A research report published by Blockworks Research shows that among the 1,972 tokens that first broke through a circulating market value of $50 million between January 2020 and December 2025, only 4.1% outperformed Bitcoin as of June 2026. Among tokens with at least 24 months of historical data, this percentage drops to 1.7%. The median token in the full sample has lost 97% since entering the statistics.The report points out that the token market presents a pyramid structure with a "wider base and thinner top." The number of tokens with a market value exceeding $1 million reached a historical high of 3,648 in December 2024, but the tier with a market value exceeding $250 million has continued to shrink since peaking in November 2021, with only 102 tokens above that threshold as of June 2026, about one-third of the 279 in November 2021. Among the 187 tokens that outperformed Bitcoin during the 2020-21 bull market, 86.1% have since fallen at least 90% from their peak in November 2021, with only OKB continuing to outperform Bitcoin.The report also found that token performance deteriorates more rapidly over time: 86% of tokens issued in 2024 fell below 10% of their initial price within 24 months, while the proportion for tokens from 2020 during the same period was 18%. The median peak price of new tokens after 2023 is only 0.93 times the listing price, meaning it has never exceeded the listing price, while the median peak price for 2020 tokens reached 5.1 times. Exchange tokens are the only significant over-representatives in the long-term outperforming Bitcoin group, with BNB, OKB, GT, LEO, BGB, WBT, MX, and CAKE (PancakeSwap) all outperforming Bitcoin, sharing the common feature of fee revenue being used for regular buybacks and burns. The report's authors state that the crypto market is shifting from a broad token expansion to a pattern driven by a few high-quality assets.

According to monitoring by the head of Galaxy Research, less than 1 BTC was stolen overnight through a victim's report, identifying a new attack where the attacker transferred 12 BTC from 126 addresses, with the attack footprint marked as "footprint O."

According to Jinshi reports, Barclays stated that 85% of the S&P 500 index constituent companies exceeded earnings expectations in the second quarter, far above the long-term average of 76%. Revenue grew by 11.2% year-on-year, and earnings per share surged by 25.1% driven by large tech stocks. Despite the strong performance, Barclays pointed out that both earnings exceeding expectations and falling short triggered negative reactions in stock prices, indicating that investors have digested most of the positive news.

According to Goldman Sachs, it will include Applied Materials (AMAT.O), Delta Air Lines (DAL.N), Microsoft (MSFT.O), and United Parcel Service (UPS.N) in the list of stocks to buy with confidence. It will remove Broadcom (AVGO.O), Dick's Sporting Goods (DKS.N), Johnson & Johnson (JNJ.N), and ServiceNow from that list.

According to Bits Media, Russian law enforcement conducted a series of searches at a cryptocurrency exchange office located in the Federal Eastern Tower of the Moscow City Business Center. The police stated that the searches are related to a theft case involving 144 million rubles, with the funds suspected to have been circulated through related exchanges. They are currently tracking the transactions and investigating whether the office staff are involved.During the investigation, dozens of employees were detained, and a Moscow court has ordered pre-trial detention for eight of the defendants, while the procedural status of the remaining detainees has not been disclosed. The office temporarily ceased operations during the searches.

According to monitoring by Galaxy's research director, a suspected organized Coldcard attack is occurring, with similar transactions still waiting for confirmation in the mempool. Previously confirmed transactions show RBF enabled. During the period from block 960,778 to 960,792, 218 transactions occurred within approximately 2.5 hours, involving 462 victim addresses, 216 new destination addresses, and 388.92748828 BTC; all transactions had no inputs earlier than the Coldcard firmware boundary.The clearing rate per block during this period was 13.8 times, compared to a pre-incident control window of 0.3 times per block, approximately 45 times higher. The transaction topology was 1:1, with each victim address corresponding to a new destination address, and only one destination address received two clearings, with no aggregation addresses appearing. Some funds have been cleared to second-hop addresses.

Galaxy Research Director Alex Thorn stated that the attack incidents surrounding the Coldcard wallet are still evolving, with more small attackers and imitators emerging, targeting the remaining Coldcard recovery phrases.Alex Thorn mentioned that by assisting in confirming the identity of a user whose deposits were involved in the attack, the related funds had already been transferred out before they could be frozen on the Duel platform, and the funds involved do not belong to the three main waves of attacks previously identified by Galaxy Research.Previously, the Bitcoin hardware wallet Coldcard was attacked, and the stolen funds have risen to 1367.05 BTC, worth approximately 8.86 million USD, involving 4585 addresses. Galaxy Research Director Alex Thorn stated that the attacks are still ongoing, and users who have not yet migrated their funds should immediately transfer their assets out of the addresses generated by Coldcard.

