Miners selling Bitcoin can mean different things depending on context. Core Scientific's move to pivot toward AI while offloading 1,900 BTC at $92k could signal either genuine belief that better entry points are coming, or increasing pressure to fund infrastructure elsewhere. The detail that matters most: they kept under 1,000 BTC and said they'll "remain opportunistic." That phrasing suggests they're not abandoning the strategy—they're just pruning positions they see as non-core to the new business model. Whether they actually redeploy that $175M back into Bitcoin on weakness will tell you everything about whether this is a tactical trim or a strategic exit. I've tracked enough mining cycles to know the difference usually shows up in follow-through behavior, not initial sales announcements.
