April's top altcoin gainers: $SKY leads with +549%, $LUNC and $SIREN both doubled.

April delivered outsized moves across a handful of altcoins, with SKY topping the leaderboard at +549.3% to $0.385. SIREN and LUNC followed with gains of +125.3% and +104.6% respectively, while EDGE posted a near-double at +96.2%.

Further down the list, PENGU, JST, DEXE, and ZEC each added between 39% and 53% — a broad-based rally across small and mid-cap assets. The spread of winners across unrelated sectors suggests the month's gains were driven more by rotating speculative appetite than any single narrative.
