When investors entered their Bitcoin keys into physical wallets, they thought they were safe. Until a hacker guessed them.

A flaw in the ColdCard wallet’s random number generator has caused chaos
The attackers have already stolen 1,367 bitcoins—about $89 million—without physical or remote access to those devices.

Anyone who has ever invested in cryptocurrencies knows this well: physical wallets (“cold wallets”) were the ideal way to protect them from potential thefts. Those wallets always promised the same thing: that the keys that allow you to move the money never leave the device. That was a lie.

Catastrophe. On July 31, hundreds of ColdCard wallet owners watched as, in just 40 minutes, their money disappeared from their devices. The attacker didn’t need physical access to the devices, nor to infect them or connect to them. They only had to do something that should have been impossible: guess the keys to steal that money. The theft has affected 1,367 bitcoins—about $89 million at current prices—which were taken from 4,585 addresses belonging to different wallets. It’s a “smaller” theft compared to others in the past, but what matters is how it was carried out.

The safe door was still locked. The attack didn’t even break the wallets’ implicit isolation, nor did it extract keys stored on them. The flaw was even more serious: it occurred at the moment the device created those keys. A Bitcoin wallet first generates a seed—a sequence of random data. Private keys and addresses are derived from it. If that seed is truly unpredictable, trying all possibilities becomes unfeasible, even for the best supercomputers on the planet. The problem is that if the seed isn’t, it doesn’t matter whether the safe (the wallet) is completely isolated and closed.

SpaceX faces decisive days: it presents its quarterly accounts and another 20% of shares could be released to the market
The results presentation on August 4 opens the window to sell blocked shares
The market braces for a possible flood of 6.4 billion shares
Bearish pressure on SpaceX surges to $25 billion, and short bets have already reached a third of its float.

June 12, 2026 will go down in the annals of U.S. stock-market history as the day space travel, orbital data centers, and intergalactic civilizations took their leap onto the trading floor. SpaceX debuted on Nasdaq under the market’s scrutiny, amid the fervor of the constellation and an unprecedented wave of FOMO (fear of missing out). A swirl of expectations that led the stock to add a 50% rally in its first three days as a listed company. A mere anomaly. Since then, the shares have collapsed, falling 20% below their offering price ($135), which conditioned its success on a potential market—the one for space—valued at $30 trillion by Elon Musk himself. In the long run, the prophecy has clashed with today’s fundamentals, which barely back the $1.8 trillion valuation at which it debuted on Wall Street and, more than a month later, now hovers around the $1.4 trillion mark.

With this, at least a complex situation, the new flagship firm of the South African tycoon finds itself immersed in what is being touted as its first turning point in the equities market: the release of its results for the months of April through June this August 4. It has not earned the backing of market consensus, whose analysis projects red numbers for the second quarter in line with what the corporation reported in previous fiscal years.

Iran War, latest live updates | Trump says peace negotiations with Iran will resume today

Follow live the latest news on the conflict in the Middle East and updates on the negotiations for the peace agreement.

US President Donald Trump said he had stopped "the biggest attack since World War II" on Iran at the request of several countries in the region, including Tehran. The pause in offensives has allowed both countries to restart negotiations for a peace agreement. For its part, the Islamic Republic is negotiating the future of Hormuz with Oman.

US breaks 28-year rule to save the yen: Bitcoin reacts Bitcoin briefly lost the $63,000 level on Friday, and the reason is 9,600 kilometers away. The United States bought Japanese yen for the first time in 28 years.

Washington almost never does this. The goal was to support a currency that was weakening. It also affected one of the world’s biggest financial operations. Crypto is at the end of that chain.

What really happened
The yen has been falling for years. Last week it reached 163.99 per dollar, and it continued to drop this weekend. That’s close to a 40-year low.

Japan was the first to act, on Thursday. It sold dollars and bought yen. This is called intervention. A government buys its own currency to make the price rise.

