2. The New York Times: The division of crypto assets has become an important source of property disputes in divorce cases
Due to the difficulty in tracking and valuing cryptocurrencies, the division of crypto assets has become an important source of property disputes in divorce cases. Divorce lawyers reveal that in many cases, one spouse may underreport assets or transfer assets to a crypto wallet. Divorce lawyers have to spend heavily to hire court investigators to track the movement of cryptocurrencies like Bitcoin and Ethereum from online exchanges to digital wallets. The investigation firm CipherBlade has handled about 100 crypto-related divorce cases in recent years. In several cases, they tracked down over $10 million in cryptocurrencies that husbands had concealed from their wives. (Source link)

5. "Black Swan" author Taleb: Bitcoin is the "perfect fool's game" during low interest rates
Nassim Nicholas Taleb, author of "The Black Swan" and "Antifragile," has once again criticized Bitcoin on Twitter, stating that BTC is not a hedge against inflation or companies. Moreover, Bitcoin is not a hedge against geopolitical events; in fact, it is the opposite—Bitcoin is the "perfect fool's game" during low interest rates. Taleb was once very optimistic about original Bitcoin, but he completely changed his view last February. On February 12 of this year, he began selling his holdings of Bitcoin. (Source link)
6. Coinbase CEO discusses Super Bowl ad: Production cost under $100,000, aimed to showcase "some crypto-native things"
Coinbase co-founder and CEO Brian Armstrong shared the story behind the creative concept of Coinbase's Super Bowl ad on Twitter today. He stated that initially, the ad was to be produced by an external agency, but the gimmicks, celebrity endorsements, and humor were too "standard," which he did not like. So the team brainstormed internally to showcase "some crypto-native things."
However, due to time constraints, the team ultimately decided to make the entire ad a QR code, similar to a DVD screensaver theme. This inspiration also drew from Reddit's previous Super Bowl owl ad. Moreover, the flashing elements would stimulate viewers' desire to search. The final production cost was under $100,000. (Source link)
"What are the editors of Chain Catcher watching?"
A research report on digital RMB released by Anxin Securities points out that the programmable digital RMB smart contract essentially provides a conditional payment function for digital RMB. Users can make payments based on the time and conditions negotiated by both parties, thereby establishing a trust mechanism through technological means.
This feature is the most important aspect that distinguishes digital RMB from cash, deposits, and other electronic currencies. Through the programmability and conditional payment characteristics of digital RMB, it is expected to create many new currency application scenarios that were previously unattainable, greatly expanding the application boundaries of digital RMB.
2. "How to Solve the Gas Fee War and Unfair Competition Issues Caused by NFT Drops?"
Most NFT Drops (usually referring to the first issuance of NFTs in the form of a whitelist) use a first-come, first-served mechanism. However, this mechanism often leads to a rush that can cause high gas fees and result in unfair competition. This article provides specific practical improvement plans based on concrete cases, such as the NFT Drop mechanism developed by the Parallel NFT project. It will allow users to reserve NFTs off-chain. After making a reservation, users must wait 5 minutes before making another reservation. This effectively prevents bots from rushing.
3. "Hackers 'Phishing Attack' Targets OpenSea Users"
Yesterday, OpenSea CEO Devin Finzer stated that OpenSea had suffered a phishing attack, resulting in 32 users' NFTs being stolen. Many speculated on Twitter that the phishing attack link might be hidden in a fake "OpenSea to Users" email. On the 19th, the trading platform was undergoing a smart contract upgrade, requiring users to migrate their listings to the new smart contract. Attackers likely exploited this upgrade notification to disguise the phishing link as a notification email.
4. "Blockchain Games: Misunderstandings and Reality"
