The cryptocurrency industry is once again debating "who should hold the private keys" due to the $130 million theft case involving the Coldcard wallet

A wallet security incident involving approximately $130 million in Bitcoin losses is reigniting discussions in the crypto industry about asset custody models: should Bitcoin holders rely on personal self-custody or turn to institutional custody? Hardware wallet manufacturer Coldcard had a vulnerability in its firmware in 2021 that led to some mnemonic phrases generated by the device being predictably risky. This vulnerability was discovered years later, and approximately 5,200 addresses and about 2,000 BTC have been stolen, with losses amounting to around $130 million.After the incident, some investors began to turn to Wall Street custody products. Data shows that the U.S. spot Bitcoin ETF saw a net inflow of about $626 million within days of the incident. Bloomberg ETF analyst Eric Balchunas stated that such security incidents could further drive funds into ETFs. However, the Bitcoin core community still insists on the self-custody concept. Casa co-founder Jameson Lopp stated that recent events should not undermine users' confidence in self-custody and pointed out that third-party custody also carries risks. Bitcoin Core early developer Peter Todd also believes that self-custody has a better long-term safety record than centralized institutions.Onramp co-founder Michael Tanguma believes that both options have flaws. He stated that concentrating a large amount of assets in a single institution creates a "honey pot," while hardware wallets face risks related to supply chains, firmware, and random number generation. Tanguma proposed a "multi-institution custody" solution, where multiple regulated institutions hold keys through a multi-signature mechanism, requiring multiple institutions to jointly sign any transaction to reduce single points of failure. However, this model has also sparked controversy. Critics argue that while multi-institution custody enhances security, it also introduces permissioned management, conflicting with the decentralized ideals originally pursued by Bitcoin. As Bitcoin gradually enters the fields of pensions, trusts, and institutional asset allocation, the industry is seeking new custody solutions suitable for long-term wealth management. The Coldcard vulnerability incident once again highlights that achieving a balance between security, decentralization, and usability remains a core challenge facing the Bitcoin ecosystem.

hot_img The industry claims that the DRAM capacity for 2027 has been sold out in advance, with HBM accounting for nearly 70% of DRAM capacity

According to DIGITIMES, industry insiders revealed that the three major memory manufacturers have completed the capacity allocation negotiations for the entire year of 2027 in advance, with both DRAM and HBM capacities sold out. In terms of NAND Flash, although it is not as tight as DRAM, it is expected that the capacity will also be fully booked by the end of August 2026. ADATA Chairman Chen Libai confirmed that applications related to HBM and AI servers will account for nearly 70% of DRAM capacity, while the supply of DRAM for PCs and mobile phones will be relatively limited.Industry assessments indicate that Samsung, Micron, and SanDisk's NAND capacity for the entire year of 2027 has also been pre-sold, with Kioxia and SK Hynix expected to confirm by the end of August. SK Group Chairman Chey Tae-won previously stated that the demand for AI semiconductors in 2027 is expected to increase by 60-100% compared to 2026, with storage demand expected to grow by 50-60%, leading to a potential widening of the supply-demand gap and possibly facing "the most severe shortage in history." Industry insiders pointed out that the capacity allocation model is more orderly compared to 2026, but the amount that manufacturers can provide is usually only 60-70% of customer demand, leaving some small and medium buyers still facing the dilemma of having no products to purchase. The price increase of memory may slow down in 2027, but remaining high could become the norm.
