Market cap what-if
“This coin is only $0.20, it could easily reach $100” is an argument about unit price. Unit price is a function of supply, and this shows what the claim actually requires.
This is arithmetic, not a forecast
The calculation is target market cap ÷ this coin’s circulating supply. It says what the price would have to be at a given valuation. It says nothing whatsoever about whether that valuation is plausible, and this site publishes no price predictions.
Why the answers are usually deflating
That is the point. An asset with tens of billions of units in circulation cannot reach the unit price of one with twenty-one million, because getting there would require a market capitalisation larger than the entire asset class. The unit price looks cheap; the valuation it implies does not.
What this does not model
Supply is not fixed. Tokens unlock, get minted, or get burned, and a supply that grows pushes the required price down further. The figure uses circulating supply as sourced now, not fully diluted supply — which for many tokens is considerably larger.
