What is market capitalization?
Lesson 05 · practical guide
Market capitalisation is a size measure: price multiplied by shares or tokens considered in circulation. It helps compare assets, but it is not cash in the project, intrinsic value, liquidity or the amount you could sell without moving the market.
What you will learn
Use market capitalisation correctly as a size measure rather than a shortcut for value.
Key terms
- Market capitalisation — price multiplied by the relevant number of units.
- Fully diluted value — price multiplied by a project’s possible total supply.
- Float — shares or tokens actually available for public trading.
Follow these steps
- Write the exact price and the supply measure used in the calculation.
- Check whether locked, treasury or future units could increase supply.
- Compare market cap with revenue, cash flow, network usage or other relevant fundamentals.
- Never infer that a low unit price means an asset is cheap.
Practical advice
A €0.01 token with 100 billion units can be larger than a €100 token with one million units. Always calculate the size of the whole claim, then study what supports that size.

What market capitalisation can and cannot tell you
Market capitalisation is a multiplication, not a valuation model. It estimates the market value of the relevant shares or tokens at the current quoted price. It is helpful for comparing broad size, but it does not tell you how much cash exists, how much money could be withdrawn, or whether the price is justified by future results.
Crypto comparisons require extra care because different sites may use circulating supply, total supply or fully diluted supply. Locked allocations, vesting schedules and treasury balances can change the amount available to trade. A low unit price is not evidence of cheapness; the number of units matters just as much.
Use size as a starting point for research
After calculating market capitalisation, inspect liquidity, volume quality, ownership concentration and future issuance. A large asset may still be risky, while a small asset may have room to grow but be difficult to exit. Look for the gap between the displayed price and the price available for a realistic order size.
For a valuation decision, move beyond size. Study cash flows for a company or usage, fees and incentives for a protocol. Write down what would need to happen for the current value to make sense, then compare that story with evidence rather than with the unit price.
What usually goes wrong
The most damaging misunderstanding is reading market capitalisation as money that has been invested, or as money available to be withdrawn. It is a multiplication: the last traded price times a supply figure. If a thin market sets that price, the number is far larger than what anyone could actually realise by selling. The second error is comparing size across assets without checking how supply was counted. Circulating supply, total supply and fully diluted valuation can differ enormously, and a project choosing the flattering measure is not doing anything unusual.
Beginners also fall for the low unit price. A token at a fraction of a cent feels cheap next to one priced in the hundreds, but unit price alone means nothing; only the size of the whole claim does. A project can issue a hundred billion units precisely so the price looks approachable. The final mistake is stopping at size. Market capitalisation is a starting question, not a verdict: it tells you which bracket something sits in, then you still have to explain why the market is placing it there and what would change that.
How it works
For stocks, market cap normally uses shares outstanding. Crypto websites may use circulating supply that excludes locked or vested tokens. Fully diluted valuation applies today’s price to a larger possible supply and can reveal future dilution.
A low market cap can grow quickly, but it can also be easier to manipulate and harder to exit. Check unlocks, treasury wallets, holder concentration and whether the displayed price comes from reliable markets.
Worked example
Numbers make an idea concrete. Here is a small, illustrative one — not a forecast.
Token A at €0.10 with 1 billion circulating tokens has a €100 million market cap. Token B at €10 with 5 million tokens has a €50 million market cap. Unit price alone says little.
Before you act
Run through these questions before you commit any money or make a decision based on this lesson:
- Which supply number is being used?
- How many units can be issued later?
- Who owns the largest balances?
- Could I exit near the displayed quote?
Practice this lesson
Reading is a start; doing the exercise is what makes the idea stick.
Calculate the market cap of three assets and compare their circulating supply, fully diluted value, unlocks and trading volume.
