According to CoinDesk, the UK House of Lords Financial Services Regulatory Committee has called on the Bank of England to reconsider the proposed limits on stablecoin holdings in its latest report. The committee suggested that rather than imposing a holding cap in advance, it would be better to monitor market growth and only implement restrictions when financial stability risks clearly necessitate it. The Bank of England had previously proposed a holding limit of £20,000 for individuals and £10 million for businesses for each stablecoin. The report also questioned the rules on reserve assets, stating that this could have a significant impact on the commercial viability of UK stablecoin issuers. The Deputy Governor of the Bank of England acknowledged last month that the proposed holding limits and reserve requirements were "too conservative" and stated that they are exploring other ways to manage the risks associated with stablecoins.

According to data compiled by institutions, Alphabet (GOOG.O) has initiated an $80 billion equity financing to raise funds for artificial intelligence infrastructure construction, which is expected to become the largest equity capital market transaction in history.The stocks in this joint issuance (including common stock, capital stock, and similar equity mandatory convertible preferred stock) were priced later on Tuesday. Its scale will exceed the approximately $70 billion issuance of common and preferred stock by Petrobras in 2010.The largest single transaction in this deal for Google's parent company—a $40 billion "at-the-market" issuance plan—is expected to launch in the third quarter. Such issuances allow the company to sell shares to the market from time to time without announcement, but it must regularly disclose the amount raised in regulatory filings.

Binance Research stated that the recent weakening of the cryptocurrency market may not be due to the cryptocurrency assets themselves, but rather due to the high concentration of funds in the U.S. stock market. It pointed out that the CBOE Discrete Index rose to 42, the third highest in history, reflecting the concentration of funds within the S&P 500 index towards a few popular themes, which has marginalized Bitcoin.

According to Bloomberg, the White House is reviewing early proposals from the U.S. SEC and CFTC regarding the re-examination of swaps and security swap reporting requirements, which are currently in the pre-rule stage. The two regulatory agencies plan to solicit public opinions before formally drafting regulatory details. The current reporting rules for swaps and security swaps in the U.S. are not unified, and some existing compliance exemption policies will expire in 2029.The International Swaps and Derivatives Association and the Securities Industry and Financial Markets Association jointly sent a letter last month urging regulators to unify the data reporting standards for the two types of products, while ICE Trade Vault LLC made a similar request. The CFTC stated that this work is being carried out jointly by the two agencies, and the SEC chairman has arranged for personnel to establish a unified reporting system during the industry conference in March. The new regulations will require two rounds of agency voting and public consultation before implementation.

CoinShares' latest weekly report shows that global digital asset investment products recorded a net outflow of $1.67 billion last week, marking the third consecutive week of capital outflow and the second largest single-week outflow since 2026, second only to the week of January 23. The cumulative net outflow over the past three weeks has expanded to $4.21 billion, indicating that the risk aversion triggered by the situation in the Middle East has overshadowed the positive impact of the regulatory progress of the U.S. CLARITY Act.Bitcoin investment products experienced a net outflow of $1.438 billion in a single week, setting a record for the largest weekly outflow this year; Ethereum investment products saw a net outflow of $257 million. Due to the continued withdrawal of funds, the global assets under management (AuM) decreased from $148 billion the previous week to $141 billion, the lowest level since early April this year. The U.S. market contributed a net outflow of $1.63 billion, making it the main source of this round of capital withdrawal.At the same time, market risk appetite has significantly declined, with the number of altcoins receiving net inflows dropping from 11 three weeks ago to the current 5. However, XRP, Hyperliquid (HYPE), and NEAR still recorded net inflows of $20.3 million, $10.8 million, and $7.6 million, respectively.

The blockchain security agency PeckShield has issued an alert stating that Gnosis Pay is currently undergoing a security attack. Meanwhile, Gnosis co-founder Martin Köppelmann has publicly urged users to immediately withdraw their GNO and EURe assets to mitigate potential risks.Market analysis indicates that Gnosis Pay, as an important infrastructure connecting payment scenarios with on-chain assets, may face short-term selling pressure on Gnosis GNO and the euro stablecoin EURe if it is confirmed that funds have been stolen or protocol vulnerabilities exploited, further affecting market sentiment for Gnosis ecosystem-related projects.Currently, the official has not disclosed the scale of the attack, the amount of losses, or specific technical details, and the situation is still developing. Users holding related assets or using Gnosis Pay services should closely monitor official follow-up announcements and assess their risk exposure in a timely manner.

