According to information obtained by Wu Blockchain, CryptoRank data shows that the average cash cost for publicly listed mining companies to mine 1 BTC has reached approximately $74,600. When depreciation and stock-based compensation (SBC) are included, the total cost rises to about $137,800. As the total Bitcoin network hashrate surpasses the symbolic threshold of 1 ZH/s, competition has intensified significantly, mining profits have rapidly declined, and some mining companies have begun shifting their hashrate and data center assets to AI/HPC (high-performance computing) businesses in pursui

Two long-dormant wallets associated with Casascius physical bitcoins recently transferred about 2,000 BTC, worth approximately $180 million, after being untouched for over a decade. These BTC had not been moved since 2011 and 2012, when the price of bitcoin was less than $15, compared to nearly $90,000 today. Casascius was once a physical offline storage solution with embedded private keys, but production ceased in 2013 due to regulatory pressure from FinCEN. Currently, around 90,000 physical coins remain in circulation, most containing only small amounts of BTC, with only 6 coin and 16 bar ve

According to Fortune, the U.S. Department of Justice has announced federal charges against former DEA senior agent Paul Campo, who served for 25 years, and his accomplice Robert Sensi. The two are accused of laundering money, assisting in the purchase of military-grade weapons and explosives for Mexico’s Jalisco New Generation Cartel (CJNG). The indictment shows that they agreed to launder approximately $12 million in drug proceeds for the cartel, and had already converted about $750,000 in cash into cryptocurrency, believing the funds would be transferred to the drug cartel, but the money was

According to the latest "Euro Stablecoin Trends 2025" report by London payment company Decta, the market capitalization of euro stablecoins doubled within a year after the implementation of regulations in June 2024, reversing the previous year's 48% decline; EURS, EURC, and EURCV led the growth. Monthly trading volume rose from $383 million to $3.8 billion, an increase of nearly 9 times. The current market capitalization of euro stablecoins is about $680 million, still far smaller than the $300 billion scale of US dollar stablecoins.

According to Wu Blockchain, Bloomberg ETF analyst Eric Balchunas stated that Bitcoin's performance over the past year has essentially been a pullback from last year's extreme surge—Bitcoin rose 122% in 2024, about five times more than other assets. Even if its performance in 2025 is flat or declines slightly, as long as it maintains an average annual growth rate of around 50% over the long term, periodic cooling is normal; the same applies to stocks. The current market is overinterpreting this situation.

Wu Shuo has learned from SolanaFloor that the Solana community has recently raised concerns about the risk disclosure of Jupiter Lend. Samyak Jain, co-founder of Fluid, admitted that Jupiter Lend’s vaults engage in rehypothecation to improve capital efficiency and are “not fully segregated.” Marius, co-founder of Kamino, pointed out that this contradicts Jupiter’s previous claims of “no risk contagion.” In practice, when users collateralize SOL to borrow USDC, their SOL is rehypothecated into loop positions including JupSOL, INF, and others. Users bear full exposure to any risk events involvin

According to WuShuo, citing Caixin reports, in recent years, leveraging the decentralization, anonymity, and convenient cross-border mobility of virtual currencies, there has been a surge in money laundering, illegal fundraising, fraud, and illicit cross-border fund transfers, all of which disrupt economic and financial order and threaten public property security. Data shows that in 2024, relevant authorities prosecuted a total of 3,032 individuals in money laundering cases involving the use of "virtual currency" to transfer criminal proceeds. Many defendants became involved due to a lack of l

WuShuo has learned, according to Zhitong Finance, that Wu Qing, Chairman of the China Securities Regulatory Commission, recently stated at the 8th General Assembly of the China Securities Association that the boom in financial technology innovation is profoundly changing and even reshaping the financial market ecosystem. Industry institutions must be adept at embracing change, adapting to change, and seeking change by actively researching, steadily exploring, and promoting the deployment and application of technologies such as artificial intelligence, big data, and blockchain in the capital ma

Western Union is developing a prepaid stablecoin payment card aimed at countries experiencing severe inflation. The company's CFO, Matthew Cagwin, stated at the UBS Global Technology and AI Conference that the product is designed to help address scenarios of rapid local currency devaluation, providing users with more stable purchasing power. For example, in Argentina, inflation exceeded 200% last year, and a dollar-denominated stablecoin card can help remittance recipients better preserve value. Previously, Western Union also announced plans to launch the USD-pegged stablecoin USDPT on Solana

Minh Phuong Ngoc Vong, a man from Maryland, USA, was sentenced to 15 months in prison and 3 years of supervised release for assisting North Korean IT personnel in infiltrating American tech companies. Between 2021 and 2024, he used forged identities to secure software positions for at least 13 U.S. companies, with the actual work being performed remotely by his North Korean associates. Some of the projects involved access to sensitive government systems such as those of the FAA.

According to Yahoo Finance, Aave founder Stani Kulechov stated that the UK HMRC’s (Her Majesty’s Revenue and Customs) latest DeFi tax guidelines could become a major turning point for crypto lending. The policy explicitly states that depositing assets such as USDC and USDT into DeFi will not be considered a disposal and will not trigger capital gains tax, with tax only applied upon actual sale or exchange—essentially a “no gain, no loss” treatment. Kulechov said this will reduce compliance costs, benefit both institutional and retail adoption, and boost DeFi liquidity and lending growth in the

According to Wu Blockchain, SlowMist’s Cosine posted on X that user Babur disclosed the theft of approximately $27 million in crypto assets. Analysis shows that the stolen assets were mainly concentrated in two addresses: Solana address 91xu and Ethereum Safe multisig address 0xD2, with the two largest stolen amounts totaling over $18 million. Some of the funds have already been bridged to the Ethereum network. Cosine stated that the incident is suspected to have been caused by a trojan infection on the computer, and after the user double-clicked a malicious file, the private keys were leaked.

James Butterfill, Head of Research at CoinShares, responded to recent controversies regarding Tether’s solvency, noting that despite new criticisms from Arthur Hayes and S&P Global, Tether currently has billions of dollars in surplus and market panic is “somewhat misplaced.” He cited Tether’s latest audit report, stating that the company currently holds $181 billion in reserves against approximately $174.45 billion in liabilities, resulting in a surplus of nearly $6.8 billion. Tether remains one of the most profitable companies in the industry, generating $10 billion in profits in the first th