Researchers at the Chinese People's Public Security University have developed an AI framework capable of detecting illegal cryptocurrency transactions with an overall accuracy rate close to 90%. The study was published in the Chinese peer-reviewed journal "Journal of Intelligence," and the corresponding author, Dr. Sun Jingchao (specializing in criminal investigation and cybersecurity), noted that the research "provides an accurate, scalable, and interpretable solution for detecting illegal cryptocurrency transactions," and offers "an innovative technical path" for regulatory agencies to combat illegal cryptocurrency transactions and economic crimes.This AI framework utilizes memory modules and large language models, specifically targeting the anonymity and cross-border characteristics of cryptocurrencies to track illegal activities such as money laundering. The release of this research coincides with China's ongoing efforts to intensify the crackdown on financial crimes related to cryptocurrencies. In March of this year, the Supreme People's Procuratorate of China disclosed that by 2025, procuratorial authorities had prosecuted 3,259 individuals for money laundering crimes involving virtual currencies and underground banks.As the trading volume of cryptocurrencies rapidly increases, their anonymity and cross-border characteristics provide a channel for illegal fund flows. This police-developed AI detection tool marks a shift in regulatory technology from passive tracking to proactive intelligent identification.

Galaxy Research Research Director Alex Thorn stated that the attack targeting Coldcard wallet address generation is still ongoing. They are currently continuing to collect victim information and adding new victim addresses and attacker addresses to the investigation database.If users are still using affected Coldcard single-signature addresses, they should immediately migrate their funds. According to current investigation results, all single-signature Coldcard addresses generated after the firmware upgrade in March 2021 may ultimately be emptied by attackers; it is just a matter of time.According to Galaxy Research's analysis, the first three confirmed rounds of attacks exhibit highly programmatic characteristics, with similar attack transaction patterns. A large amount of stolen Bitcoin remains in the attackers' addresses and has not yet been transferred.At the same time, some new opportunistic attackers are emerging, transferring and laundering funds through methods such as stripping the funding chain, cross-chain services (like ThorChain), and overseas betting platforms.Additionally, Alex Thorn mentioned the limitations of AI tools in security investigations. Some large language models in the United States have restricted researchers' ability to track stolen funds, and the team has even had to turn to Chinese open-source AI models to assist in protecting user assets and conducting on-chain tracking.He finds this phenomenon "incredible" and plans to promote discussions on related issues at the government and industry levels. Alex Thorn concluded by stating that a large amount of stolen funds remains stagnant, and the team is continuously tracking relevant addresses, having shared information with relevant U.S. agencies and industry partners. He calls on the Bitcoin community to learn from this incident, strengthen self-custody security education, and raise awareness of wallet complexity.

According to official news, OpenAI has released research results stating that its next-generation AI model Astra has made progress in the fields of mathematics and theoretical computer science, involving areas such as high-dimensional geometry, coding theory, group theory, quantum complexity, post-quantum cryptography, and extremal combinatorial mathematics. The 10 published results include: the high-dimensional sphere packing problem, binary and spherical coding problems, non-sofic group problems, Connes rigidity conjecture, arithmetic circuit complexity problems, quantum parallel repetition problems, nearest vector problems, Ehrhart volume conjecture, multi-color Ramsey number problems, and extremal graph theory conjectures.It is reported that these results were derived using an internal version of the Astra model, with the computational cost of finding solutions amounting to approximately $2000 (calculated based on Sol API prices).Subsequently, human researchers used the same model to assist in compiling the results into a paper and generated verifiable proof certificates through the Lean formal proof system.

Samsung Electronics and SK Hynix are accelerating their layout of HBM and next-generation storage technologies to maintain their leading advantage. Samsung Electronics stated that its R&D investment reached a record 16 trillion won (approximately 11.6 billion USD) in the second quarter and plans to expand its layout of high-end storage products such as HBM4, HBM4E, and DDR5.SK Hynix is developing next-generation technologies such as HBM5, hybrid bonding, and iHBM, with capital expenditures expected to reach 40 trillion won (approximately 32.6 billion USD) this year.

