Is bitcoin self-custody safe? ETF alternative gains traction after Ledger security shock

A reported case of an unauthorized component being inserted into a Ledger hardware wallet has reignited debate over how to store bitcoin. The industry is split over whether self-custody, in which individuals manage assets directly, is safer than holding bitcoin through spot exchange-traded funds run by custodians. The incident highlighted physical security and supply-chain trust issues. Supporters of ETFs cite reduced security burdens, while critics warn that concentrating assets with a few custodians could create new single points of failure.

Can guessing 24 words steal Satoshi\'s bitcoin? Experts say it would take 13.8 billion years

A claim spreading on X said bitcoin believed to be held by Satoshi Nakamoto could be stolen by correctly guessing a 24-word phrase. Researchers said the premise is unrealistic. Even with computing power generating 1 trillion combinations per second, it would take about 13.8 billion years to find a specific 24-word seed phrase with a 50 percent chance. They also said Satoshi’s coins are spread across more than 22,000 older addresses, not a single seed-based wallet.

Tom Lee warns 35 percent of bitcoin supply could be exposed to quantum threat within 3 years

A warning has emerged that about 30 to 35 percent of bitcoin’s total supply could be exposed to quantum-computer attacks in 2028 to 2029. Fundstrat co-founder and Bitmine chairman Tom Lee said quantum computing could undermine bitcoin’s existing security system. He said the crypto industry has no unified response, while the Ethereum and Solana ecosystems are better prepared. Adam Back disputed Lee’s technical claims, saying bitcoin ownership is protected by ECDSA digital signatures and seed-phrase entropy.