A white hat hacker using the alias "0xflorent" stated on X on Sunday that he has helped recover approximately 1,003 ETH (worth about $2 million) from a faulty smart contract of the Hong Coin (HONG) token sale in 2016, involving 48 investors.Hong Coin was originally designed as a community-operated decentralized venture capital fund, with the token sale starting on August 29, 2016, and ending on October 28 of the same year, but it failed to launch due to not reaching its funding goal. The contract was supposed to automatically refund investors, but a vulnerability in the refund function caused the funds to be locked for nearly a decade.0xflorent collaborated with the HONG creator to exploit an administrator function with an integer overflow vulnerability, resetting the token holders' balances and triggering the refund mechanism through specific inputs, successfully extracting the locked funds. According to Etherscan data, one investor has already received a refund of 96 ETH (approximately $192,500). Previously, on May 24, 0xflorent also recovered 19.33 ETH from another failed token sale project from 2018.

According to The Block, a developer using the pseudonym Florent helped rescue approximately 1003 ETH (worth about $2 million) that had been trapped in the 2016 HongCoin ICO contract for nine years through white hat hacking techniques. The ICO was supposed to automatically refund due to not meeting the funding target, but a coding error caused the funds to be locked. The contract used an old version of the Solidity language, lacking overflow protection mechanisms.Florent discovered that by calling the team's admin function and inputting a specific value, he could reset the holder's balance to 1, thereby releasing the ETH through a refund check. This admin function was restricted to HongCoin's multi-signature address. Florent contacted the team and, after verifying the process on the test network, the team signed the unlock transaction themselves. The entire process took about a week, during which the team signed 41 transactions covering approximately 1000 ETH. So far, two investors have claimed 96.5 ETH and voluntarily paid Florent a white hat reward. Florent stated that his motivation was curiosity and understanding how the old contract worked.

According to Marketscreener, Swedish Economic Crime Authority prosecutor Jonas Myrdal stated that the early leak of news on social platform X regarding Sivers Semiconductors (SIVE) considering a dual listing in the U.S., which was officially confirmed by the company about 48 hours later, is not a coincidence and is highly likely to involve information leakage.Jonas Myrdal pointed out that the relevant information was published and continuously promoted on the X platform by an anonymous account with about 200,000 followers before the official disclosure, which subsequently led to a significant increase in the company's stock price within a short period. This pattern of behavior is similar to a previous case involving "pump-and-dump" manipulation, in which three individuals were convicted of serious market manipulation. He further suggested that the Nasdaq exchange should investigate this incident and assess whether there are violations of the EU Market Abuse Regulation (MAR). Currently, the source of the information leak is still under investigation.Previously, the "new stock god" Serenity posted on the X platform, seemingly "calling" Sivers, and expressed an optimistic outlook after further reviewing the latest earnings call content of Sivers Semiconductors. The company's management stated that "viewing ecological partners as competitors is not the correct mindset in a super cycle where demand far exceeds supply," reflecting the current strong demand in the photonics industry. Additionally, the photonics business pipeline has rapidly grown over the past five months, driving an overall revenue pipeline increase of 77%.

According to Cointelegraph, the U.S. spot Bitcoin ETF has seen a net outflow of funds for 9 consecutive trading days, totaling approximately $2.84 billion, setting the longest consecutive decline record since the product's launch in 2024, and surpassing the consecutive outflow record from February 8, 2025. Among them, BlackRock's IBIT has become a major source of outflows.Analysis indicates that this round of capital outflow reflects a significant cooling of institutional demand for Bitcoin ETF exposure, while the market shows a trend of differentiation: ETFs related to Hyperliquid and some XRP spot ETFs still recorded inflows, while Ethereum spot ETFs have faced outflows for 13 consecutive days, with a total outflow of approximately $694 million, indicating that capital in crypto asset ETFs is being reallocated.

