Coinglass data cited by ChainCatcher shows that a BTC break above $84,288 would liquidate roughly $1.149 billion in short positions across major centralized exchanges. A slide below $76,818 would instead wipe out about $1.108 billion in long positions.

Bitcoin miners moving into AI extended losses this month. Riot Platforms fell to $12.53, 60% below its yearly peak, cutting valuation to $4.7 billion from $10.8 billion. MARA dropped to $7, down 57% year to date. Core Scientific slid to $13.10 from a $30 peak. Gartner warned neocloud firms could book major impairments by late 2030, while MARA short interest sits at 26%.

Bitcoin miners pivoting into artificial intelligence, among them Riot Platforms, MARA Holdings, IREN and Core Scientific, have sold off this month as fears of an AI bubble build. Riot fell to $12.53, its lowest since April and 60% below this year's high, shrinking its valuation from more than $10.8 billion to $4.7 billion. MARA dropped to $7, a February low and 57% below its year-to-date peak. Core Scientific slipped to $13.10 from a year-to-date peak of $30. IREN has drawn heavy selling as well. Losses deepened across other neocloud names, including CoreWeave, Nebius and TeraWulf, as anxiety over the AI industry intensified. The AI Stock Bubble Index has climbed to an elevated 74. The shares extended this month's declines after Gartner warned that neocloud operators will have to disclose substantial impairments in late 2030, pointing to a wide shortfall between expected revenue and costs. Debt-funded AI expansion also leaves the group exposed to elevated credit risk. A VanEck report published earlier this year estimated a $50 billion funding gap for bitcoin miners moving into AI, a hole likely to widen as memory, GPU and server costs rise. CoreWeave, the largest company in the sector, now pays a 15% yield on its key 2031 bond. Investors have resisted efforts by Nvidia-backed Nscale and Firmus to reach public markets: Firmus withdrew its initial public offering, and Nscale shareholders want the company valued at about $15 billion. Competition is likely to weigh on results over time. SpaceX has emerged as a major rival, signing significant agreements with Alphabet, Anthropic and Reflection AI. Meta Platforms, another large neocloud customer, is weighing a move into the industry by renting out spare computing capacity. Those risks explain the crowded short positioning in the sector: IREN at 20.7%, Core Scientific at 20.54%, Riot at 12.5% and MARA at 26%.

Keystone has confirmed a customer data breach at its hardware wallet operation, saying hackers gained unauthorized access to its website and exposed customer names, contact information, shipping addresses and order details. The company detected the intrusion on Oct. 20 and confirmed the exposure on Oct. 23 after reviewing Shopify API activity. Payment information, recovery phrases, private keys and wallet passwords were not compromised, Keystone said. It warned that affected customers could be targeted by phishing scams built around fake refunds, replacement devices or order issues. Keystone said it has blocked the unauthorized access, patched the vulnerability and launched an investigation. "We owe you an apology," the company said. "On October 20, we detected unauthorized access to our official website. After verifying API activity with Shopify, we confirmed on October 23 that a third party obtained customer shipping information. You trusted us with those details, and we're sorry."
