Absent from results = SM activity below threshold on that chain, not necessarily unsupported. Use --limit 200; --limit 100 silently drops mid-tier tokens. ETH+ & SOL− = rotating from SOL→ETH. One chain positive only = chain-specific play. 24h/7d divergence across chains is the rotation signal, not 1h.
