Frequently Asked Questions
How is the projected price calculated?
Projected Price = Target Market Cap / Circulating Supply of Coin A. For example, if SOL (480M supply) reached BTC's $2T market cap: $2T / 480M = $4,167 per SOL.
Why does circulating supply matter more than total supply?
Market cap is always calculated using circulating supply (coins actually in the market), not total or max supply.
Where does the data come from?
Live data is fetched from CoinGecko's free public API. If unavailable, the tool falls back to approximate offline data.
