Jensen Huang, NVIDIA CEO: My parents were very strict with me; I was never good enough for them'
The childhood of the head of the most valuable technology company in the world was marked by strict schooling and parents with iron-discipline.

Nvidia has reached a historic milestone by surpassing $5 trillion in market valuation, establishing itself as the reference company in the development of hardware for artificial intelligence. Behind that meteoric growth is Jensen Huang, cofounder and CEO of the company, who attributes much of his way of running the business to the strict education he received during his childhood.

Jensen Huang, NVIDIA’s chief executive officer, shared that his parents were very demanding and that he never managed to meet their expectations.
Born in Taiwan in 1963, Huang immigrated to the United States with his family when he was a child. That life change came with iron discipline, typical of many Asian families, which, according to the executive, ended up shaping his character and the way he understands work. In numerous interviews and conferences, he has explained that his parents never considered an achievement to be final: there was always room to improve, and self-satisfaction was simply not an option.

Bitcoin faces a key test in the US and the market anticipates two price scenarios. Legislative work in the US increases crypto volatility, adding pressure to the bearish trend and investor appetite for digital assets.

The Clarity Act, a key crypto regulation in the US, is at risk of not being approved before Congress’s recess.

Key point The law aims to define the regulation of digital assets between the SEC and the CFTC, but the Senate lacks the necessary votes.

Key point Not being approved would remove a major institutional catalyst, leading to uncertainty and a possible negative impact on Bitcoin.

Wallet of Satoshi puts BTC on the line for a Mario Bros match
Whoever manages to reach 4:54.265 —perfect execution time— will be awarded the 0.21 BTC prize.

The world record is held by a human player known as LeKukie.
Anyone can add additional funds to the prize.

Wallet of Satoshi, one of the most widely used apps for sending and receiving payments with bitcoin (BTC) on both the main network and the Lightning Network (LN), launched a financial and video game challenge by offering a 0.21 BTC reward (equivalent to $13,472 based on current market rates) to the person who can complete a mathematically and physically flawless run of the classic Super Mario Bros in exactly 4 minutes, 54 seconds, and 265 milliseconds.

The proposed record corresponds to the absolute physical limit imposed by the game’s code and architecture released in 1985 for the Any% category, a discipline focused on finishing the video game in the shortest possible time using any allowed shortcut, the competition website explains.

SpaceX delivers its future to Starship with the retirement of Falcon 9
SpaceX limits commercial reservations for Falcon 9 beyond 2028 and focuses its strategy on a Starship that still has no operational track record.

An article by Sana Pashankar and Ed Ludlow. - SpaceX has begun rejecting satellite operators seeking exclusive launches beyond 2028 aboard Falcon 9, according to people familiar with the situation. The decision reflects the size of Elon Musk’s bet on Starship, a vehicle that is still not operational.

The company has also stopped manufacturing some non-reusable components from the Falcon family, including the rocket’s large upper stage, according to one of the sources.

SpaceX loses more than half its value from its peak The euphoria surrounding SpaceX gave way to a violent disappointment. In just a few weeks, the SPCX stock went from being the biggest initial public offering in history to a correction that wiped out hundreds of billions of dollars in valuation. This drop doesn’t only affect shareholders. It also trims Elon Musk’s fortune and revives doubts about the valuations of tech giants—several of which have turned bitcoin into a strategic asset on their balance sheets.

A historic correction in SpaceX’s SPCX stock in the markets
This Thursday, July 23, marks a grim turning point for the aerospace giant’s public listing. During the morning session, SpaceX’s stock (SPCX) slid to hover near the $110.99 mark, trading around $111, before stabilizing slightly above $112. That level represents a net pullback of 18% from the originally set IPO price of $135

Beyond Bitcoin: banks are seriously investing in tokenization
Banks, exchanges and payment companies are accelerating the use of digital assets, such as Bitcoin, even though the new infrastructure still needs to prove that it lowers costs and risks.

Ten years ago, Australia’s largest exchange decided that its future lay in using blockchain technology to clear and settle equity trades. The idea was to leverage the useful parts of cryptocurrency technology, such as Bitcoin, without getting close to the speculation surrounding digital money.

The project ended up like Mark Zuckerberg’s metaverse: it was expensive, progressed slowly, and was ultimately abandoned.

Why it matters: that failure has not kept blockchain out of the spotlight in finance. The difference is that it is no longer just startups or crypto advocates promising transformation. Big banks, exchanges and payment companies are investing real money in the tokenization of securities, 24-hour open markets and dollar-backed digital currencies.

