengthening the security of large language models (LLMs) and autonomous AI agents. Promptfoo’s technology will be integrated into the enterprise platform OpenAI Frontier to improve the reliability and protection of AI systems used in business environments.

The development of AI agents capable of performing complex tasks autonomously creates major opportunities for businesses. However, it also introduces new security risks. Malicious actors may attempt to exploit such systems to access corporate data, manipulate automated workflows, or disrupt operations. As a result, security has become one of the key requirements for enterprise adoption of artificial intelligence.

Promptfoo was founded in 2024 by security experts Ian Webster and Michael D’Angelo. The company developed tools designed to identify vulnerabilities in language models and test AI systems for potential security risks. According to the company, more than 25% of Fortune 500 companies already use its solutions to stress-test their AI implementations. Despite strong market adoption, the startup raised about $23 million in funding and was valued at approximately $86 million. The financial terms of the acquisition were not disclosed.

Promptfoo’s technology focuses on identifying vulnerabilities in AI systems. Its tools allow automated security testing, simulate potential attacks, and analyze complex AI-agent workflows for hidden risks. The platform will also enable continuous monitoring of security and compliance during live operations.

OpenAI also confirmed that it will continue supporting Promptfoo’s open-source tools, helping to establish broader security standards across the AI industry.

The acquisition reflects a broader industry trend: security is becoming a fundamental component of artificial intelligence development. For industries such as finance, healthcare, and government, the reliability and protection of AI systems are now critical requirements.

OpenAI’s move highlights that the future of AI will be defined not only by the power of models, but also by how effectively they can be secured and safely deployed.

Starcloud, an Nvidia-backed orbital data center startup, said it will start mining Bitcoin from space later this year when its second spacecraft is launched, positioning it to become the first company to mine Bitcoin off Earth.

Starcloud “will be the first to mine Bitcoin in space,” the startup’s CEO, Philip Johnston, posted to X on Saturday after revealing its Bitcoin mining ambitions in space in an interview with HyperChange on Thursday.

In the interview, Johnston said running Bitcoin application-specific integrated circuit (ASIC) miners would be “one of the most compelling use cases” of space compute due to it being significantly cheaper than GPUs.

“GPUs are about 30 times more expensive per kilowatt or per watt than ASICs,” Johnston said. “A 1-kilowatt B200 chip, it might cost $30,000. A 1-kilowatt ASIC is like $1,000.”

In the X post, Johnston said Bitcoin mining in space will become a “massive industry” due to how much more economical it is than mining the cryptocurrency on Earth.

“Bitcoin mining consumes about 20 GW of power continuously. It makes no sense to do this on Earth, and in the end state, all of this will be done in space.”

Starcloud was founded in early 2024 to build data centers in space as a solution to address rising energy needs for AI. In November, it launched a satellite with an NVIDIA H100 into orbit, marking the first time a GPU that powerful has ever operated in space.

Its data centers, which comprise around 88,000 satellites, are primarily powered by solar energy.

Sending Bitcoin to Mars

While Johnston’s Starcloud envisions mining Bitcoin in space, tech entrepreneurs Jose E. Puente and Carlos Puente last year came up with a solution to send it across planets.

In September, Puente told Cointelegraph that it is theoretically possible to send Bitcoin to Mars in as fast as three minutes by leveraging an optical link from NASA or Starlink and a new interplanetary timestamping system.

While someone would need to be there to receive it, the Bitcoin transaction would move through space stations — such as antennas and satellites — or even a relay around the Moon before reaching Mars.

They, however, said that mining Bitcoin on Mars would not be feasible due to the latency between the two planets.
