Crypto Market Cap Calculator
“If DOGE had Bitcoin's market cap…” — settle it with numbers. Pick any two coins to see what one would cost with the other's market cap and how many multiples away that is, or work out market cap from price and supply. Live prices, editable everything, no sign-up.
≈ snapshot, 2026-07 — override any time.

Pick two coins (or fill in price and circulating supply manually) to see what the first would be worth with the second's market cap.
Market caps are estimated as live price × circulating supply from our 2026-07 snapshot. Supplies drift slowly for the majors, and every field above is editable — paste exact numbers for exact results.
How to read the result
- Implied price — the second coin's market cap ÷ the first coin's circulating supply. What one coin would cost at that valuation.
- The multiple — how many times today's price would have to grow (or shrink) to get there. This is the number that separates plausible from fantasy.
- Estimated market caps — live price × snapshot supply for both coins, so you can see the gap you're bridging.
A coin needing a 3× to match a rival is a market-cycle story; a coin needing a 900× is a lottery ticket. Neither is a prediction — but if you have a view on the direction, put it on record and let your accuracy speak.
Frequently asked questions
How is crypto market cap calculated?
Market cap = current price × circulating supply. If a coin trades at $2 and 10 billion coins are in circulation, its market cap is $20 billion. It's the standard way to compare the total size of two cryptocurrencies, because price alone says nothing without the supply behind it.
What does “X with the market cap of Y” mean?
It's a thought experiment: if coin X's total valuation grew to match coin Y's, what would one X cost? The calculator divides Y's market cap by X's circulating supply. It's useful for gut-checking hype — seeing that a small coin would need to 500× to reach Bitcoin's market cap tells you how realistic 'the next Bitcoin' claims are.
Why does a low coin price not mean a coin is cheap?
Because supply varies wildly. A $0.00002 coin with 500 trillion tokens in circulation is a bigger project by valuation than a $50 coin with 10 million tokens. Market cap normalizes for supply, which is exactly why this calculator works in market caps rather than raw prices.
Where does the circulating supply data come from?
Prices are live from BitPredict's price feed; circulating supplies come from a curated snapshot (currently 2026-07) covering the major assets. Supplies of large caps drift slowly, and both fields are editable — paste the latest supply from any tracker for exact numbers.
Can a coin really reach another coin's market cap?
History says it's rare above the top ten. Overtaking a major requires tens or hundreds of billions of dollars of net new inflows, not just enthusiasm. The multiple this calculator shows is a good reality filter: 3–5× happens in bull markets; 500× almost never does at scale.