Current situation: JPMorgan Chase converts financial assets into digital tokens; the London Stock Exchange is trying to compete with cryptocurrency platforms through nonstop trading; and Visa is participating in a broad group of financial firms preparing a stablecoin, so called because its value is kept linked to the U.S. dollar.

Robert Ophèle, the former chairman of France’s securities regulator, argues that tokenization is here to stay. In his view, the technology is no longer immature, it is backed by the Trump administration, and financial institutions are devoting substantial resources to its development.

The first blockchain experiments, such as the one in Australia, were an industrial failure, not an intellectual one, he says.

SpaceX again delays an important flight test after going public
Musk added in a separate post that two of the vehicle’s engines would be replaced and removed before the company tries the flight test again.

SpaceX postponed until Friday its next major test of its huge Starship rocket, after it also called off last week’s launch, underscoring the importance of this crucial milestone.

SpaceX had planned to launch at 5:45 p.m. local time on Thursday from its Starbase facilities in southern Texas, but the company delayed the liftoff by a day due to unfavorable weather conditions.

Once it launches, the rocket will carry improved Starlink satellites that, as part of the test mission, will later burn up in the atmosphere.

Starship is central to SpaceX CEO Elon Musk’s ambitions to install data centers in space, expand the Starlink communications network, and send humans to the Moon and Mars. However, its development has been rocky, marked by major setbacks, malfunctions, and delays.

The Starship test is the rocket’s thirteenth flight and the first since SpaceX’s successful initial public offering in June, which raised a record US$86 billion.

Last Thursday, the company halted its flight attempt right at the moment of liftoff, as columns of smoke rose around the launch tower, but the rocket remained in place. Musk later said in a post on X that some of the Starship engines did not ignite, triggering an automatic abort.

Musk added in a separate post that two of the vehicle’s engines would be replaced and removed before the company tries the flight test again.

Coinglass data has revealed that Ripple’s open interest (OI) on Binance has grown, which could lead to a rebound in its value.

On-chain metrics are the best tools for assessing where a cryptocurrency price may be headed. With the growth of Ripple’s (XRP) open interest (OI) on Binance revealed by Coinglass, the price could see a rebound, according to Tadas Klimasevskis at Dailycoin.

Market participants such as Xaif Crypto on X note that the increase in leverage in the futures and derivatives markets occurs at the expense of spot market inactivity—almost as if it were on vacation. The analyst offers a clear example: open interest (OI) surpassed $500 million on Binance in mid-June.

On that occasion, millions of dollars were liquidated before XRP’s price stabilized at $1. The current leverage ratio on Binance is 0.163, the analyst says. Most traders are betting on the upside for XRP, judging by the ratio between long and short positions. Binance customers appear to be the most optimistic, reaching a long-to-short ratio of 2.92.

XRP bears lose $2 million: Is a major move coming?
On the other hand, overall sentiment is ranging from mildly bullish to mildly bearish. With XRP’s price now at $1.14, this has also wiped out some bearish positions, as some crypto investors didn’t expect XRP to stabilize at this level. As a result, $1.95 million of the $2.83 million liquidated over the past 24 hours were tied to short positions.

Micron provided Tesla with a significant amount of memory chips, Musk claims. Tesla continues to rely on Micron to supply it with memory chips while it develops its own semiconductors for its artificial intelligence projects.

Bloomberg — According to Elon Musk, Micron Technology Inc. (MU) recently provided Tesla Inc. (TSLA) with a “significant allocation” of memory chips, which has helped meet the automaker’s demand for an increasingly scarce product.

At a time when memory chips are hard to come by and prices are high, Micron distributed the supply to Tesla under reasonable terms, Musk said during the automaker’s quarterly results conference on Wednesday.

The global expansion of artificial intelligence systems has boosted demand for memory chips, which help computers store and manage data. This frenzy has triggered a widespread shortage that has spread to other industries, driving up prices and testing production capacity.

In the long term, Musk is working to produce his own semiconductors. The billionaire has launched an ambitious program called Terafab, aimed at manufacturing computing and memory chips at an unprecedented scale. The initiative is a joint effort between Tesla and Space Exploration Technologies Corp. (SPCX), two companies where Musk serves as CEO.

For now, Tesla needs Micron and does not have the purchasing power of other customers. Neither Tesla nor SpaceX appears on Micron’s list of the top ten customers, the largest U.S. memory chip maker, according to data compiled by Bloomberg.

Micron representatives did not respond to a request for comment.

