News linked to both this project and an event.
Odaily News: After a firmware vulnerability in Coldcard hardware wallets was exploited, approximately 2,100 Bitcoin were stolen, with losses nearing $130 million. On-chain data shows that in the days surrounding the incident, wallets held by long-term holders transferred out approximately 233,000 Bitcoin, valued at around $15 billion. Casa CEO Nick Neuman stated that some of the transferred funds came from Coldcard users migrating to multi-signature wallets, with Ledger and Trezor users also taking similar measures after the event. During the same period, approximately 22,000 Bitcoin were transferred into exchanges. Coinkite has advised users who generated seed phrases using firmware versions 4.0.1 through 4.1.9 to treat their wallets as compromised and immediately migrate to new seed phrases. These versions cover the period from March 2021 to July 2026. (Decrypt)
hardware wallet company Trezor stated there is a distinction between Bitcoin self-custody and holding Bitcoin credit exposure. When users store assets on exchanges, brokerages, or funds, they are actually relying on third-party ledger records and withdrawal arrangements. The company noted that after the full implementation of new EU crypto regulations, some exchanges that failed to obtain licenses in time have stopped offering regulated services to EU users. Trezor stated that its founders Marek Palatinus and Pavol Rusnák launched the first hardware wallet 12 years ago, moving private keys from internet-connected computers to dedicated devices. Trezor explained that private keys are generated on the device and never leave it, with transactions being signed inside the device before being sent. Trezor CCO Danny Sanders previously stated that if users put Bitcoin into ETFs and call it Bitcoin ownership, it would be one of the worst outcomes for the industry. Trezor estimates that among approximately 600 million global crypto users, about 10% self-custody their private keys, and around 12 to 13 million people use hardware wallets.
: Danny Sanders, Chief Business Officer of hardware wallet manufacturer Trezor, stated that "putting everything into ETFs" might be the worst development path for the Bitcoin ecosystem. Since the launch of US spot Bitcoin ETFs in early 2024, cumulative inflows have exceeded $53 billion, making them a significant driver of BTC prices, but also potentially altering the structure of how users hold their assets.Sanders believes that over-reliance on ETFs will weaken Bitcoin's core principle of "self-custody," gradually shifting asset control to third-party institutions instead of users holding their private keys. Although self-custody carries risks such as lost seed phrases or unrecoverable private key leaks, he considers these more of a psychological barrier than a technical challenge, adding that "it's not difficult once you actually start doing it."Data shows that out of approximately 600 million crypto users globally, only about 10% practice self-custody, and only around 12 to 13 million users employ hardware wallets.As an early hardware wallet provider in the industry, Trezor helped popularize the BIP-39 seed phrase standard and continues to advocate for lowering the barriers to self-custody through improved user experience and educational tools, rather than relying on intermediary custody.Sanders concluded that the industry's long-term goal should be to gradually approach a Web2-level user experience, rather than simply replacing self-custody with ETFs. "That would probably be the worst possible outcome for the entire industry." (The Block)
