Ethereum founder Vitalik Buterin responded to Ruxandra Teslo on X, stating that he believes AI is extremely knowledgeable and can excellently identify quotes in almost any content, but it is not wise, and therefore can only make the most superficial judgments about the viewpoints a piece of writing attempts to express.Vitalik Buterin noted that this situation is particularly evident when AI analyzes text it reads for the first time, as opposed to analyzing text that already exists in the training data, which comes with a lot of analyses from others. He also mentioned that the knowledge of AI is more easily seen than its limited wisdom, as wisdom may be something that is difficult to verify easily, which is different from intelligence.This reply was directed at Ruxandra Teslo's post. Ruxandra Teslo expressed that the related post made her feel pessimistic about humanity and believed that the discussions of large language models regarding her article are still low-quality content; she was responding to Sichu Lu's statement that AI is better suited than humans to discuss classics at that time.

According to CoinDesk, XRP Ledger developers are testing a new feature that aims to allow the creation of blockchain accounts with an initial balance of zero, with existing accounts bearing the reserve required for new accounts, thereby lowering the financial threshold for payment applications and automated software to create wallets on a large scale. This proposal was submitted on October 15 in the form of a SponsoredAccountCreate transaction proposal.According to current XRP Ledger rules, each account must reserve at least 1 XRP as a reserve, meaning that creating 100,000 independent accounts would require locking up 100,000 XRP. The new proposal intends for sponsored accounts to bear this reserve requirement, and a broader fee sponsorship mechanism in the future could also allow applications to pay transaction fees on behalf of users, but the overall reserve requirement for the network will not be eliminated. This feature is expected to lower the usage threshold for scenarios such as embedded wallets, RLUSD stablecoin payments, and AI agent automated payments.However, the related code is still under review, and the sponsorship mechanism it relies on has not yet gone live on the mainnet. As of October 19, the mechanism has only received 11 votes out of the 35 required validator votes, still falling short of the 29 votes needed for approval.

Imran Khan, co-founder of Alliance, expressed his views on a16z crypto's shift towards cutting-edge technology. He stated that he is always grateful to a16z for leading the investment in Coinbase in 2013, which provided external validation for the crypto industry; Marc Andreessen's 2014 article "Why Bitcoin Matters" in The New York Times pushed him to shift his career towards Bitcoin.Imran Khan mentioned that at that time, very few institutions or funds were willing to publicly support crypto, and a16z and USV were two funds that took on brand risk. Since then, a large number of talents have entered and reshaped the crypto industry. He believes that the current infrastructure development in artificial intelligence has a practical connection with Bitcoin mining infrastructure and the talent flowing from crypto to artificial intelligence.He stated that the shift from crypto to cutting-edge technologies such as robotics, biology, artificial intelligence, energy, and computing power means that the talents and capabilities built in crypto over the past decade can be applied to a broader range of fields. He cited the resistance faced by data centers as an example, noting that crypto also faced opposition, but traditional finance has now accepted crypto to a certain extent. He believes that cutting-edge technology is the next generation of technology builders, and the world often recognizes the importance of new technologies many years later.

Ledger Wallet officially launches the Crypto Loan feature, allowing users to directly use the Morpho open credit network for lending operations within the Ledger Wallet. The core of this feature is that users can use Wrapped Bitcoin (wBTC) or cbBTC as collateral to borrow stablecoins such as USDC or USDT without selling their assets.This integration brings hardware-level security standards into the DeFi lending space. All lending activities are physically confirmed through Ledger Signer, ensuring that every on-chain interaction from deposit to loan has clear signatures and hardware-level security guarantees. During the lending process, users' collateral remains in Morpho's smart contracts, with Ledger acting solely as a technology provider.Morpho is an open credit network running on Ethereum and major Layer 2s, providing flexible lending markets through infrastructures like Morpho Blue and Morpho Midnight. This feature supports operations such as adding collateral, repaying, increasing loan limits, and withdrawals. It is important to note that this service uses floating interest rates and carries liquidation risks, and users should pay attention to the specific supported countries and lending terms.

Bitcoin has been trapped in the range of $80,000 to $84,000 for the past two weeks. Huobi HTX's chief analyst Cloud believes that this is essentially a balance of two opposing forces: ETFs have seen a net outflow for two consecutive weeks, while exchange holdings continue to flow out, and long-term holders are only moderately cashing out. In the week leading up to the Federal Reserve's interest rate decision, Bitcoin is likely to continue waiting in this range. The CME has only priced in a 16% chance of a rate hike in October, while economists generally believe it is close to a 50-50 chance. This discrepancy in pricing and opinions will make funds hesitant to bet in advance.If a direction is chosen in advance, the possibility of a downward test is slightly higher: the funding rate remains high, and the options skew continues to lean towards puts, indicating that bulls have not yet cleared out, and the demand for downside protection is still increasing. However, there has been effective support formed multiple times below $80,000 in the past month, making a downward breakout more likely to be a false breakout.Confirmation signals for a breakout are divided into two groups: for an upward breakout, the daily close needs to be above $84,200, with a cumulative net inflow of over $500 million into ETFs for three consecutive days, and the funding rate not exceeding 15%; for a downward breakout, it must fall below $79,800, with a single-week ETF outflow exceeding $500 million, while exchange funds turn into net inflows. The true source of direction will come from the interest rate decision announced at midnight on October 29, Beijing time, and the nearly 89% pricing for a rate hike in December.Note: The content of this article is not investment advice and does not constitute any offer, solicitation, or recommendation for any investment products.
