According to the monitoring by the head of Galaxy Research, it has communicated with over 190 victims of Coldcard vulnerability attacks and has asked victims who have not yet contacted them to reach out via private message so that they can provide tracking information and assist in reporting losses to the relevant authorities.Since August 6, no new attack incidents have been confirmed, but this does not mean that new attacks will not occur, and vigilance is required.

Grayscale Research Director Zach Pandl stated that the two major blockchain networks, Ethereum (ETH) and Solana (SOL), are considering adjusting their token economic models to enhance asset scarcity by reducing future token supply growth through lowering annual inflation rates. As important native assets supporting stablecoins and tokenized asset ecosystems, the prices of ETH and SOL are primarily determined by supply and demand dynamics. If the relevant code upgrade proposals are approved, under unchanged conditions, lower supply growth may provide support for token prices.According to Grayscale's analysis, if the relevant adjustments are implemented, the supply inflation rates of BTC, ETH, and SOL will continue to decline over the next five years. By the end of 2031, the annual inflation rates for Bitcoin and Ethereum are expected to be around 0.4%, and Solana around 1.1%, which is lower than gold's annual supply growth rate of about 1.8% and the U.S. CPI inflation level of about 3.3%. Currently, these token economic adjustments are still in the community discussion phase. Among them, the Solana-related proposal has gained broader support and has a higher likelihood of implementation; the Ethereum proposal still requires further discussion.If the adjustments are implemented, staking users may face reduced token rewards, as part of the staking income comes from the issuance of new tokens. However, due to the decline in the growth rate of circulating supply, the scarcity value of the tokens may increase, potentially providing price support. For ETH and SOL holders who do not participate in staking, they may benefit directly; the final returns for stakers will depend on the balance between the decrease in rewards and the increase in prices. Zach Pandl concluded that ETH and SOL are becoming important digital commodities supporting stablecoins and the tokenization of real assets, and the economic model adjustments aimed at reducing inflation may further strengthen their scarcity attributes.

According to official news, Gate will upgrade the Gate Card points reward program on August 14, 2026. After the upgrade, the assets that can be redeemed with Gate Card points will expand from primarily supporting USDT and GT to include USDT, GT, BTC, ETH, GUSD, as well as tokenized stock assets such as NVDAG, AAPLG, GOOGLG, SPCXG, TSLAG, MUG, SNDKG, and SKHYG, corresponding to Nvidia, Apple, Google, SpaceX, Tesla, Micron Technology, SanDisk, and SK Hynix. The newly added tokenized stock assets cover several popular fields such as AI, semiconductors, and consumer technology. After earning points through eligible daily spending, users can redeem mainstream crypto assets like BTC and ETH according to their preferences, or they can redeem corresponding tokenized stock assets like Nvidia, Apple, Tesla, and SpaceX. In addition, Gate Card points will also support the redemption of gold-backed stablecoins (XAUT), effectively enriching users' options for point redemption.The redemption ratio for Gate Card points remains at 100 points = 1 USDT equivalent asset, and points are permanently valid, with other core rules unchanged. Users can still earn cashback points through eligible Gate Card spending, with the cashback ratio continuing to be calculated based on the user's T0--T5 / VIP level. This upgrade will not affect the existing point acquisition mechanism but will provide users with more asset choices at the redemption end, expanding the application scenarios for Gate Card points. By upgrading the points reward program, Gate Card will further connect payment consumption with asset accumulation, offering users richer rights options and a more flexible asset management experience.

According to monitoring by Bitcoin News, new research published by @PraveenPerera shows that Coldcard attackers seem to first identify addresses with vulnerabilities, then sort them by the amount of Bitcoin held, starting to transfer in batches from the addresses with the highest holdings. The transfer software used was relatively crude.One address had 225 spendable UTXOs, and the attackers extracted exactly the latest 200, leaving the earliest 25, which included a UTXO worth 0.16 BTC. This aligns perfectly with the limitation of a blockchain API investigated by researchers, which defaults to returning 200 records, indicating that the attackers may have failed to load the next page of data. The software even spent a UTXO of 294 satoshis, reportedly increasing the transaction fee by about 2040 satoshis, with the spent amount significantly higher than the value of the UTXO itself.The authors of the study believe that the builders of this tool may have a better understanding of the account balance system than of the Bitcoin UTXO model. Although the attackers seem to have obtained the complete seed of the victims, at least 75 BTC still remain in other addresses derived from the same seed. The biggest suspicion currently is that among the 153 stolen addresses, there are still 132.95 BTC, and researchers have been unable to reproduce the seed behind these addresses, so it cannot be ruled out that the attackers obtained undisclosed private device data or candidate data.

