Market Cap Comparison Tool
See what one coin’s unit price would be if it reached the market capitalization of another.
Key insight
Total supply versus circulating supply can change the implied price dramatically. Always check both figures before running a comparison — tokens with large locked supplies can have a circulating market cap that dramatically understates dilution pressure.

What the Market Cap Comparison Tool does
The Market Cap Comparison Tool answers a specific speculative question: If Coin A reached the market capitalisation of Coin B, what price would Coin A trade at? You select two assets and the tool does the arithmetic — dividing Coin B’s total market cap by Coin A’s circulating supply to produce the implied price.
This is sometimes called a “what-if” valuation. It does not predict anything; it makes an assumption explicit. If you believe Coin A will eventually be as large as Coin B, this is what a share of Coin A would be worth. The merit of that belief is entirely yours to judge — and that is where most of the analytic work actually lives.
The formula
Market cap = Price × Circulating supply
Why market cap matters more than price per token
A token trading at $0.001 sounds “cheap”. A token at $50,000 sounds “expensive”. Neither observation is analytically meaningful without knowing the supply. Market capitalisation — price multiplied by circulating supply — is the only comparable measure of relative size.
Four tokens with wildly different unit prices can share identical market caps. The comparison tool forces supply into the analysis so you can reason about scale rather than just price.
Worked example: comparing an altcoin to Ethereum
Illustrative — market caps change daily
Suppose Ethereum has a market cap of $400 billion and an altcoin has a circulating supply of 1 billion tokens with a current price of $2 (market cap: $2 billion).
- Implied price at ETH market cap: $400B ÷ 1B = $400 per token
- Upside multiple: $400 ÷ $2 = 200×
This calculation is easy to make and seductive to believe. The hard part is the premise: will this altcoin ever reach Ethereum’s market cap? That requires Ethereum’s developer ecosystem, on-chain activity, liquidity, institutional trust and years of accumulated network effects — not just a favourable arithmetic comparison.
Worked example: the “flippening” scenario
What if ETH overtook BTC?
Suppose Bitcoin has a market cap of $1.3 trillion and Ethereum’s circulating supply is approximately 120 million ETH.
- Implied ETH price at BTC market cap: $1.3T ÷ 120M = ~$10,833 per ETH
The Flippening is the hypothetical moment when Ethereum overtakes Bitcoin by market capitalisation. The Market Cap Comparison Tool makes this question precise and answerable — though not predictable. It separates the arithmetic (“what price would ETH be at parity?”) from the analysis (“why would it get there, and when?”).
Scenario: three Layer-1 protocols at the same market cap
Within one sector, three protocols might have similar adoption profiles but very different token prices due to supply differences. The comparison tool reveals which is “cheapest” by market cap.
| Protocol | Token price | Supply | Market cap | Implied price at $1.3T BTC cap |
|---|---|---|---|---|
| Chain A | $500 | 10M tokens | $5B | $130,000 |
| Chain B | $2 | 2.5B tokens | $5B | $520 |
| Chain C | $0.05 | 100B tokens | $5B | $13 |
All three chains have the same current market cap ($5B). An investor who buys Chain C at $0.05 hoping for a $13 price is making the same market-cap assumption as an investor buying Chain A at $500 hoping for $130,000. Unit price tells you nothing; market cap tells you the shared starting point.