Tesla shares fall after missing earnings expectations despite record deliveries and AI investment (NASDAQ:TSLA) Tesla (NASDAQ:TSLA) shares fell more than 5% in pre-market trading this Thursday after the electric vehicle maker posted results below market expectations, as lower profit margins in its auto business and negative free cash flow overshadowed record vehicle deliveries and heavy spending on artificial intelligence.

The results reinforced investors’ concerns about the company’s ability to finance its ambitious technology projects without affecting near-term profitability.

Artificial intelligence investment drives spending Tesla reported capital expenditures of $5.8 billion during the second quarter as part of its strategy to develop autonomous driving, robotics, and artificial intelligence.

CEO Elon Musk acknowledged the scale of these investments by saying: "This is a year of enormous capital spending, though he said it will be necessary to generate incredible returns" in the future.

The company recorded negative free cash flow of $1.1 billion during the quarter, the first in two years Deliveries improve, but margins disappoint The auto business showed a major recovery thanks to a strong rebound in vehicle deliveries, which reached a record 480,126 units and far exceeded market forecasts.

The short sellers of SpaceX accumulate unrealized profits of $15.5 billion while the stock falls below its IPO offering price (NASDAQ:SPCX).

Investors holding short positions in SpaceX (NASDAQ:SPCX) have accumulated estimated unrealized gains of $15.5 billion, as the aerospace company’s shares continue to move away from their all-time highs following its stock market debut, according to Ortex Technologies data cited by Reuters.

The stock is already trading below its initial public offering (IPO) price, reversing much of the enthusiasm that drove its strong performance during its first days on the market.

The stock gives back the gains from the IPO
SpaceX priced its IPO at $135 per share on June 11, 2026, and reached an intraday high of $225.64 just five days later.

However, by the close of July 22, the stock finished at $115.26 after falling 6.7% during the session. That places the price approximately 49% below its all-time high and around 15% below the IPO price.

This pullback has driven a substantial increase in bearish bets against the company.

Kaspa accelerates its quantum-proof shielding with zero-knowledge proofs
The Kii organization claims it has compressed the verification of quantum-resistant signatures into seconds on Kaspa.

The heaviest signature, which took more than 28 minutes to test, dropped to just over 16 seconds.
The function is currently running on Kaspa’s testnet, not on the main network.

A quantum computer powerful enough could, in theory, break the cryptography that today protects Bitcoin and cryptocurrencies.

This is not an imminent threat and not fully resolved yet, but it is one the industry is taking seriously: every bitcoin (BTC), every ether transaction (ETH), or any network based on elliptic curve cryptography relies on certain mathematical problems remaining, for now, impossible to solve for a conventional computer.

On the other hand, a sufficiently advanced quantum computer could change that equation—and with it, the security of the private keys that control funds.

That’s why the U.S. National Institute of Standards and Technology (NIST) standardized three families of digital signatures designed to withstand that scenario: ML-DSA, SLH-DSA, and a variant of Falcon known as FN-DSA, the latter still in draft form.

NVIDIA has found a way to curb the energy use of AI data centers: liquid hotter than a jacuzzi. New Rubin servers can run with coolant at 45°C.

The key is to reduce mechanical refrigeration, fans, and water consumption.
A 100% liquid design aims to pack more computing into less space.

For years, we’ve associated efficient data centers with cold rooms, icy air aisles, and roaring machines to keep servers under control. The expansion of artificial intelligence is forcing us to rethink that image. The next generation of infrastructure doesn’t just have to house more powerful chips—it also needs to keep them running without energy consumption growing at the same pace. In that scenario, NVIDIA is betting on a counterintuitive solution: using a coolant at 45°C, a temperature higher than that of many jacuzzis.

The reason for this shift lies in the scale that AI is reaching. Data centers need to run more and more operations and pack more compute capability into less space, which increases both electricity demand and the amount of heat their systems must manage. Jensen Huang’s company explains that energy efficiency isn’t only about using less power, but about completing more computing work per kilowatt-hour consumed. This metric has become one of the biggest challenges for digital infrastructure.

The technical answer comes with Rubin, NVIDIA’s next-generation AI infrastructure, which the company says is the first to achieve 100% liquid cooling. This means that not only accelerators or CPUs are cooled with liquid, but all chips and network components in the system, within a closed loop. In this architecture, fans disappear and air is no longer the element that keeps the machine stable. Heat is captured much closer to where it’s generated.

