Bloomberg ETF analyst Eric Balchunas pointed out in a recent report that the performance trajectory of gold ETFs over the past 22 years may provide important references for Bitcoin ETFs. Both gold and Bitcoin ETFs are packaged products centered around "non-yielding assets," lacking dividends, interest payments, or government backing, with prices primarily driven by investor sentiment.The report states that the leading gold ETF, GLD, once topped the list of the world's largest ETFs, then experienced a prolonged period of stagnation lasting about eight years, but each cycle's peak has gradually risen. Balchunas believes that Bitcoin ETFs may similarly undergo a repetitive cycle of "rapid ascent—sharp pullback—prolonged recovery," with peaks gradually rising with each cycle.

According to CoinDesk, Runestone co-founder Leonidas announced that it is launching an open-source Bitcoin client called DOG Mode, aimed at bypassing BIP 110's restrictions on non-financial data. DOG Mode will increase the maximum weight unit for standard transactions from 400,000 to 3,900,000, close to the entire block capacity, and will reduce the dust limit from 294 to 546 satoshis down to 1 satoshi. Leonidas stated that removing the dust limit will free up approximately $25 million in idle funds.The BIP 110 proposal restricts arbitrary data through user-activated soft forks, requiring 55% miner support, which is currently close to zero. DOG Mode does not require any consensus or voting; it only needs to change the forwarding rules of a single node. If enough nodes run and miners accept, transactions can be confirmed. Leonidas mentioned that DOG Mode deviates from Core to a much lesser extent than Knots, and there is currently no code repository or version. He calls on developers to contribute code and miners to add support. The price of DOG tokens has dropped 1.2% in the last 24 hours.

According to The Block, JPMorgan analysts stated that the recent increase in cash reserves and positive capital inflows into Bitcoin futures for Strategy are "encouraging signs" for Bitcoin's prospects, although the capital flow for spot Bitcoin ETFs remains unstable.Strategy's dollar reserves have increased from $2.55 billion to $3 billion, covering approximately 20 months of preferred stock dividends. JPMorgan previously indicated that if Strategy could rebuild sufficient dollar reserves to cover two to three years of dividends, it could alleviate market concerns about the possibility of being forced to sell Bitcoin in the future.Regarding ETFs, the capital flow for spot Bitcoin ETFs has been highly volatile in recent weeks, with inflows last week turning into outflows this week. In contrast, the capital flow for leveraged ETFs related to Strategy has remained stable with continuous positive inflows over the past seven weeks. Analysts believe that this buying pressure mainly comes from retail investors, which may support Strategy's stock price and prevent its common stock from falling below the net asset value of its Bitcoin holdings. Analysts noted that despite the outflows from the spot ETF this week, Bitcoin futures still recorded positive inflows, which is encouraging.

The security company Project Eleven has launched a post-quantum proof technology aimed at helping users prove ownership of Bitcoin wallets after quantum computers can derive private keys and generate valid signatures. Project Eleven CEO Alex Pruden stated that the technology uses wallet key derivation paths, allowing users to prove their control without disclosing the parent key, which is used to distinguish legitimate owners from attackers.The solution was developed in collaboration with Jim Posen, the main maintainer of the open-source Binius zero-knowledge proof system, based on the "signature amplification" technique proposed by Alon Sattath and Robert Wyborski. Project Eleven indicated that the prototype has not yet been audited and requires blockchain protocol support before being put into use, primarily targeting users who missed the migration to quantum-resistant addresses in the future.
