Bitcoin2026-10-21 13:30:00Five alternatives to hardware wallets for storing Bitcoin, from ETFs to multisigCointelegraph has outlined five alternatives to hardware wallets for storing Bitcoin and other crypto assets, arguing that recent incidents tied to Ledger and Coldcard have pushed more holders to reassess how they manage custody. The report says more than $200 million in crypto was stolen in recent months from tampered Ledger devices and from Coldcards where the generated seed was not truly random, raising questions about risks that can exist even when users buy from official sources and store seed phrases correctly. The piece also points to a rise in physical attacks on crypto holders, citing a so-called "$5 wrench attack" in France every 2.5 days this year. Against that backdrop, it reviews five storage routes: crypto ETFs, passkey-based wallets, multisignature wallets, centralized exchanges and paper wallets. Each option removes some burdens while introducing different trade-offs around custody, recovery, privacy, fees, code risk or reliance on third parties. Comments cited in the article include 21Shares co-founder Ophelia Snyder, who said exchange-traded products make sense for most people most of the time for tax, estate planning and security reasons, and PlanB, who said he had "zero regrets" about moving BTC to ETFs in 2025. The report’s core conclusion is that there is no single ideal storage method, and that users may reduce damage by spreading holdings across different addresses and custody models.20
Vitalik Buter2026-10-08 00:08:58Vitalik Buterin warns AI could weaken post-quantum cryptography within two years, advises against rushed fund transfersEthereum co-founder Vitalik Buterin said advances in AI-driven mathematical research could materially weaken the real-world security of lattice-based cryptographic systems such as ML-DSA and fully homomorphic encryption, or FHE, within the next two years. He also said the same trend could bring forward the timeline for risks to ECDSA, making it vulnerable earlier than previously expected. Buterin wrote that AI may compress decades of mathematical progress into a much shorter period, estimating that two years of AI-assisted work could amount to roughly 50 years of traditional research. In response to that possibility, he said Ethereum’s Lean roadmap has gradually shifted over the past year toward pure hash-based signature schemes in order to reduce reliance on lattice cryptography. On user security, Buterin said funds should preferably be kept in addresses that have never initiated a transaction, when practical. At the same time, he cautioned against moving assets in a hurry, saying the transfer process itself carries a risk of loss. He also recommended that multisig wallets use off-chain signature confirmation where possible so signature data is not publicly exposed.320
Vitalik Buter2026-10-08 00:09:05Vitalik says AI could weaken post-quantum cryptography within two years, urges users not to rush asset transfersEthereum co-founder Vitalik Buterin warned on Oct. 8 that AI-driven advances in mathematics could materially weaken the real-world security of lattice-based cryptographic systems within the next two years. His warning covered technologies tied to ML-DSA and fully homomorphic encryption, and he said ECDSA could also face break risks earlier than previously expected. Buterin argued that AI may compress decades of mathematical progress into a much shorter period, saying it could deliver research gains in two years comparable to the past 50 years. Against that backdrop, he said Ethereum’s Lean roadmap has gradually shifted over the past year toward pure hash-based signature schemes in an effort to cut reliance on lattice cryptography. On user security, Buterin said funds should preferably be stored in addresses that have never initiated a transaction, where practical. At the same time, he cautioned against hasty migration of assets, noting that the transfer process itself carries a risk of loss. He also advised multisig wallets to use off-chain signature confirmation whenever possible so signature information is not publicly exposed.280
Ondo2026-08-19 03:04:33Ondo-linked wallets send another 13.43 million ONDO to CoinbaseOndo-linked addresses have transferred another 13.43 million ONDO to Coinbase, according to on-chain analyst Ai Yi. The monitored wallets were identified as 0xFA06...8223 and 0xEA57...75e1. Ai Yi said the related addresses appear to have sold ONDO worth $29.94 million over the past 30 days. In the latest activity, two multisig wallets moved tokens worth $4.42 million to Coinbase over the past 10 hours. Despite those transfers, the linked addresses still hold ONDO worth $12.68 million on-chain. The update was reported by Odaily as a brief market item and did not include any additional statement from the Ondo team or Coinbase. The report focuses on the latest wallet movements and the scale of recent suspected selling tied to the addresses being tracked.1960
Changpeng Zha2026-07-23 13:13:06CZ credits BitMEX for early 100x leverage launch and security-focused operating rulesBinance founder Changpeng Zhao said in a post that BitMEX was the first crypto platform to introduce 100x leveraged futures trading back in 2014, pointing to the exchange’s early product design and strict operating setup. Zhao said BitMEX ran for years with a narrow structure: it accepted only Bitcoin deposits, operated on a single chain, limited withdrawals to once per day, and used multi-signature wallets to manage funds. He said those restrictions helped the exchange avoid hacker attacks. Zhao also referred to the legal case involving BitMEX’s four founders. According to his post, they had previously been accused of violating the Bank Secrecy Act and pleaded guilty one month before trial. He said each founder was fined $10 million and placed under house arrest, while none received a prison sentence. Zhao added that the company’s business ultimately did not continue under what he described as regulatory pressure.1860
