Market Cap vs Price: Why a Cheap Coin Is Not Always Cheap

Why a low price does not mean cheap

The price of one coin depends on two things: what the market values the whole project at, and how many pieces that value is split into. A pizza cut into eighty slices is not cheaper than the same pizza cut into eight. Each slice is just smaller.

Projects choose their supply when they launch. Some create a few million units, others create hundreds of billions. A project with a huge supply will almost always have a tiny unit price, even if the market values it highly. Comparing the prices of two coins on their own is like comparing one slice from two different pizzas without knowing how big either pizza is.

Market cap: price times circulating supply

Market capitalization, or market cap, is the total value the market currently puts on the coins in circulation. The formula is simple: market cap = price × circulating supply.

Here is a hypothetical example with made-up numbers. Coin A trades at $0.01 and has 500 billion coins in circulation. Its market cap is $0.01 × 500,000,000,000 = $5 billion. Coin B trades at $50 and has 20 million coins in circulation. Its market cap is $50 × 20,000,000 = $1 billion.

Coin A's price is 5,000 times lower, yet the market values it five times higher than Coin B. For Coin A to reach $1 with the same supply, its market cap would need to grow to $500 billion. Asking whether that is realistic is far more useful than noticing that the price looks small.

Circulating, total and maximum supply

Supply figures come in three common versions, and data sites do not always define them in exactly the same way.

• Circulating supply: coins that exist and can be traded now. This is the number used in the usual market cap figure.
• Total supply: coins created so far, including ones that are locked, held in reserve or not yet released, usually minus any that have been permanently destroyed (burned).
• Maximum supply: the hard limit on how many coins can ever exist, if the project has one. Bitcoin's rules cap it at 21 million coins. Many other assets have no fixed maximum, and new units keep being issued.

When circulating supply is much smaller than total or maximum supply, a lot of new coins may still reach the market. That matters for anyone holding the coin today.

Fully diluted valuation and token unlocks

Fully diluted valuation (FDV) asks what the project would be worth at today's price if every coin that can ever exist were already in circulation. It is usually calculated as price × maximum supply, or price × total supply when there is no maximum.

Take another hypothetical. Coin C trades at $2 with 100 million coins circulating and a maximum supply of 1 billion. Its market cap is $200 million, but its FDV is $2 billion. Only 10% of its coins are in circulation.

The other 90% is often held by the team, early investors or a project treasury, and released over time on a schedule. Each scheduled release is called a token unlock. If Coin C unlocked another 50 million coins in one month, its circulating supply would rise by half. If demand does not grow at the same pace, more coins competing for the same buyers can push the price down. Many projects publish their unlock schedules in their documentation, so it is worth checking before you buy.

Volume and liquidity

Market cap tells you about size, not about how easy a coin is to trade. Trading volume is the value of a coin bought and sold over a period, usually 24 hours. Liquidity describes how much you can buy or sell without moving the price much. It depends on how many buy and sell orders are waiting near the current price.

A coin can show a large market cap while very few orders sit in its order book. Then even a modest sale can push the price down sharply, and the market cap may overstate what holders could actually receive if many of them sold at once. Volume figures can also be inflated on some platforms through fake trading, so do not rely on a single source.

A quick checklist before comparing coins

• Is the circulating supply close to the maximum supply, or far from it?
• How large is the gap between market cap and FDV?
• Are big token unlocks scheduled in the coming months?
• Is trading volume steady across several well-known exchanges?
• Would your order be small compared with the orders already on the book?

None of these checks tells you whether a coin will rise or fall. They help you understand what you are looking at and the risks you are taking on.