The digital asset trading platform Gate has completed the functional upgrade of the Gate Card product, officially launching the card balance withdrawal feature. After users recharge to the Gate Card, in addition to being used for global consumption, they can also exchange the card balance for USDT at real-time exchange rates and transfer it to the Gate spot account, which can be used for subsequent trading, wealth management, or other asset allocation, further enhancing the flexibility of fund usage and management with the card.Currently, the Gate Card has integrated with the Visa and Mastercard global payment networks, covering over 200 countries and regions, and can be used at approximately 150 million merchants worldwide. It supports online consumption, offline payments, ATM withdrawals, and payment methods such as Apple Pay and Google Pay. With the launch of this withdrawal feature, the Gate Card further connects the complete chain from fund recharge, consumption use to balance return, providing users with a more flexible digital asset payment and fund management experience.

After the Coldcard hardware wallet firmware vulnerability was exploited, approximately 2,100 bitcoins were stolen, resulting in a loss of nearly $130 million. On-chain data shows that long-term holders transferred about 233,000 bitcoins from their wallets in the days before and after the incident, worth approximately $15 billion.Casa CEO Nick Neuman stated that some of the transferred funds came from Coldcard users migrating to multi-signature wallets, and Ledger and Trezor users also took similar measures after the incident. During the same period, about 22,000 bitcoins were transferred to exchanges. Coinkite has requested that users who generated recovery phrases using firmware versions 4.1 to 4.1.9 consider the related wallets compromised and immediately migrate to new recovery phrases. The aforementioned versions cover from March 2021 to July 2026.

According to official news, Bitget C2C has officially launched the merchant ecosystem recruitment. This recruitment adopts a selective and invitation-based model, with dedicated business managers providing one-on-one access.

New merchants can receive a 100 USDT onboarding reward after completing specified tasks; existing merchants can receive up to 200 USDT referral rewards for each new merchant they successfully refer, with no limit on the number of referrals. The event will last until September 30 at 23:59 (UTC+8). For more details, please refer to the Bitget official platform.

According to The Block, due to the wallet migration triggered by the Coldcard vulnerability, the number of new Bitcoin addresses surged from about 260,000 to over 330,000 last week, reversing the downward trend that persisted for most of 2026.Since July 30, Coinkite hardware wallet users have lost at least 1,816 BTC (approximately $116 million) in four waves of attacks. The vulnerability originated from a firmware defect in 2021—using a less secure software random number generator when generating mnemonic phrases instead of the device's built-in hardware entropy source, allowing attackers to brute-force wallets generated offline. Coinkite has advised users who generated wallets between March 2021 and the release of the security patch to migrate to new wallets.This incident highlights the risks associated with self-custody, as users are reassessing the pros and cons of self-custody versus custodial solutions like centralized exchanges or ETFs.

According to an exclusive report from "Du Jia," Xiaohongshu is developing a brand new "AI Shopping Guide" feature, which relies on a conversational interaction model to directly push product cards and attach order jump links in Q&A scenarios. This project is led by Daoxuan (Pan Boyuan). As of the time of publication, Xiaohongshu has not responded.Previously, Xiaohongshu launched an AI summary feature in store reputation, and this AI shopping guide is a further extension of its intelligent transaction chain.

During the 618 period, the GMV of store broadcasts increased by 265% year-on-year, and note content drove transaction growth of over 210%.Xiaohongshu currently adopts a dual transaction model of "internal marketplace closed loop plus external traffic diversion," and there is still room for improvement in the direct order conversion rate within the platform. The launch of the AI shopping guide feature is expected to further enhance its internal e-commerce GMV and revenue.

According to CoinDesk, the Pokémon trading card market is currently estimated to be between $10 billion and $15 billion, leading to queues at retailers like Costco. A Pikachu Illustrator card owned by Logan Paul once sold for $16.5 million.Sales at large chain stores like Target and Walmart, along with eBay's projected card sales of $26.2 billion in 2025, indicate that trading cards have become an important alternative asset class, recently outperforming the S&P 500 index and Bitcoin.The blockchain startup Deadstock, launched by ATH Labs, is attempting to tokenize high-grade cards and store them in a vault to address issues of market fragmentation and slow transaction speeds. The project still faces liquidity challenges and the network effect advantages created by existing platforms like eBay.

The hardware wallet Coldcard has been hacked, and the total losses are currently uncertain. The blockchain analysis platform CryptoQuant confirmed the loss to be 1432 bitcoins, while Galaxy Research provided a high-confidence minimum value of 1730 bitcoins. Other analyses suggest that the scale of the losses may be even higher.Research institution Galaxy Research stated that its earlier estimate of 1816 bitcoins is a potential value and not a confirmed total. As of Tuesday, the institution confirmed a high-confidence minimum loss of 1730 bitcoins, with over 450 bitcoins confirmed based on reports from victims. Blockchain intelligence company TRM Labs estimated that the attackers transferred about 1816 bitcoins from over 5200 addresses in four stages. CryptoQuant indicated that its confirmed data only includes addresses publicly disclosed by victims and verified through on-chain patterns, and the statistics may rise as more victims disclose information.

