Bitcoiners turn to dice throws as self-custody setups are re-evaluated

In light of the catastrophic low-entropy bug in Coldcard hardware wallets, linked to publicly observed thefts beginning on July 30, Bitcoin holders have started to re-evaluate the trust assumptions in their hardware wallet setups.　　How Coldcards entropy flaw worked　　The Coldcard devices were equipped with apparently functional STM32 “true random number generators” (TRNGs) that rely on physical processes to produce an unguessable seed phrase.　　However, after Coldcard creator NVK decided to initiate a firmware rewrite to switch from a GPL-licensed free software model to a read-only model, a serious vulnerability appears to have been introduced.　　Starting with firmware version 4.0.1, released in March 2021, the device used MicroPythons Yasmarang PRNG instead of properly using the STM32 hardware RNG.　　Random number generation is an unsolvable problem in computer science, which is why the generation of secure, unguessable private keys always has to rely on external physical processes to a degree.　　The use of the Yasmarang PRNG was widely characterized by analysts in the space as a pre-programmed fallback. However, Coinkite has now disputed this characterization in a recent X post:　　The conjecture that Coldcards were programmed to default to an obviously insecure method of seed generation has also sparked speculation on X about whether this was a deliberately

Bitcoin developer says self-custody fears cost him gains

German Bitcoin developer René Pickhardt said on Aug. 6 that fears about self-custody security and key management kept him from accumulating more Bitcoin, despite believing the asset had upside.　　In a post, Pickhardt wrote that “security they describe the operational burden individual holders accept.　　Blockstream CEO Adam Back responded that “with great bearer cash power comes great responsibility to not lose your keys.” The response captures the trade-off: Bitcoin allows holders to control assets without a bank, but no central institution can reset a lost private key or reverse an unauthorized valid transaction.　　Coldcard losses sharpen the self-custody debate　　Recent wallet security incidents give that debate context. Cinco Días, citing Galaxy Research, reported that roughly 1,755 BTC had been stolen from about 5,000 wallets across several waves. Earlier Galaxy estimates were lower, and Coinkite has said the full attribution and scope remain unresolved, so the figure should be treated as an evolving on-chain estimate rather than a final confirmed loss.　　The failure also does not show that every hardware wallet faces the same flaw. Block said its products were unaffected, while other manufacturers have separately explained their entropy-generation designs. The vulnerability followed affected seed phrases even if users imported them into another wallet, meaning changing

Bitcoin Telegram accounts targeted by North Korean hackers

Bitcoiners are facing a renewed warning over an active social-engineering campaign that hijacks trusted Telegram accounts and funnels cryptocurrency professionals into fake Zoom or Microsoft Teams meetings.　　Lightning News raised the alarm on Aug. 7, citing recent accounts from Bitcoin community members. Independent security research confirms the core attack chain, though not every claim has been verified.　　JUMPSEC said in July that it obtained source code from an active BlueNoroff phishing kit after exposed JavaScript source maps. The researchers found a victim-acquisition platform that abuses compromised Telegram contacts, profiles cryptocurrency wallets and delivers malware to selected targets on Windows and macOS systems. JUMPSEC said identified campaign infrastructure remained active as of July 22.　　Telegram accounts under attack, source: XBlueNoroff turns trusted Telegram contacts into lures　　The attack begins with trust rather than a blockchain vulnerability. JUMPSEC found operators using compromised Telegram accounts belonging to real industry contacts to invite targets to fake video meetings. Because messages arrive from genuine accounts and can reference existing relationships, sender recognition alone provides limited protection.　　Google Mandiant independently documented a similar UNC1069 intrusion in February. A victim received messages from a compromised crypto executives Telegram account, scheduled a meeting and was redirected to a spoofed Zoom domain. The victim

Coldcard temporarily halts customer data deletion over July exploit

Coldcard has temporarily suspended its automatic customer data deletion process because of legal obligations tied to the security incident disclosed on July 30, preserving records that would otherwise have been erased after 120 days.　　SummaryColdcard has suspended its automatic customer data deletion policy because of legal obligations tied to its July security incident.Customers can still request their records be handled under the companys original data retention policy by contacting support.The policy change follows a wallet flaw that Galaxy Research linked to 1,596 confirmed stolen Bitcoin across three attack waves.Coldcard said retained customer records will remain restricted to authorized personnel and used only to meet legal requirements.　　Coldcard announced the policy change in a post on X, saying it must retain customer records that could be relevant to ongoing and anticipated legal proceedings arising from the wallet security incident.　　Update on Customer Data Retention　　We want to inform our customers of a change to our data-handling practices in connection with the security incident disclosed on July 30, 2026.　　As many of you know, our standard practice has been to automatically blank customer records after…　　— COLDCARD (@COLDCARDwallet) August 7, 2026　　The company said the temporary measure overrides its published data-retention schedule but added that customers who do not

Crypto crime has moved beyond online hacks, Chainalysis says

Chainalysis has warned that cryptocurrency crime has increasingly extended into kidnappings, home invasions and other violent incidents as criminals pursue holders who can transfer digital assets immediately under coercion.　　SummaryChainalysis said violent attacks against crypto holders have become more common as criminals target self custody wallets and instantly transferable assets.The report estimated more than $30 million has been stolen through successful physical attacks during the first half of 2026.Investigators found attackers leave blockchain trails that help trace stolen funds even after violent thefts succeed.France has recorded the highest number of publicly known crypto related violent incidents since 2023 as authorities expand organized crime investigations.Family members have increasingly been targeted to pressure crypto holders into transferring digital assets.　　According to the blockchain analytics firms latest report shared with crypto.news, cybercrime still accounts for most illicit crypto activity, including an estimated $3.4 billion stolen through hacks, $17 billion lost to scams and about $820 million linked to ransomware in 2025.　　At the same time, physical attacks have become more common because crypto holders often control large amounts of wealth through self-custody wallets without the institutional safeguards associated with traditional financial assets.　　The report estimates that violent criminals have extracted more than $30 million from crypto holders

Ripple News: XRP USD at Risk of Losing Key Support at $1

XRP trades near $1.03 as short positioning builds and spot demand weakens following news that the U.S. Senate delayed its CLARITY Act vote until September, which has had a negative effect on the Ripple chart.　　According to market data from CoinGecko, the token recorded a near -2% 24-hour decline, with an intraday range of $1.0153 to $1.039, keeping its market capitalization near $64.7Bn. Trading volume stands around $1.4Bn against a circulating supply of 62.53 billion tokens.　　Senate Majority Leader John Thune confirmed on August 7 that consideration of the CLARITY Act will resume after the August legislative recess. While the delay removes an immediate regulatory tailwind in the US, market participants are weighing this against Ripples reported full compliance in Crypto-Assets (MiCA) and Crypto Asset Service Provider (CASP) in Luxembourg.　　Can regulatory clearance in Europe offset deferred US legislative timelines？ Meanwhile, speculative chart projections circulating on social channels point toward targets at $7 and $27 by October 2026, though present market indicators reflect more realistic near-term consolidation.　　Can the XRP Price Hold Above $1 Amid Regulatory Delays？　　$XRP is at a two-year low.
