›How does the profit calculator work?
It buys with your investment at the buy price (minus the entry fee), then sells everything at the sell price (minus the exit fee). The result shows net profit or loss, ROI, the total you'd walk away with, and what fees took. Amounts are currency-agnostic, so enter everything in the same currency you think in.
›What does the market cap comparison show?
It answers the classic "what if X had Y's market cap" question. We divide the target coin's market cap by the subject coin's, then multiply the subject's live price by that ratio. It's a valuation thought experiment, not a prediction.
›Where do the live prices come from?
The same market data that powers the rest of Block Insider, refreshed every few minutes. The "use live price" shortcuts fill in the current USD market price of the selected coin.
›Is this financial advice?
No. Both tools are calculators over public market data. They don't account for slippage, spreads, taxes, or funding rates, and past prices never guarantee future ones.