Washington joined on Friday. The New York Fed sold euros and bought yen for the Treasury Department. It used Goldman Sachs and Morgan Stanley, according to the Financial Times.

Why Jensen Huang says this is the best time in history to start a business
Nvidia CEO believes continuous learning is key for today’s entrepreneurs Jensen Huang.

The executive director and cofounder of Nvidia argues that this is the best time in history to start a business.

In a recent conversation with Garry Tan, CEO of Y Combinator, during Startup School 2026, Huang admitted he was jealous” of the opportunities opening up for new founders thanks to the momentum of artificial intelligence and the technologies his own company has helped develop.

A landscape shaped by technological transformation
Nvidia’s path began in 1993, when Jensen Huang, Chris Malachowsky, and Curtis Priem sketched out in a restaurant the vision for what—more than three decades later—would become one of the most valuable companies in the world, with a market capitalization of nearly $4.7 trillion.

The company’s expansion has been driven by global demand for artificial-intelligence chips, a phenomenon Huang believes offers unprecedented possibilities for those who want to found their own businesses.

“This is absolutely the best time to start a company,” Huang said during his meeting at Y Combinator. His enthusiasm, far from being based on the ease of success, stems from the conviction that technology provides unprecedented tools for those willing to try.

Learning on the go is key for entrepreneurs
Huang also emphasized that the main obstacle for entrepreneurs is often the tendency to overthink challenges before taking action. “How difficult can it be?” he asked.

I think something big is coming for BITCOIN based on my research data; experts predict that Bitcoin by the end of this year 2026 could reach 140,000 USD up to 150,345 USD. I'm not sure whether that's true or not—it could be certain or uncertain—but what I can tell you is that something big could happen with the price of Bitcoin; it could jump sharply at any moment.

The ColdCard hack expands: now there are 2,600 stolen wallets
Galaxy Research detected a second wave of the attack and raised the stolen amount to 1,158.81 bitcoin.

The funds remain unmoved in 7 directions controlled by the attackers.
Specialists warn that wallets Mk4, Mk5, and Q would also be targeted.

Galaxy Research, the market research division of the digital asset investment firm, identified on August 1, 2026 a second wave of attacks linked to the vulnerability in Coldcard hardware wallets and significantly increased the scope of the incident. According to the firm, it has already tracked 1,158.81 bitcoin (BTC) stolen from 2,673 wallets, whose funds remain unspent in seven addresses controlled by the attackers.

The update represents a major increase compared to the analysis published a day earlier, when the investigation had identified 1,196 compromised wallets and 1,082 BTC stolen. The new report attributes these additional emptyings to the same attacker who carried out the first wave.

Bitcoin and how tokenized perpetual contracts compete with their markets on Hyperliquid and Binance Tokenized asset markets are entering a new phase with a sharp increase in trading volumes. Perpetual contracts backed by equities and commodities now rival Bitcoin-related products on Hyperliquid and Binance. This evolution illustrates a gradual diversification of exchanges on specialized platforms. The latest data also shows that this dynamic continues, driven by growing demand for trading instruments accessible around the clock.

Tokenized asset perpetual contracts generated $61.7 billion in volume over one week.
Tokenized equities account for nearly 58% of trades, ahead of commodities.
Hyperliquid records an RWA volume higher than all its other perpetual contract categories combined.
Early weekly figures show that RWA contracts now exceed Bitcoin perpetual contract volume.

Perpetual contracts on tokenized assets rival Bitcoin Perpetual contracts backed by real assets (RWA) now record a volume close to that of Bitcoin contracts on Hyperliquid and Binance. Talos data, shared by Cointelegraph, shows that these products are gaining ground rapidly, illustrating an evolution in activity on the two main specialized platforms.

A drifting SpaceX rocket speeds toward the Moon
It is expected to crash into the surface of the natural satellite on Wednesday.

It is estimated that the rocket’s impact will generate a crater nearly 27 meters in diameter and 5 meters deep on the lunar surface.

