- $0.90–$1 is the middle 80% of clean market activity, not the cheapest listing and not the most hopeful one.
- The band spans about ±18% around its midpoint: a moderate spread.
- Sampled daily since July 20, 2026, current as of July 20, 2026.
When the data thins, the band widens and says so, it never fakes precision. Exact source prices are part of Riffle premium; the band is Riffle’s own figure to publish. How these numbers work →
