Sep 10, 2026Twila Rosenbaum Hardware wallet manufacturers Trezor and BitBox issued warnings about phishing emails disguised as urgent security notices. Trezor said its email provider was breached and a message about an STM32 entropy vulnerability was fraudulent. BitBox said its newsletter provider was likely compromised and multiple Bitcoin companies may have been targeted. The alerts follow recent data exposures and firmware vulnerability disclosures in the hardware-wallet sector. View more
Sep 06, 2026Twila Rosenbaum Ripple has outlined a four-stage roadmap to protect XRP Ledger from the future threat of quantum computers, starting with vulnerability assessments and ending with emergency response plans. The effort is focused on post-quantum cryptography, validator coordination, and hybrid security deployment. It follows recent studies showing that AI-assisted techniques can drastically reduce the cost of breaking certain post-quantum signature candidates. Bitcoin and Ethereum have also published their own quantum migration plans this week. View more
Aug 08, 2026Twila Rosenbaum The Coldcard wallet exploit has analysts predicting a shift in investor behavior. Cantor sees positive read-through for crypto custody providers, while FRNT Financial says the breach could drive some investors toward bitcoin ETFs. Both firms believe the long-term impact will be adaptation rather than abandonment of self-custody. View more
Aug 08, 2026Twila Rosenbaum Coldcard wallet developer Coinkite is urging users to move their bitcoin immediately as an active exploit has already drained as much as $114 million from self-custodied wallets. The vulnerability affects specific Coldcard models and firmware versions, with wallets created via dice-roll option considered safe. The flaw has been dormant in firmware since 2021 and allows attackers to guess poorly randomized seed keys. View more
Aug 08, 2026Twila Rosenbaum A fourth wave of suspected sweeps may push Coldcard-related bitcoin losses to about $114 million. The attackers have moved roughly 1,816 BTC from more than 5,200 addresses since late July, researchers say. Unlike earlier sweeps, this latest wave uses replace-by-fee, giving observant victims a chance to rescue funds by paying higher fees. Security experts believe the issue affects single-key Coldcard seeds rather than multisignature vaults. View more
Aug 03, 2026Twila Rosenbaum AMLBot has introduced AI Tracer, a self-service blockchain analysis tool that lets non-specialists trace fund movements from a transaction hash. The tool automatically follows funds through intermediate wallets and identifies exchanges, services, and flagged addresses. It supports major networks such as Bitcoin, Ethereum, Solana, and Ripple. While it doesn't replace audits or legal processes, it offers a free check and paid plans for higher usage. View more
Jul 17, 2026Twila Rosenbaum BIP-110 sought to restrict certain types of transaction data on Bitcoin's blockchain, sparking a fierce debate over censorship and decentralization. The proposal has gained little support from miners and the wider industry, making its activation unlikely. This article explores the origins of BIP-110, the arguments for and against, and the broader implications for Bitcoin's governance. View more
Jul 16, 2026Twila Rosenbaum The BIP-110 proposal to temporarily restrict non-financial data on Bitcoin faces an early August deadline with miner support below 1%. Backers say it refocuses Bitcoin on payments, but critics like Michael Saylor and Adam Back argue it censors valid transactions. With node adoption also in low single digits, BIP-110 appears likely to create a minority chain rather than a network-wide change. View more
Jul 16, 2026Twila Rosenbaum Bitcoin advanced past $64,000 on Friday, recovering from earlier losses as investor sentiment improved. The rally was fueled by strong demand for AI-linked stocks, with SK Hynix's U.S. IPO surging 14% at market open. Circle Financial also gained after securing a national trust bank charter, while crypto ETFs saw mixed flows. The bitcoin-to-gold ratio approached a key resistance level, signaling renewed bullish momentum for the leading cryptocurrency. View more
May 24, 2026Twila Rosenbaum Recent analysis highlights that quantum computing breakthroughs are arriving faster than expected, raising risks for cryptocurrency security systems. Bitcoin is seen as particularly exposed due to its slower governance and upgrade process. Ethereum and other proof-of-stake networks may adapt more quickly, but face their own quantum-related risks. The timeline for quantum threats to break current encryption is now considered significantly shorter than previously thought. View more
May 24, 2026Twila Rosenbaum VerifiedX is developing a Bitcoin sidechain designed to enable programmable, privacy-preserving decentralized finance (DeFi) without relying on synthetic wrappers or custodians. The project aims to unlock native bitcoin for lending, trading, and yield generation while maintaining privacy. This comes as institutional interest in privacy-focused crypto infrastructure increases, with tokens like zcash gaining renewed attention. View more
