Arkham posted on the X platform that Avi Eisenberg, the attacker who profited approximately $110 million in 2022 by manipulating the price oracle of Mango Markets, has recently signed a transaction with his on-chain address, drawing widespread attention from the community.Avi Eisenberg previously exploited a vulnerability in Mango Finance to conduct "high-profit trades," and later threatened to attack Aave.

Bitcoin developer Paul Sztorc announced the official launch of the Bitcoin hard fork network eCash, allowing BTC holders to exchange BTC for eCash at a 1:1 ratio after the hard fork goes live.It is reported that the Layer1 node software of this network will be an "almost replica" of the Bitcoin Core client, continuing to use the SHA-256 hashing algorithm and lowering the initial mining difficulty to attract more miners to participate. Meanwhile, eCash will also be equipped with seven Layer2 scaling networks called "drivechains" to enhance transaction throughput and support optional on-chain privacy features. Paul Sztorc stated that eCash is different from Bitcoin Cash in 2017, no longer using the "Bitcoin" name, and claims it is a long-term solution to Bitcoin's scalability and privacy issues. However, the proposal to manually reallocate a portion of Satoshi Nakamoto's approximately 1.1 million BTC to early investors has sparked strong controversy in the community, with some Bitcoin supporters criticizing the move as "theft" and a violation of Bitcoin principles.

The DeFi Education Fund, along with Aave Labs, Uniswap Labs, Paradigm, Andreessen Horowitz, and other organizations, has sent a letter to the U.S. SEC in response to the recent statement released by the trading and markets division regarding the registration of "non-custodial user interface" brokers for crypto asset securities.The signatories support the statement that the "non-custodial user interface," which only provides a technical entry point and allows users to manage their assets independently, should be excluded from broker registration. They also urge the SEC to establish clearer and more sustainable definitions of "broker" through formal rulemaking, to avoid incorrectly categorizing neutral software tool providers, validators, RPC/API, oracles, cloud services, and other infrastructure under broker regulations. This would provide long-term legal certainty for blockchain infrastructure innovation while ensuring investor protection.Previously, the SEC's trading and markets division indicated that some DeFi trading interfaces do not need to register as brokers, allowing for policy space for related applications. Supporters believe that the new regulations could cover infrastructure participants such as validators, APIs, and oracles. Currently, the U.S. crypto market legislation, the CLARITY Act, is stalled in the Senate.

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) announced sanctions against Cambodian Senator Kok An, accusing him of controlling "fraud parks" across the country, defrauding American victims through cryptocurrency investment scams.According to a statement released by OFAC on Thursday, in addition to Kok An, 28 other individuals and entities have been added to the sanctions list, all believed to be connected to his fraud network. This network is accused of luring victims into sending cryptocurrency assets under the guise of "high return investments." This action follows a raid by Cambodian police on two scam centers in the border city of Poipet. Previously, Kok An had been accused of operating scam bases in the area. OFAC stated that scammers typically gain victims' trust by establishing "friendships" or "romantic relationships," then guide them to participate in so-called cryptocurrency investment platforms, thereby defrauding them of funds, with the total amount involved reaching millions of dollars.It is noteworthy that some individuals involved in the scam activities are themselves victims of human trafficking, forced to engage in illegal activities under threats of violence. OFAC pointed out that these scam centers are often located in casinos or repurposed office parks, used not only for money laundering but also as bases for defrauding American citizens and committing human rights violations. Additionally, regulators have simultaneously shut down over 500 fraudulent website domains used for cryptocurrency investment scams, indicating that the U.S. crackdown on related criminal activities is intensifying.

Liquid Capital founder Jack Yi stated on the X platform: "In the past, the wave of crypto VC and project disappearances had a core reason, which is that the financing funds were mostly consumed on: maintaining teams to develop useless web3 products. The biggest misconception is benchmarking against web2 products. Essentially, web3 is a financial industry and does not need to replicate web2 products. The most successful companies in the past crypto industry have all been financial products, from stablecoins and exchanges to successful companies in payments.Now that the AI era has arrived, first, there is no need for large financing to recruit teams, and second, AI + finance presents new opportunities. We believe that excellent founders with a few elites can achieve top-tier companies, which is currently the biggest opportunity in primary investment."

U.S. President Trump stated: (Regarding negotiations with Iran) I believe we will ultimately reach a great agreement. Iran has no choice but to send people to the negotiations. We are in a very favorable position in our negotiations with Iran. (Talking about Iran) This is regime change. Our negotiations with them have been very successful. The U.S. completely controls the Strait of Hormuz. The blockade has been a tremendous success. (Regarding a ceasefire with Iran) We don't have that much time. We don't want to extend the ceasefire again. Iran can improve its situation by reaching an agreement. Iran has just been allowed to go to Pakistan for talks. Iran can make itself a legitimate country. Iran seems to be "bloodthirsty." Iran must be rational and use common sense. Strikes on infrastructure could cause military damage to Iran. Iran is trying to move its missiles. We have much more equipment now than we did a few weeks ago. Our posture is ready to bomb Iran, and we are prepared.

Liquid Capital (formerly LD Capital) founder Yi Lihua stated that recently the focus has been on rebounds rather than reversals, so the key is where the rebound will go. It was originally expected to reach $85,000, but no one can pinpoint it accurately. The important thing is to take profits based on one's own expectations and risk control.From a trading and cyclical perspective, there may still be one major correction, which would be an excellent final buying opportunity. Currently, the triggering factors may be the pullback of U.S. stocks from historical highs, the decline of risk assets, and the uncontrollable oil prices. Terrifying inflation data could lead the Federal Reserve to abandon interest rate cuts and even consider raising rates. The outlook for investment is optimistic in the medium to long term, while managing risks in the short term.
