Module 1: Introduction to Crypto Markets
Market Cap, Supply, and Why Price Alone Means Nothing
Chapter 10 of 15 · about 6 minutes
10.1 The "cheap" token
Mint found a token trading at $0.002. "Bitcoin is expensive, but this is basically free," Mint said. "If it just gets to $1, I'd make 500 times my money. That's not crazy, right? It's only one dollar."
Hash pulled up a chair. "This is the single most common mistake new crypto investors make. The price of a token, on its own, tells you almost nothing. Let me show you why."
10.2 Market capitalisation
The number that matters more than price is market capitalisation, or market cap. It's the total value of all the tokens currently in circulation.
Market cap = price × circulating supply
Think of a pizza. The price of one slice depends on how many slices the pizza is cut into. A pizza cut into 8 slices has expensive slices. The same pizza cut into 8,000 slices has very cheap slices. But it's the same pizza. Market cap is the price of the whole pizza.
Let's compare two tokens.
| Token A | Token B | |
|---|---|---|
| Price | $0.01 | $100 |
| Circulating supply | 100,000,000,000 | 1,000,000 |
| Market cap | $1,000,000,000 | $100,000,000 |
Token A has a much lower price, but its market cap is ten times larger than Token B's. Token A isn't "cheap." It's a $1 billion asset sliced into a huge number of tiny pieces.
10.3 Back to Mint's dream
Now let's revisit Mint's token. Suppose it has 500 billion tokens in circulation.
At $0.002, market cap = $0.002 × 500,000,000,000 = $1 billion.
At $1, market cap = $1 × 500,000,000,000 = $500 billion.
To reach $1, the token would need to be worth roughly as much as some of the largest assets in crypto, which took years and enormous adoption to reach that size. "It's only one dollar" was really "it needs to become one of the most valuable crypto assets in the world."
"Okay," said Mint. "That's very different."
Whenever you imagine a price target, convert it into a market cap and ask whether that number is realistic. This one habit will protect you from a lot of bad decisions.
10.4 The three supply numbers
Supply sounds simple, but crypto data sites typically show three different numbers, and the gaps between them matter.
Circulating supply is the number of tokens currently available and trading in the market.
Total supply is the number of tokens that exist right now, including those locked or reserved and not yet circulating.
Max supply is the maximum number of tokens that will ever exist, if there is a cap. Bitcoin's max supply is 21 million. Some tokens, like ETH, have no fixed max supply.
10.5 Fully diluted valuation
If market cap is the value of tokens circulating today, fully diluted valuation (FDV) is what the project would be worth if every token that will ever exist were circulating at today's price.
FDV = price × max supply (or total supply, if there's no max)
Here's why it matters.
| Token C | |
|---|---|
| Price | $2 |
| Circulating supply | 100,000,000 |
| Max supply | 1,000,000,000 |
| Market cap | $200,000,000 |
| FDV | $2,000,000,000 |
| Share of supply circulating | 10% |
Only 10% of Token C's tokens are circulating. The other 90% will enter the market over time, mostly through unlocks to the team, early investors, and the project treasury, as we discussed in Chapter 9.
Suppose another 100 million tokens unlock next month. Circulating supply doubles. For the price to stay at $2, demand for the token would also need to double. If it doesn't, the price will likely fall to absorb the new supply.
"So a low market cap with a high FDV," said Node, "means lots of future selling pressure."
"Potentially," said Hash. "It depends on who gets the new tokens and whether they sell. But a big gap between market cap and FDV is always worth investigating."
10.6 Inflation and deflation in tokens
Just like fiat currencies from Chapter 1, tokens can have inflation: new supply being created over time. Some tokens issue new supply to stakers or validators. Others have unlock schedules. Some destroy, or burn, tokens to reduce supply, like the fee burn on Ethereum mentioned in Chapter 4.
When evaluating a token, ask how supply will change over the next one to three years. A token whose supply grows 30% a year needs a lot of new demand just to keep its price flat.
10.7 Market cap isn't money in the market
One more trap. Market cap is a calculation, not a pile of money. It assumes every token is worth the latest traded price. In reality, if many holders tried to sell at once, the price would fall sharply, because there wouldn't be enough buyers.
This is why liquidity and trading volume matter alongside market cap. A token with a $500 million market cap but only $200,000 of daily trading volume is very fragile. A large holder trying to sell could crash the price. This is especially common with tokens where a small number of wallets hold most of the supply.
| Signal | What it suggests |
|---|---|
| Large gap between market cap and FDV | Lots of future supply coming, possible selling pressure |
| Very low daily volume compared to market cap | Thin liquidity, prices can move violently |
| A few wallets holding most of the supply | Concentration risk, a single seller can crash the price |
| High annual supply growth | Price needs strong new demand just to stay flat |
10.8 Comparing across crypto
Market cap is also how the crypto market ranks assets. Data sites list tokens by market cap, and "total crypto market cap" is the combined value of all of them.
A related measure is dominance, the share of the total crypto market cap held by a single asset. Bitcoin dominance is closely watched. When it rises, money is generally concentrating in Bitcoin. When it falls, money is flowing into other assets, often in more speculative phases of the market.
10.9 Try it yourself
Pick three tokens from any crypto data site: one with a price above $1,000, one between $1 and $100, and one below $0.01. For each, write down the price, circulating supply, max supply, market cap, and FDV. Rank them by price, then by market cap. Notice how different the two rankings are.
Then, for the token with the biggest gap between market cap and FDV, find its unlock schedule and identify the next major unlock.
Key takeaways from this chapter
- Price alone means nothing. Market cap, which is price times circulating supply, shows a token's actual size.
- A low price doesn't mean a token is cheap. Always convert price targets into market caps to check whether they're realistic.
- Circulating, total, and max supply are different, and the gaps between them matter.
- Fully diluted valuation shows what a project is worth if all tokens were circulating. A large gap between market cap and FDV signals future supply.
- Token supply can inflate or deflate over time through issuance, unlocks, and burns.
- Market cap isn't real money. Low volume, thin liquidity, and concentrated ownership make a token fragile.