Circulating supply vs total supply vs FDV
The tool uses circulating supply — the tokens in the market today. Two other supply figures matter for a complete analysis:
- Total supply: all tokens that exist, including locked, vested or reserved coins not yet circulating.
- Fully diluted valuation (FDV): what the market cap would be if every token that will ever exist were circulating today at the current price.
Why FDV changes the picture
A token has 200 million circulating supply (market cap at $5: $1B). Its total supply is 2 billion — 90% not yet released. FDV at $5 = $10B. A comparison against Ethereum ($400B) using circulating supply implies 400× upside. Using FDV basis, the same comparison implies only 40× upside — because the denominator in the market-cap comparison is ten times larger once all tokens are counted. Many retail investors see the circulating-supply price target without checking how much supply dilution is coming.
The total crypto market as a reference
| Comparison asset | Approx. market cap (2024) | Notes |
|---|---|---|
| Bitcoin (BTC) | ~$1.3 trillion | Largest single crypto asset |
| Ethereum (ETH) | ~$400 billion | Largest smart contract platform |
| Gold (total market) | ~$14 trillion | Most common cross-asset benchmark |
| Silver (total market) | ~$1.4 trillion | Comparable scale to BTC |
| Apple (AAPL) | ~$3 trillion | Largest public company by cap |
| S&P 500 (total) | ~$44 trillion | Entire US large-cap equity market |
How to use the tool
- Select Coin A — the coin whose implied price you want to calculate.
- Select Coin B — the reference whose market cap you are projecting onto Coin A.
- The tool instantly shows the implied price of Coin A if it had Coin B’s current market cap, using Coin A’s live circulating supply.
- Ask the harder question: is this comparison between similar types of projects? Does Coin A have the network effects, liquidity and adoption to realistically reach that scale?
- Check the FDV: multiply the implied price by total supply to see whether the fully-diluted market cap at that price is even more extreme than the comparison suggests.
Common mistakes to avoid
- Treating the output as a price target. The result is arithmetic, not analysis. It is only valid if the premise (equal market cap) is realistic for these two specific assets in their current form.
- Ignoring total supply vs circulating supply. Many coins have significant locked, vested or yet-to-be-minted supply. Always check the FDV before forming a view based on the circulating-supply comparison.
- Cross-sector comparisons without context. Comparing a DeFi governance token to Bitcoin is not obviously meaningful: they serve different purposes, attract different investors and carry different risk profiles.
- Assuming the comparison coin is “the ceiling”. The comparison just provides an anchor. There is no rule that says an altcoin cannot eventually exceed Ethereum’s market cap — or that it will get anywhere near it.
Common questions
What is the difference between market cap and FDV? Market cap uses only coins currently circulating. FDV uses the total maximum supply. For tokens with large scheduled unlocks, FDV can be many times the current market cap.
Can I compare crypto to gold? Divide gold’s approximate total market cap by the coin’s circulating supply manually using the formula above. The tool compares two crypto assets directly; cross-asset comparisons use the same formula but require manual input of the non-crypto market cap.
Why do some tokens have much higher total supply than circulating supply? Projects often lock a portion of tokens for founders, investors, ecosystem funds or future issuance. These unlock gradually under a “vesting” schedule, creating sell pressure over time and diluting existing holders’ percentage of supply.
Is a lower market cap always “more upside”? Not necessarily. Smaller market caps can reflect less liquidity, weaker technology, smaller communities or higher risk of project failure. A low market cap can mean a larger potential move — but also a higher probability of going to zero.

In practice
What price if this Layer-2 token reached Ethereum's scale? Benchmarking a speculative thesis
A popular framing in crypto research is "what would Token X be worth if it reached the market cap of Ethereum?" This is easy to sensationalise. The Market Cap Comparison Tool makes the arithmetic transparent — and the assumptions explicit.
A hypothetical Layer-2 token: 800 million tokens in circulation, current price $0.80 (market cap: $640 million). Ethereum's market cap: approximately $400 billion. Running the comparison: $400B ÷ 800M = $500 per token — a 625× increase from $0.80. The tool surfaces this instantly. The harder question — whether an L2 token will ever capture Ethereum-level adoption — is not in the calculator. It is in the analyst's research into developer activity, total value locked, fee revenue and competitive moat. The tool's value is making the assumption explicit so the reader can judge it, rather than burying it in optimistic prose.
Key takeaway: Always follow the market-cap comparison with the supply question: does the total supply include large locked allocations that will hit the market later? The fully diluted valuation (FDV) is often 5–10× the current market cap for newer tokens.