The U.S. accused Iran of using the Strait of Hormuz as a pressure tool and called for greater international support to protect global maritime transport
“Washington will do and will continue to do whatever is necessary to protect global maritime transport, but other countries must start stepping up and contribute, whether with material or financial resources, to help share that burden,” said Secretary of State Marco Rubio.

The U.S. accused Iran of using the Strait of Hormuz as a pressure tool and called for greater international support to protect global maritime transport (AP)
U.S. Secretary of State Marco Rubio accused Iran on Sunday night of using the Strait of Hormuz as a pressure tool in the conflict in the Middle East, and called for greater involvement from other countries to protect global maritime transport. He also said that Washington keeps the diplomatic track open if Tehran agrees to a deal and complies with it.

Rubio made the remarks to reporters before traveling to the Philippines to take part in a meeting of foreign ministers of the Association of Southeast Asian Nations (ASEAN). “It is clear that Iran, at least some people in Iran, want to control the strait and use it as an instrument of pressure against the world,” he said.

The head of U.S. diplomacy also called for greater international commitment to ensure the security of one of the world’s main commercial routes. “The United States will do and will continue to do whatever is necessary to protect global maritime transport, but other countries must start stepping up and contribute, whether with material or financial resources, to help share that burden,” he said.

Meanwhile, Bitcoin could surge in the coming days and is trading at around 65,675 USD; that’s a good sign despite the controversy between the United States and Iran.

NVIDIA has its RTX 50 SUPER ready, but one problem has blocked its launch: GDDR7 memory is too expensive. The Jensen Huang company isn’t bringing good news, and the GeForce RTX 50 SUPER graphics cards are becoming a headache for this giant.

A few days ago, it was reported that Nvidia has almost finished its new GeForce RTX 50 SUPER series graphics cards, which are designed to deliver more power to top-of-the-line computers. However, it hasn’t been a smooth road.

Rumors of a possible cancellation due to pricing issues from lack of stock of RAM were joined by a leak that the 5080 SUPER will have a thermal design power of 415 watts. Comparing this figure with the 360 watts consumed by the current standard model, we’re talking about a 15% increase on your electricity bill.

Now a new blow lands for Jensen Huang’s company: manufacturing costs have forced them to halt its release to the market. According to what has been leaked, Nvidia has already sent the first graphics chips to its partners, but it has issued a direct order to freeze everything because the new 3 GB GDDR7 memory is, right now, very expensive.

Inside the new Zcash node aimed at Visa-scale privacy with 50,000 transactions per second
The new client Zakura is the first live piece of a plan to take Zcash from approximately one private transaction per second to payment-network scale.

Who are rebuilding Zcash have a dream: to match the global payment giants Visa and Mastercard by handling tens of thousands of payments per second, while maintaining full verifiability and strong privacy guarantees.

The first part of that plan is Zakura, a new full node software that was released Wednesday in version 1.0.0. It is maintained by Sean Bowe, a founding member of Zcash’s zero-knowledge cryptography, and Dev Ojha, cofounder of Osmosis, who now leads Valar Group. Both teams are funded through private donations of ZEC rather than a company or a foundation.

Our dream is to support payments at a global scale. Mastercard and Visa handle more than 50,000 transactions per second; that’s our floor. With Zcash’s existing cryptography, that volume would require more than 500 MB/s of throughput per node, said a blog post. The current technology stack won’t get us there. The cryptography our teams are developing closes much of that gap.

NVIDIA reclaims its historic partnership with SEGA: its games will debut on RTX Spark
Thirty years after the now-defunct NVIDIA NV1 graphics card brought the first Virtua Fighter to PC, SEGA and NVIDIA cross paths again. The Japanese company has confirmed that several of its games will come to RTX Spark, NVIDIA’s new AI-enabled PC platform.

This move not only strengthens their technological collaboration, but also brings back one of the most curious chapters in both companies’ history. If you’re of a certain age, you’ll know what we’re talking about—and if not, you’re still in time to try these classics on the new platform.

NVIDIA and SEGA reunite
What’s interesting about this announcement is that it’s not just a new collaboration between the two companies. In reality, it closes a circle that began 30 years ago. In 1996, Virtua Fighter was one of the first SEGA games to reach PC thanks to the NVIDIA NV1, a graphics card very different from the ones that eventually dominated the market. That bet didn’t go very well, but it did help NVIDIA and SEGA work together.

Now that story repeats itself, though in a completely different way. RTX Spark will be responsible for bringing several SEGA classics to this new NVIDIA platform, allowing you to enjoy some of the most remembered titles from the 1990s on current hardware.
