How it works

Market cap is price multiplied by outstanding supply. For crypto that's circulating supply from CoinGecko. For stocks it's shares outstanding pulled from Finnhub's company profile endpoint.

The "What if" tool swaps in a hypothetical price and recomputes the cap against today's supply, so you can see how much additional (or less) total value a move would imply. Numbers here are for reference and education — not investment advice.
