Miners Bounced Harder Than Bitcoin
Riot, Clsk, and Mara rose together on October 27 and 28. Bitcoin's rise on October 27 was only about 1%. The pattern fits relief after a sharp sector selloff, with AI-infrastructure stocks recovering after Anthropic's IPO filing. No single catalyst has been verified for all three miners. A two-day rebound does not settle miners' operating costs or AI-project financing.
