BullHow it works
Market cap is the price of a coin times the number of coins in circulation. If we keep the circulating supply of coin A the same and give it the market cap of coin B, we can work out the price coin A would need.
Formula
Example
Imagine coin A has 50 billion coins in circulation and coin B has a market cap of 1 trillion dollars. Coin A would need a price of 1,000,000,000,000 / 50,000,000,000 = $20 to match coin B. The calculator above does the same with live numbers.
Why supply matters more than price
A coin priced at a fraction of a cent is not automatically cheap. If it has trillions of coins in circulation, even a small price rise means a huge market cap. Comparing market caps is a more honest way to judge how much room a coin has to grow.
Limits of this comparison
- Circulating supply can change as new coins unlock or get burned.
- Reaching another coin's market cap needs a huge amount of new money and is never guaranteed.
- This is a what-if tool, not a price prediction.
Frequently asked questions
Is this a price prediction?
No. It only shows the math of what the price would be at a different market cap.
Which supply do you use?
Circulating supply from CoinGecko, not max or total supply.
Can I compare any coins?
You can compare any two of the 250 largest coins by market cap.