Hyperliquid's lobbying organization, Hyperliquid Policy Center, issued a statement welcoming the U.S. Commodity Futures Trading Commission (CFTC)'s latest regulatory initiatives, including the approval of the first listed perpetual contract in the U.S., the release of a policy statement on the listing of perpetual derivatives, related interpretive guidance, and a no-action relief letter, as well as staff consultation documents regarding 24/7 trading, clearing, and settlement.The Hyperliquid Policy Center stated that these initiatives represent the first time in a long while that regulators have explicitly acknowledged the legitimacy and importance of perpetual contracts in price discovery and risk management. It pointed out that past regulatory uncertainty has led to related markets and liquidity flowing overseas, weakening the U.S.'s competitiveness in the global derivatives market.The Hyperliquid Policy Center also expressed its eagerness to work closely with the CFTC to promote the establishment of a regulatory framework that applies not only to centralized intermediaries but also to on-chain protocols. Currently, most perpetual contract trading activities actually occur in on-chain markets.

According to Gate market data, the S&P 500 technology sector has reached a historic high, with a current increase of 1.7%.

Ethereum co-founder Vitalik Buterin recommended the Interfold project, stating, "More people should learn about Interfold, which is a general implementation of the MACI (Minimal Anti-Collusion Infrastructure) concept that I have been advocating for nearly a decade. This project is essentially a privacy protocol optimized for scenarios such as voting and secret auctions, allowing more people to pay attention to and understand this technological advancement."Vitalik also mentioned that the core mechanisms of Interfold include generating threshold encryption keys, users submitting votes on-chain with ZKP qualifications, and performing arbitrary computations followed by threshold decryption in fully homomorphic encryption (FHE), which can achieve unconditional voter anonymity, Ethereum-level censorship resistance, and ZK over FHE ensuring result correctness, among other strong security guarantees. The current main limitation is the high cost of complex computations (such as multiplication), with only addition-based voting being mature. Optimizations such as slashing-based approaches are being advanced, with the long-term goal of achieving obfuscation techniques to eliminate M-of-N committee dependency.

The cryptocurrency market saw a significant decline on Thursday morning, with Bitcoin dropping below $73,000. This round of decline was accompanied by the largest single-day net outflow from the U.S. spot Bitcoin ETF since late January. Nick Ruck, director of LVRG Research, stated that this sharp drop reflects a risk-averse sentiment as profit-taking occurs after recent highs, and is also influenced by rising U.S. Treasury yields and macro caution stemming from geopolitical news.Analysts added that the market decline is primarily due to funds rotating into traditional financial stocks, and once key price levels are breached, a large amount of derivatives liquidation further depressed prices. Data shows that the U.S. spot Bitcoin ETF recorded a total net outflow of $733.4 million on Wednesday, marking the largest single-day outflow since January 29. Among them, BlackRock's IBIT saw a net outflow of $527.8 million, setting a record for the largest single-day outflow since the fund's inception. Additionally, other ETFs like Grayscale's GBTC also experienced negative outflows. Only Morgan Stanley's MSBT recorded a net inflow of $4.3 million.Analysts believe that the outflow of funds is due to basis trade liquidations and institutional de-risking operations, while IBIT's record outflow was influenced by large trades the previous day. Peter Chung, head of research at Presto Research, pointed out that Bitcoin has exhibited a "unique trading pattern" since mid-May, continuing to decline over the past two weeks and underperforming risk assets like the S&P 500 and Nasdaq, primarily driven by outflows from the spot Bitcoin ETF.Analysts are closely monitoring ETF fund flow trends and Bitcoin's support level around $70,000, warning that ongoing fund outflows may indicate that institutions are further adjusting their cryptocurrency asset allocations. On a macro level, Asian stock markets opened lower on Thursday, with the Hong Kong Hang Seng Index and Japan's Nikkei 225 both declining, due to renewed strikes by the U.S. against Iran amid a fragile ceasefire agreement.
