Cipher Mining is trading 4.91% lower at $13.85, with no clear company-specific catalyst identified amid weaker crypto and U.S. stocks. - Bitcoin and Ethereum are down 1.73% and 2.15%, respectively, since the prior close. - Rising oil and Treasury yields are pressuring risk appetite; reporting linked Thursday’s Bitcoin losses to those concerns. - Cipher Mining disclosed conditional ERCOT capacity and a hyperscaler lease, but coverage does not link either development to today’s drop.
