This site will not tell you to buy or sell anything. What the rainbow chart can tell you is where today's price stands relative to Zcash's own history: right now, $1190.12 sits in the Is this a bubble? band.
What it cannot tell you: whether privacy coins gain or lose regulatory ground, whether shielded adoption grows, or whether the 2025-2026 repricing holds. A regression knows the past. Position sizing, time horizon and risk are yours. Not financial advice.
