We're talking serious outperformance across the entire altcoin space—the kind of momentum shift that catches most traders off-guard. A breakout at this level wouldn't just be another bounce. It'd signal the end of a prolonged consolidation phase. That's typically when altcoins tend to run hard and make up for lost ground against Bitcoin.
