## About
CryptoBook answers questions of the form "What would X be worth at Y's market cap?" by pulling live price and circulating-supply data, then solving for the per-token price needed for coin A to match coin B's total valuation. Results are a thought experiment, not financial advice. Data refreshes every 60 seconds.

## Canonical URL shape
