According to CoinGlass data, the Coinbase Bitcoin Premium Index has recorded negative values for four consecutive days, with the latest at -0.0082%, as purchasing power in the U.S. market has once again fallen into a slump.Previously, on August 24, the Coinbase Bitcoin Premium Index reappeared with a positive signal for the first time since May 19, reporting 0.0052%, temporarily ending the historically longest negative premium period of 97 days. The Coinbase Bitcoin Premium Index is used to measure the price difference of Bitcoin between Coinbase Pro and Binance. A sustained negative index typically indicates that Coinbase's pricing is relatively low, which may reflect weak buying interest or significant selling pressure in the U.S. market, but it is not advisable to directly conclude that institutional funds are flowing out based solely on this indicator.

According to documents submitted by Riot Platforms to the U.S. Securities and Exchange Commission (SEC), the company voluntarily repaid all outstanding loans and accrued interest to Coinbase Credit on September 21, and terminated the previously established credit line of $200 million, without incurring any early termination fees or penalties.The loan had previously been fully drawn by Riot, with a fixed annual interest rate of 6.15%, and an original maturity date of April 20, 2027. As of June 30, Riot had pledged 5,821 BTC as collateral for the loan, valued at approximately $340.7 million, accounting for about 51% of the total BTC held by the company at that time; with the loan repayment, Coinbase's security interest in the related collateral assets was simultaneously released. Riot initially obtained a $100 million Bitcoin collateral loan in April 2025, increasing the limit to $200 million the following month. This repayment occurred approximately 7 months ahead of the revised maturity date.

Emilie Choi, President and Chief Operating Officer of Coinbase, stated that Coinbase is one of the first supporters of the "Trump Account" plan. Faryar Shirzad, Chief Policy Officer of Coinbase, mentioned that the company has submitted opinions to the Internal Revenue Service regarding the implementation and expansion of the account, suggesting that beneficiaries be allowed to invest in a wide range of traded digital assets or gain exposure to digital assets through funds, aligning the scope of qualified investments with the asset classes that traditional IRAs can invest in. Coinbase believes that broader and product-neutral rules will help expand choices, promote competition, and provide more opportunities for young people in the United States to engage in diversified investments and wealth accumulation. The qualified investments proposed by the Internal Revenue Service in the growth phase are currently mainly limited to tracking a broad stock index of U.S. companies, unleveraged mutual funds or ETFs with an annual fee rate not exceeding 0.1%.

Coinbase launches Bitcoin-collateralized fixed-rate, fixed-term USDC loans through Morpho Midnight, allowing borrowers to obtain USDC without selling their Bitcoin. The interest rate and repayment date for the product are determined at the start of the loan; if borrowers do not repay the USDC and interest before the due date, the collateralized Bitcoin may be reclaimed.The existing active or outstanding loan volume of Bitcoin-collateralized loans with floating rates supported by Morpho at Coinbase has exceeded 1.4 billion dollars, with collateral valued at approximately 3 billion dollars.

Coinbase Chief Cryptographer Yehuda Lindell stated on the MARA Foundation TV program that the exchange is designing a custody system capable of adapting to any post-quantum signature scheme that Bitcoin may adopt in the future. It is currently unclear which post-quantum signature scheme Bitcoin will use in practical applications. Lindell believes it is unlikely that a single signature scheme will be universally adopted, so preparations must be made for different outcomes across various blockchains.Coinbase is custodian for approximately $250 billion in assets for institutions such as BlackRock. Traditional Multi-Party Computation (MPC) relies on key sharding, but many post-quantum signature schemes may be "not friendly to MPC"; for example, hash-based signatures lack the arithmetic structure required for traditional cryptographic key splitting. Although cryptographers like Dan Boneh are researching relevant solutions, this research is still in a highly experimental phase, and it remains uncertain whether a viable MPC-like solution for hash signatures can be developed.To this end, Coinbase is exploring a backup architecture centered around programmable Hardware Security Modules (HSM), where private keys will be encrypted with post-quantum cryptography and assembled only within physically secure HSMs. Lindell stated that while the completion timeline is uncertain, once finished, "I will be able to say, I can support any scheme," without worrying about a blockchain adopting a signature scheme that it cannot support.