The insider information about the acquisition of stablecoin infrastructure company BVNK by Mastercard for $1.8 billion has recently been revealed. BVNK's early investment firm Concentric disclosed that during the acquisition bidding process, the U.S. cryptocurrency exchange Coinbase once held an advantage and reportedly made a top bid of $2.5 billion, but ultimately withdrew from the competition due to insufficient strategic and cultural fit between the two parties.Kjartan Rist, founding partner of Concentric, stated that the founding team of BVNK did not only focus on the bid amount when choosing an acquirer, but placed more importance on long-term partnerships and cultural alignment. "Although Coinbase may have offered a higher price, the chemistry between the two parties was not ideal." In contrast, Mastercard, as a traditional financial services company, found it easier to form synergies with BVNK in the areas of payment infrastructure and stablecoin applications.It is reported that Mastercard was involved in the acquisition discussions for BVNK early on, and after Coinbase failed to advance the deal, Mastercard re-emerged as the primary buyer, ultimately completing the acquisition for $1.8 billion.Visa also participated in the competition. Having previously invested in BVNK and holding a board observer seat, Visa once had an advantage. However, Visa ultimately chose not to pursue a direct acquisition, opting instead for an open strategy of collaborating with multiple stablecoin companies.BVNK was founded in 2018 and primarily provides stablecoin payment, cross-border settlement, and fund management infrastructure for enterprises. Its early investor Concentric invested in the company at a valuation of $4 million in 2019, and this transaction has resulted in significant returns.

According to Forbes, the scale of the theft in the Coldcard hardware wallet vulnerability incident has risen to approximately $130 million, involving about 2,000 BTC and over 5,200 addresses, reigniting the industry's debate over who should hold private keys. Data from Bitcoin Magazine shows that in the days following the incident, the net inflow into U.S. spot Bitcoin ETFs was $626 million, with some opinions suggesting that the vulnerability may drive more funds towards ETFs.Reports indicate that supporters of self-custody remain undeterred. Casa co-founder Jameson Lopp stated that confidence in self-custody should not be lost due to recent events, as custodial institutions also rely on random number generators. Bitcoin core early developer Peter Todd noted that the historical record of self-custody is far better than that of third parties. Another viewpoint argues that both reflexive choices have flaws. Onramp co-founder Michael Tanguma stated that if the only answer is Coinbase or ETFs, it poses a serious problem, as centralizing what should be decentralized assets undermines their foundation, advocating for a multi-institutional custody solution where keys are held by multiple regulated entities.

A wallet security incident involving approximately $130 million in Bitcoin losses is reigniting discussions in the crypto industry about asset custody models: should Bitcoin holders rely on personal self-custody or turn to institutional custody? Hardware wallet manufacturer Coldcard had a vulnerability in its firmware in 2021 that led to some mnemonic phrases generated by the device being predictably risky. This vulnerability was discovered years later, and approximately 5,200 addresses and about 2,000 BTC have been stolen, with losses amounting to around $130 million.After the incident, some investors began to turn to Wall Street custody products. Data shows that the U.S. spot Bitcoin ETF saw a net inflow of about $626 million within days of the incident. Bloomberg ETF analyst Eric Balchunas stated that such security incidents could further drive funds into ETFs. However, the Bitcoin core community still insists on the self-custody concept. Casa co-founder Jameson Lopp stated that recent events should not undermine users' confidence in self-custody and pointed out that third-party custody also carries risks. Bitcoin Core early developer Peter Todd also believes that self-custody has a better long-term safety record than centralized institutions.Onramp co-founder Michael Tanguma believes that both options have flaws. He stated that concentrating a large amount of assets in a single institution creates a "honey pot," while hardware wallets face risks related to supply chains, firmware, and random number generation. Tanguma proposed a "multi-institution custody" solution, where multiple regulated institutions hold keys through a multi-signature mechanism, requiring multiple institutions to jointly sign any transaction to reduce single points of failure. However, this model has also sparked controversy. Critics argue that while multi-institution custody enhances security, it also introduces permissioned management, conflicting with the decentralized ideals originally pursued by Bitcoin. As Bitcoin gradually enters the fields of pensions, trusts, and institutional asset allocation, the industry is seeking new custody solutions suitable for long-term wealth management. The Coldcard vulnerability incident once again highlights that achieving a balance between security, decentralization, and usability remains a core challenge facing the Bitcoin ecosystem.