Galaxy Research Research Director Alex Thorn tweeted that among a Coldcard attack victim holding nearly 30 BTC, 17 BTC were split and converted to ETH via THORChain, and then deposited into the offshore betting platform Duel.com.Upon tracking, this portion of funds corresponds to approximately 229.72 ETH (worth about $445,000). The victim and the research team have emailed all known addresses of Duel.com, providing all transaction and deposit information and requesting to freeze the funds, but the response stated that the victim should have the police contact them, even though the platform's anti-money laundering policy claims it implements KYC and complies with relevant laws.Thorn stated that this response is unacceptable, and most of the Western regions have passed midnight, meaning the police report cannot be advanced until at least Monday; he believes that if the platform refuses to freeze the funds after receiving notification that they originated from an ongoing cyber attack, it constitutes complicity in theft.Since Duel.com's X account has been banned, Thorn turned to @ several individuals associated with the platform, urging them to push the platform to take the correct actions, and stated that if the funds are not frozen, the platform will face significant legal action.

According to Jinshi reports, Iain Simmons, an analyst at the Oxford Economic Institute, stated that the inflation rate in the Eurozone remains above target levels and faces significant risks in the future. Due to the escalating situation in the Middle East leading to high energy prices, the overall inflation rate rose by 0.1 percentage points in July, reaching 2.9%. He pointed out that since the breakdown of the Iran ceasefire agreement, the risk of broader inflationary impacts has significantly increased, which strengthens the case for an interest rate hike in September.Nevertheless, the inflation data shows a relatively mild response to the escalating situation in the Middle East, and the second round of wage effects later this year may be limited.

Gate Research Institute released a thematic report on Robinhood Chain. The report points out that Robinhood Chain aims for tokenized stocks, ETFs, and other RWAs as its long-term direction, but in the early stages of the mainnet launch, growth is primarily driven by Meme, Launchpad, and Uniswap trading, forming a structure where RWA serves as a long-term asset endpoint and Meme acts as a short-term liquidity engine. The high turnover of popular tokens such as CASHCAT and PONS reflects that the market is pricing around the Robinhood brand, on-chain retail trading culture, and launch platform traffic.The report also believes that Gate DEX's comprehensive access to Robinhood Chain supplements the ecosystem's external multi-chain entry points. In the early development stage of Robinhood Chain, AMMs like Uniswap mainly undertake price discovery and liquidity formation for on-chain assets, while Gate DEX complements the inflow paths for external funds and users through asset discovery, trading entry, and cross-chain capabilities. Gate Alpha supports the discovery and trading of ecosystem assets and multiple launch platforms, while Gate Wallet, Swap, professional trading, and market modules simultaneously cover this network; relying on Across and LayerZero, users can conduct cross-chain exchanges between BSC, Ethereum, Base, and Robinhood Chain. Overall, Gate DEX mainly undertakes asset distribution and fund routing functions within the ecosystem, helping Robinhood Chain connect with a broader multi-chain user base by lowering the operational threshold for users to discover assets, enter cross-chain, and participate in trading.

According to Jinshi reports, the head of application research at OpenAI stated that GPT-5.6 Luna should have more applications, considering the rapid progress of the model, its cost is ridiculously low, and its speed is also very fast.

According to CNBC, Situational Awareness, an AI-themed hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, sold its entire publicly traded stock portfolio in a single transaction to another hedge fund before the market opened on Thursday, with the buyer undisclosed. The fund also sold a significant stake in Anthropic. The fund manages approximately $20 billion to $24 billion, and as of the end of June, it had a net return of 439%, making it one of the best-performing hedge funds this year.According to insiders, this liquidation was due to significant losses in recent weeks. The fund had long positions in AI infrastructure and semiconductor stocks such as SK Hynix, Nvidia, Micron, and CoreWeave, most of which fell over 35% this month, while its short positions in software stocks like Adobe also experienced significant reverse volatility. According to its 13F filing submitted on March 31, about 62% of its $13.68 billion holdings were bearish options betting on declines in semiconductor and tech stocks. It is reported that major brokers such as Bank of America, Goldman Sachs, and JPMorgan are assisting the fund in meeting margin calls or orderly reducing positions, and Aschenbrenner has sought new capital from existing investors and lenders.
