[Staking ranking] Top 10 slide as one-year returns diverge

Staking market capitalization declined across the top 10 assets, led by Sui's 12.4% weekly drop. One-year total returns ranged from 98.79% for Hyperliquid to -67.34% for Cardano, showing wide divergence among staking assets. The slide reflects broader market weakness, with most top staking tokens losing value over the past week.
