$81.5K feels like a key level for Bitcoin. Will it hold?

BITCOIN'S HASHRATE IS UP ABOUT 1,300X SINCE 2016 The network's 7-day average hashrate has risen from about 0.78 EH/s in January 2016 to about 1,007 EH/s today, or 1 zetahash per second, across three halvings. It's still just below the October 2025 peak of about 1,136 EH/s. Every jump in hashrate raises the hardware and energy an attacker would need to rewrite bitcoin's history.

🇩🇪 GERMANY’S LARGEST BANK TO LAUNCH BITCOIN CUSTODY SERVICE WITHIN WEEKS Deutsche Bank is preparing to launch its first institutional Bitcoin custody service within the next several weeks, according to comments from a senior executive published by Reuters. Gerald Podobnik, co-head of the bank’s corporate banking division, confirmed that the service will initially launch in Germany before expanding into major Asian financial centers in 2027. The platform will allow institutional and corporate clients to custody Bitcoin and other supported digital assets directly through Deutsche Bank. Unlike self-custody solutions, the bank will manage clients’ private keys using dedicated security hardware, segregated storage and multiple layers of transaction authorization. Deutsche Bank first announced the initiative in September, but has now confirmed that its launch is only weeks away, subject to the remaining regulatory process.

MSCI MOVES CLOSER TO EXCLUDING STRATEGY AND OTHER BITCOIN TREASURY COMPANIES FROM ITS GLOBAL EQUITY INDEXES MSCI is advancing a proposed methodology that could remove Michael Saylor’s Strategy ($MSTR), Japan’s Metaplanet, and other digital asset treasury companies from its Global Investable Market Indexes. The proposed framework would classify companies primarily engaged in accumulating financial assets as “non-operating,” making them ineligible for inclusion in major equity benchmarks. The potential consequences are significant: - JPMorgan estimates $2.8 billion in forced selling of MSTR shares by passive funds tracking MSCI indexes. - Broader outflows could reach $8.8 billion if other index providers adopt similar rules. - Strategy’s counter-analysis suggests MSCI-tracking funds hold approximately 3.1% of its outstanding shares. A final decision is expected around October 16, with implementation potentially beginning November 30.

MARK KARPELES CREATES PUBLIC DATABASE TRACKING COMPROMISED LEDGER DEVICES Mark Karpeles has launched a webpage documenting reported Ledger hardware implants, compiling cases he has reviewed and verified through publicly available reports and images shared on X. The database also allows users to submit new cases, helping track the potential scope of the ongoing Ledger supply chain security incident.

UK High Court: Chinese law governs claims to 61,000 bitcoin seized from Zhimin Qian. Justice Mark Turner found the fraud, the contracts, and the losses all happened in China, so English tracing cannot revive property rights lost under Chinese law. The coins are worth about $5 billion near $83,200. Ownership is still open. Fieldfisher is appealing. The CPS says a later hearing will test whether any victim can prove a proprietary interest.

OneKey has cut off reseller CryptoBilis and is offering free replacements after Ledger confirmed an unauthorized hardware implant in a device sold through that distributor. Blockchain investigator Specter put related losses above $86 million. Ledger has not confirmed the total, and says confirmed cases were limited to CryptoBilis stock, not its own channels. OneKey CEO Yishi Wang said none of its users have reported losses, but that "users' asset security can't rely on luck."

BREAKING: TREZOR TO TERMINATE RESELLER AUTHORIZATIONS AMID HARDWARE WALLET SUPPLY-CHAIN ATTACK CONCERNS Trezor is significantly reducing its authorized reseller network following the recent Ledger supply-chain attack.

FORMER CRYPTOBILIS OWNERS BREAK SILENCE ON LEDGER SUPPLY CHAIN ATTACK CryptoBilis co-founders Arravind Prabu and Vimalatheethan have issued an official statement distancing themselves from the company’s current operations following reports of compromised Ledger devices. According to the statement: • CryptoBilis was acquired by new ownership earlier this year. • Both founders stepped down and completed the operational handover in March 2026. • Neither has had access to customer databases, order histories, backend systems, or administrative accounts since the handover. • The acquisition agreement prohibited a joint public announcement until mid-October 2026, although suppliers had reportedly been informed of the ownership change. • Both founders offered to provide Ledger with historical information to assist its investigation. The statement identifies Nicholas Chang as the current person in charge of CryptoBilis. The revelations raise further questions about the reseller’s ownership transition and the timeline of the suspected Ledger supply chain attack.

THORCHAIN VAULTS AFTER HALTING TRADING Tether has reversed its decision to blacklist four THORChain USDT vaults on the Tron blockchain, approximately three hours after freezing $1.45 million in assets. The affected vaults reportedly held 93% of THORChain’s Tron-based USDT liquidity, forcing the protocol to suspend trading, transaction signing and liquidity-provider operations. THORChain co-founder Chad Barraford said the protocol received no warning or explanation from Tether before the freeze. The four addresses were subsequently removed from the blacklist, allowing Tron trading and related operations to resume. However, 19 other addresses reportedly blacklisted during the same operation remained frozen. The incident comes amid heightened scrutiny of Tether’s ability to freeze assets across decentralized financial infrastructure. THORChain facilitates native Bitcoin swaps without requiring users to wrap BTC or transfer custody to a centralized exchange. While THORChain’s validators collectively control its vaults, they cannot override restrictions imposed by centralized token issuers. The reason for Tether’s initial action remains unclear.

HARDWARE WALLET RESELLER CRYPTOBILIS SOLD TO CHINESE NATIONAL BEFORE SUSPECTED SUPPLY CHAIN ATTACK Newly surfaced corporate records indicate that Malaysian hardware wallet reseller CryptoBilis changed ownership, with an individual identified as Jiaming, whose registered address is in China’s Heilongjiang province, listed as holding 100% of the company’s shares as of August 3. The company’s former co-founder has now confirmed that CryptoBilis was acquired in March, when the original owners stepped down from all operational, managerial, and administrative roles. According to the statement, the founders have had no operational visibility since the handover, although they continued assisting with event coordination. “We are no longer part of the company,” the former co-founder stated, urging current management to resolve the situation transparently. The revelation comes amid an investigation into a suspected Ledger hardware wallet supply chain attack involving devices modified with hidden implants capable of stealing seed phrases. There is currently no confirmed evidence linking CryptoBilis’ ownership change to the suspected wallet compromises. h/t cryptoian and Bored2AI
