Daily brief: Musk AI debt warning, Electrum wallet bug, UK bank complaints

CoinDesk's daily briefing rounds up three developments. Elon Musk warned that AI debt markets are drying up for companies without substantial outside revenue, escalating his neocloud shakeout prediction. Electrum, one of Bitcoin's oldest software wallets, disclosed a vulnerability that let malicious servers trick users into signing payments to attackers via fake Replace-by-Fee fee bumps, fixed in 4.8.3 released Oct. 24.

• Britain's major banks have received nearly 10,000 complaints over three months about restrictions on cryptocurrency purchases, undercutting the UK's ambitions as a crypto hub.
• The Musk warning deepens the AI-jitters narrative behind the recent neocloud sell-off.

No additional details were disclosed in the briefing.
