AI computing power financing is heating up, and Lambda, supported by Nvidia, plans to purchase GPUs through a $917 million loan

Lambda, an AI cloud computing service provider supported by Nvidia, is financing $917 million through the leveraged loan market to procure AI chips. As the construction of artificial intelligence infrastructure accelerates, chip financing is becoming a new way for capital investment in the AI industry. Lambda belongs to the rapidly developing "new cloud vendor" camp in recent years, with its main business being to provide GPU computing power and AI infrastructure services to enterprises and developers.This financing plan will be completed through a loan based on GPU asset-related rights, aimed at supporting the company's expansion of AI computing resources. Reports indicate that AI infrastructure companies are actively exploring new financing methods to meet the enormous capital investment required for building large-scale computing clusters. Previously, AI cloud service provider CoreWeave completed the first transaction in the institutional leveraged loan market for chip financing, providing a new financing model for the industry. As the demand for generative AI continues to grow, Nvidia's GPU supply has become a core resource for AI companies' expansion. By using GPU assets as the basis for financing, AI cloud service providers can rapidly scale their computing power without fully relying on equity financing, while also allowing the traditional credit market to participate in the wave of AI infrastructure investment.

Russian President Putin signs laws regulating digital currencies and digital rights

According to a report by China News Service, Russian President Putin signed a law on the 4th to comprehensively regulate digital currencies and digital rights in Russia. Relevant documents have been published on the Russian legal information website. The law clarifies the operational rules for cryptocurrency exchange platforms, digital asset custodians, and other market participants, and regulates the conditions under which investors can purchase cryptocurrencies.The law regulates relationships related to the circulation, accounting, and storage of digital currencies and foreign digital tools, as well as activities related to "mining," and the issuance and circulation of digital rights. It also stipulates the regulation of the business operations of information system operators for issuing digital financial assets, cryptocurrency exchange institutions, digital asset custodians, brokers, asset management companies, trading organizers, and clearing institutions. According to this law, Russian citizens can legally invest in cryptocurrencies through exchanges within Russia and use services provided by brokers, trust managers, asset management companies, and cryptocurrency exchange institutions when conducting cryptocurrency transactions and related operations.The registration and custody of cryptocurrencies will be the responsibility of relevant digital custodians approved by the Central Bank of Russia, and market participants must comply with strict information security requirements. The Central Bank of Russia will also establish a registration list for cryptocurrency exchange institutions, which will include credit institutions and brokers under a filing system for management. This law will officially take effect on September 1, but some provisions will be implemented on July 1, 2027, or September 1, 2027.

Jim Cramer said he will liquidate his Bitcoin holdings, concerned about the threat of quantum computing to its security

Former hedge fund manager and CNBC host Jim Cramer stated that due to concerns about quantum computing threatening Bitcoin's security, he plans to sell all of his BTC holdings. His statement stems from an interview with IBM Chairman and CEO Arvind Krishna, who said that investors should be wary of the challenges quantum computing may pose to modern cryptography in the next 3 to 4 years. Cramer believes that quantum computing could threaten the Bitcoin network in a similar timeframe. However, no one has independently confirmed how much BTC he holds or whether he has completed the sale.After his statement, Bitcoin continued to trade normally around $63,764, with some market participants viewing his comments as a "reverse Cramer" signal. Bitcoin uses the ECDSA signature mechanism based on the secp256k1 curve, and theoretically, a sufficiently powerful quantum computer could use Shor's algorithm to derive the private key from the public key. The risk is mainly concentrated on addresses with exposed public keys, including reused addresses, early wallet formats, and the brief time window after a transaction is broadcast but not yet confirmed. Researchers estimate that about 6 to 7 million BTC, accounting for approximately 30% of the supply, may fall into this category. Google Quantum AI estimated in March this year that breaking the relevant cryptographic mechanisms could require fewer than 500,000 physical qubits, reducing the previous estimate by about 20 times. However, current quantum systems typically only have hundreds to thousands of physical qubits, with even fewer logical qubits that have higher reliability. Most researchers expect that truly capable quantum computers for cryptographic breaking may not appear until the 2030s or even 2040s, making Cramer's 3-year prediction significantly earlier than most technological expectations.

Vaulted CEO: Quantum computing may "end" BTC in the next 4 years

According to Forbes, Vaulted CEO David McAlvany stated that he believes Bitcoin could disappear within the next four years due to quantum computing. He mentioned that once quantum computers can quickly solve the mathematical problems protecting Bitcoin private keys, "that will be the end of Bitcoin."However, McAlvany later admitted that he cannot determine whether the relevant breakthrough will occur in four years, five years, or two months. As of mid-2026, there are no quantum computers capable of cracking Bitcoin's encryption algorithms. His viewpoint is mainly based on concerns about the future development speed of quantum computing, rather than on already occurred security events.Galaxy Digital estimates that approximately 7 million BTC addresses have exposed public keys on-chain, worth about $470 billion; Glassnode's estimate is 6.04 million, accounting for 30.2% of the Bitcoin supply. Exposing public keys does not equate to assets being stolen; only when quantum computers can reverse-engineer private keys from public keys might these addresses face actual theft risks.McAlvany also compared Bitcoin to gold and questioned whether Bitcoin could exist for 5,000 years. He expressed relative confidence that gold will still exist by then, but Bitcoin "might exist, or it might not."Bitcoin developers currently have differing opinions on solutions. BIP-360 proposes to add quantum-resistant address types; BIP-361 plans to phase out support for old-style signatures, with assets that do not migrate in time potentially being permanently frozen, including those believed to belong to Satoshi Nakamoto. Supporters argue that freezing assets is better than allowing quantum attackers to steal and sell them, while critics view it as confiscation.Companies like BOLTS Technologies and American Fortress are also developing cross-chain quantum-resistant solutions. American Fortress completed an $8 million seed round in May and claims its technology can protect assets without requiring users to migrate addresses, but the relevant technical papers have not yet been published, and the design has not undergone public auditing.
