Around 594.5 BTC (≈$38M) was reportedly drained from nearly 500 wallets on July 30 after attackers exploited weak seed generation on Coldcard Mk3 devices.
The issue affects seeds generated with firmware versions 4.0.1–5.0.3 (since March 2021). Due to insufficient entropy, attackers were able to reconstruct some private keys offline.
✅ Not affected:
• Coldcard Mk4, Q, and Mk5
• Wallets protected with a BIP-39 passphrase
• Multisig setups
• Dice-roll generated seeds
⚠️ If you generated a seed on a Coldcard Mk3 with the affected firmware and aren't using a passphrase, consider moving your funds to a newly generated wallet as soon as possible.

🇺🇸🏛 U.S. public companies are buying Bitcoin faster than miners can produce it!
American publicly traded companies now hold 1.24 million BTC, accounting for nearly 93% of all corporate Bitcoin reserves worldwide. 🧐
Over the past year alone, they added 510,000 BTC to their treasuries—more than three times the amount of new Bitcoin mined during the same period.

📉 Strategy reports an $8.32B unrealized loss on its Bitcoin holdings in Q2 2026
📝 The company ended the quarter with 843,775 BTC on its balance sheet, compared to an unrealized gain of $14.05B in the same period last year.
Michael Saylor also signaled a more flexible treasury strategy, saying the company may sell BTC when necessary rather than continuously buying regardless of market conditions. 🤔
Despite the headline loss, MSTR shares rose around 5%, suggesting investors welcomed the more disciplined capital management approach instead of aggressive buying through every market decline. 📈
The update marks a notable shift in Strategy's playbook while reinforcing that Bitcoin remains at the core of its corporate treasury.

🤖 Is AI making Bitcoin mining obsolete?
According to Frank Holmes, Chairman of HIVE Digital Technologies, traditional Bitcoin mining is becoming far less profitable than AI computing. 🧐
🧮 He estimates that a typical ASIC miner generates only $0.12–0.14 per hour, while an NVIDIA H100 GPU used for AI workloads can earn around $2 per hour. Even older GPUs may generate about $1.40 per hour—roughly 10x more than crypto mining.
This growing profitability gap is pushing some mining companies to diversify into AI infrastructure, renting GPU computing power instead of relying solely on Bitcoin mining.
As AI demand continues to surge, the competition for energy and data centers may increasingly shift from mining Bitcoin to powering artificial intelligence. 🛠➡️🤖

📉 Bitcoin starts August with weakness—is the seasonal dip beginning?
BTC has already slipped below $63,000 on the first day of August, raising the question: is the next leg down underway?
Historically, U.S. midterm election years have often seen an average Bitcoin correction of around 13.5% from summer highs. From current levels, that would imply a move toward $55K.
Adding to the bearish seasonality, September has traditionally been Bitcoin's weakest month. If history repeats itself, the next two months could offer one of the best accumulation opportunities before the market recovers.
Of course, past performance doesn't guarantee future results—but it's definitely a period worth watching closely. 👀

Coldcard wallet exploit losses climb to $89M! 🙀
🚀 According to Galaxy Research, a third wave of attacks has targeted vulnerable Coldcard Mk3 hardware wallets, with hackers stealing another 208 BTC from around 1,900 addresses.
In total, the exploit has now resulted in the theft of 1,367 BTC (≈$89 million) across 4,585 wallets. Researchers say the vulnerability stems from a 2021 firmware bug that generated seed phrases using predictable software entropy instead of the device's hardware random number generator, allowing attackers to reconstruct private keys offline. 🧐
Galaxy also reports that some of the stolen funds are already being laundered through THORChain and online casinos.
⚠️ If you created a wallet on a Coldcard Mk3 using the affected firmware and are not protected by a BIP-39 passphrase, consider moving your funds immediately.

Michael Saylor said Strategy has never had a "never sell" policy 😁
Strategy still expects to remain a net buyer of BTC over the long term.
Saylor also pointed out that Bitcoin has traded above its 200-week moving average 92% of the time since the indicator was introduced. With BTC currently hovering near that level, many investors see it as a key long-term support zone.
👀 And over the weekend, Saylor added even more fuel to the speculation by hinting at another Bitcoin purchase by Strategy—continuing the company's accumulation strategy despite recent own words.

📈 DEXs continue to gain ground on centralized exchanges
The share of decentralized exchanges (DEXs) in spot crypto trading has climbed to a record 24% of total CEX spot volume—the highest level since tracking began in 2019. 💪
Just a year ago, in 2024, DEXs accounted for less than 10% of the market. Today, they handle nearly one-quarter of all spot trading. 📊
The trend reflects growing demand for self-custody, onchain trading, and permissionless access, while DEX infrastructure continues to improve in speed, liquidity, and user experience.
If this momentum continues, the gap between centralized and decentralized trading could narrow even further in the coming years. 🤔

⛏️ Bitcoin miners are capitulating—but the market is looking beyond mining
Bitcoin's hashrate has been declining for 287 consecutive days, while mining difficulty is down nearly 20% from its peak, marking one of the sharpest miner capitulations in the network's history. 📉
Despite the pressure on mining profitability, shares of public mining companies continue to rise.
Why? Investors are increasingly valuing these companies not just as Bitcoin miners, but as future AI infrastructure providers. With access to power, data centers, and high-performance hardware, many miners are pivoting toward AI and high-performance computing to diversify revenue.
🤖 The market is starting to price in a future where mining companies earn not only from Bitcoin, but also from the growing demand for AI computing.