CAPE CANAVERAL, Florida. A drifting SpaceX rocket is headed for the Moon after launching two lunar modules more than a year ago.

The rocket’s upper stage will accidentally impact the Moon on Wednesday, creating a crater and kicking up a cloud of dust and debris that scientists and astronomers are eager to observe.

Space tracking expert Bill Gray predicts an impact at 8,700 km/h (seven times the speed of sound) near the Einstein crater, in the western margin illuminated by the Sun. Since the event will unfold in the early morning hours, eastern areas of the United States and Canada, as well as much of South America, will have the best views.

Musk’s fortune falls back to USD 684 billion due to SpaceX’s decline
Elon Musk’s wealth fell from USD 1.33 trillion to USD 684 billion after SpaceX’s IPO and Tesla’s pullback. SpaceX shares dropped 46%, and Tesla has accumulated a 36% decline since December, according to Bloomberg’s Billionaires Index.

SpaceX successfully carried out a launch on Friday afternoon from its Starbase facilities in southern Texas and placed its Starship rocket into orbit. However, the mission’s success did not prevent Elon Musk’s fortune from falling back to Earth.

The world’s first trillionaire is now poorer than before SpaceX’s IPO last month, according to Bloomberg’s Billionaires Index.

Tokenized gold: how the crypto technology works that allows you to buy a gram of precious metal without having it in your hand
A platform lets retail investors buy a gram of the gold metal with physical backing, an international price, and the security of blockchain technology.

Gold is the most traditional investment and, for many, the most conservative during times of crisis. The various ways to buy it now bring blockchain technology to Argentina—the same used by cryptocurrencies. Tokenized gold means you can invest in the precious metal represented digitally but backed 100% by physical gold.

The platform that will offer this service for the first time in the Argentine market will bring together, with an international price, the custody, trading, tokenization, and liquidity of gold. It was created by Prosegur Crypto, the digital assets unit of the well-known cash logistics company.

Russia issued an international arrest warrant against the creator of Telegram
Pavel Durov, who has lived outside the country for years, is accused of complicity in terrorism for failing to remove content linked to acts of sabotage against the country.

This Wednesday, Russia announced that it is seeking the detention of Telegram founder Pavel Durov based on accusations of complicity in terrorism, claiming that he allowed the platform to be used for recruitment by Ukraine’s security services.

Born in Russia, Durov is a serial tech entrepreneur who has lived outside the country for years and holds French and United Arab Emirates passports. He has frequently clashed with Russian authorities as Moscow tightened its control over the internet.

His Telegram messaging app is one of the country’s main communication platforms, and authorities have repeatedly tried to block access or curb its success, in an attempt to pressure Durov into handing over user data or to push Russians to use an unencrypted state alternative.

The Federal Security Service (FSB) said it had launched an international search process against Durov, who is also Telegram’s chief executive officer. An international search notice was issued... for the head of Telegram’s administration, P. Durov, he said in a statement. It was not clear what kind of search notice Russia issued, nor whether other countries or law enforcement agencies would accept or comply with it.

War on social media
Moscow often accuses its political opponents of supporting terrorism or extremism, including those who left the country. The FSB claimed that Telegram had been used as a recruitment platform for Ukrainian security services seeking to coerce Russian citizens into carrying out sabotage acts, and that Durov had not removed information prohibited by Russia and Ukraine.

Jensen Huang anticipates the end of programming and reveals what to learn to work with AI
The founder and CEO of NVIDIA said that writing code will become increasingly automated. At Startup School 2026, he explained why systems thinking, the hard sciences, the ability to learn, and resilience will be the decisive skills of the new economy.

Writing code will no longer occupy the central place it has held for the past few decades in the tech industry. For Jensen Huang, founder and CEO of NVIDIA, artificial intelligence will automate much of that work and force professionals, students, and entrepreneurs to develop a different set of capabilities.

