Greenland's rare earth deposits just became the hottest geopolitical chess piece. While the national security angle dominates headlines, the real story? Those untapped reserves—36 to 42 million tonnes sitting beneath the ice, potentially making it the world's second-largest deposit after China. Scale that against what's actually driving demand: EV batteries need rare earths, AI chips can't function without them, defense infrastructure depends on consistent supply chains. Right now, China controls roughly 60% of global rare earth processing, creating massive leverage. Whoever secures steady access to high-grade deposits reshapes the entire tech supply chain. For the crypto and blockchain sectors? This matters more than most realize. Mining operations, chip production for validators, infrastructure build-out—all hinge on stable, affordable rare earth availability. When geopolitical powers start jockeying for resource control like this, downstream markets always feel the tremors.