🎯 BitGo CEO challenges Claude AI to hack a wallet holding 100 BTC
After Anthropic claimed that Claude had, in some tests, acted beyond its sandbox and gained unauthorized access to real systems, BitGo CEO Mike Belshe called for a real-world demonstration.
Belshe argued that either Anthropic's testing environments are poorly isolated—or the company is overstating Claude's capabilities. To put the claims to the test, he publicly funded a wallet with 100 BTC and challenged Claude to steal the funds.
👀 The wallet is public, so the crypto community can watch in real time to see whether anything happens.

📉 Crypto social activity has fallen to multi-year lows
The number of posts about Bitcoin and Ethereum on X is now at one of its lowest levels in years. The last time sentiment and social engagement were this quiet was just before the 2021 bull market. 🤔
Historically, periods of low attention have often coincided with market bottoms, when interest fades before the next major move.
Of course, history doesn't always repeat itself. The bigger question is which crypto projects will survive long enough to benefit from the next bull cycle.
For long-term investors and airdrop hunters alike, this could be the time to focus on quality rather than hype. 👀

Despite today’s announcement with orange dots, Strategy sold 1,638 BTC last week for $104M at an average price of $63,957 🙀
The proceeds will be used to pay dividends on STRC preferred shares and repurchase STRC while it trades below its $100 par value. Until STRC returns to $100, Strategy is unlikely to issue more of these shares, reducing one of its main funding sources for future BTC purchases.
The company still holds 842,138 BTC, acquired at an average cost of $75,419 per coin, plus $4B in cash.
📈 Interestingly, the market shrugged off the news. After the U.S. session opened, Bitcoin rebounded nearly 2%, fully recovering its earlier losses and showing that demand remains resilient despite Strategy's first notable BTC sale.

💀 A $130M hardware wallet exploit... traced with just $2 worth of AI
Losses from the Coldcard Mk3 vulnerability have now climbed to 2,000 BTC (≈$130M).
Dragonfly partner Haseeb Qureshi reported that he was able to identify the root cause of the vulnerability in the Coldcard code using an AI assistant in just 8 minutes, spending only about $2 in inference costs. He later repeated the analysis offline, confirming the bug in around 20 minutes.
The incident highlights how AI is dramatically lowering the barrier for auditing—and potentially exploiting—software vulnerabilities.
🔐 One takeaway remains unchanged: if you generated a seed on an affected Coldcard Mk3 firmware, move your funds immediately. And maybe... paper backups are starting to look cool again. 📝

🐂 Bitcoin sellers may be running out of steam
🔎 The on-chain Seller Exhaustion indicator has dropped to levels previously seen only near major market bottoms—around $3K in 2019, $16K in 2022, and $25K in 2023.
The signal suggests that most panic sellers have already exited, leaving fewer participants willing to sell BTC at current prices.
📈 What the market may need now is a strong positive catalyst. A major event—such as progress on the CLARITY Act or another bullish regulatory development—could tighten supply even further and trigger a sharp move higher if demand picks up.
While no indicator guarantees a reversal, seller exhaustion has historically appeared near important accumulation zones.

🔐 How long would it take to crack your password?
🕵️♀️ Researchers tested password strength using a system equipped with 16 NVIDIA RTX 5090 GPUs, and the results are a good reminder to upgrade weak passwords.
📉 An 8-character password made up of only lowercase letters can be brute-forced in about two weeks.
🛡 An 8-character password using uppercase and lowercase letters, numbers, and special characters could take around 132 years to crack.
The biggest takeaway? Password length matters even more than complexity.
✅ Use passwords that are 12–16+ characters long.
✅ Mix uppercase, lowercase, numbers, and symbols.
✅ Always enable two-factor authentication (2FA).
A few extra characters can make the difference between a password that's cracked in days and one that would take centuries.

Blockchain investigator Specter has identified 28,555 BTC (≈$1.8B) that may be connected to one of the largest alleged cryptocurrency fraud cases ever.
The investigation began after a dormant wallet moved 1,020 BTC following 8 years of inactivity. Tracing the funds led to addresses associated with Zhimin Qian, whose case previously resulted in the UK seizing 61,000 BTC.
Interestingly, the newly identified wallets have remained almost completely inactive since June 2021.
👀 It's still unclear whether these coins are controlled by the original owners, another custodian, or are already under law enforcement surveillance. For now, the massive stash remains one of the biggest dormant Bitcoin mysteries on-chain.

🚨 Coldcard Hack Sparks FTX-Style Bitcoin Panic
🔎 According to CryptoQuant, news of the Coldcard hack triggered a wave of Bitcoin withdrawals as users rushed to move their funds to other wallets.
On July 31, holders with balances of less than 1 BTC transferred 39,600 BTC—almost matching the 39,900 BTC moved during the panic following the FTX collapse in November 2022.
The data highlights how security incidents can quickly shake investor confidence, leading to large-scale self-custody movements even without a broader market crash. While the numbers resemble the FTX exodus, it's still too early to say whether this will have lasting market impact.

The proposed deal could include:
• Shared oversight of shipping through the Strait of Hormuz between Iran and Oman.
• A coordinated plan to clear naval mines from the waterway.
Despite the headlines, markets remain cautious. Similar ceasefire announcements have surfaced multiple times before, so traders are waiting for concrete implementation rather than reacting to promises. Bitcoin showed only a modest gain of around 0.9%, trading near $64.2K, reflecting the market’s muted response. 🤷