In the case of software, most of it will be done by agents. That’s why you’ll need to be much better at thinking about systems in an abstract way, Huang said during a conversation with Garry Tan, CEO of Y Combinator, at Startup School 2026, held at the Chase Center in San Francisco.

SpaceX shares images of the successful Starship splashdown in the Indian Ocean Miami (U.S.) (EFE).- SpaceX published this Tuesday several images of the thirteenth test flight of the Starship spacecraft, which successfully splashed down in the Indian Ocean last week, days after the launch was postponed due to a malfunction during engine ignition and bad weather.

Elon Musk’s company shared, on the social network X, some photographs and videos of the moment of the splashdown, which took place almost an hour and a half after the Starship lifted off from Texas last Friday.

In the shared footage, you can see how the powerful rocket descends vertically and in a controlled manner toward the surface of the sea, landing on it before tipping over onto its side in the water and remaining afloat.

SpaceX clarified that the spacecraft is still in the Indian Ocean, while the recovery team is collecting images of the rocket.

The two delays of Starship
In addition to the thirteenth test launch of the powerful rocket, it was also the second for the Super Heavy booster, which constitutes the first of the vehicle’s two stages, and the first in which the Starship was equipped with twenty next-generation Starlink V3 satellites.

Aside from fine-tuning the performance of the third version of Starship and the booster, the test also placed the V3 satellites into orbit.

Nvidia is willing to guarantee $250 billion so that OpenAI can have its own data center, according to the WSJ. The deal, which is expected to be the largest in this sector to date, will be the first step for OpenAI to have its own data center
According to the WSJ, Nvidia would guarantee $250 billion as part of a deal of up to $500 billion, even though OpenAI is not the only interested party.

Nvidia is considering becoming the main financial engine behind one of the biggest AI infrastructure projects so far. As The Wall Street Journal has reported, Jensen Huang’s company is negotiating to offer a guarantee of around $250 billion so that OpenAI can lease a massive data-center campus in Ohio, in the United States. All of this, even though the agreement hasn’t been finalized yet.

What exactly is the deal about. Nvidia’s guarantee would not be direct money for OpenAI, but a financial backstop. According to the outlet, it would be used to allow the people behind ChatGPT to lease a 10-gigawatt project being built in southern Ohio by SoftBank’s energy subsidiary, SB Energy.

With Nvidia’s backing, the project could secure financing through debt on better terms, something particularly relevant because OpenAI, being a private company that still hasn’t reached profitability, does not have a credit rating high enough to invest in this type of project on its own.

Bitcoin slips below USD 64,000, but whales keep buying
The U.S. Senate’s pause of the Clarity Law stalls the rise in bitcoin’s price.

On-chain data suggests a BTC accumulation pattern by large investors.
Technical analyst Nicholas Kitonyi says bitcoin has formed a double-bottom pattern.

Bitcoin (BTC) has lost the USD 64,000 level. As of the time of this publication, on the morning of Tuesday, July 28, 2026, the digital coin is trading at approximately USD 63,460, which is nearly 50% below its all-time high reached last October.

At first glance, the chart shows weakness. But the on-chain data tells a different story than what the price reflects.

Analysts project Bitcoin at $200,000 if the CLARITY Act is approved, but 7 obstacles still remain Some analysts say Bitcoin (BTC) could reach $200,000 if the CLARITY Act becomes law. That’s a big if

Right now, seven obstacles stand in the way of the project and a Senate vote.

Why does $200,000 depend on a single law?
Let’s think about the figure. Describe a scenario, not a guaranteed forecast. The FM Intelligence research team sees Bitcoin between $135,000 and $200,000 in the coming year.

This gives a one-in-four chance of that outcome, and only if the law is passed before the November elections. Its main scenario is much lower, between $95,000 and $130,000, according to its published scenarios.

Now let’s look at the difference. Bitcoin is trading at $64,671, up 0.48% in a day, with a market value of $1.29 trillion.
