How to read market cap without fooling yourself
Market cap is the most quoted crypto number and the most misunderstood. Here's what it does and doesn't tell you.

Market capitalization is simple arithmetic: price multiplied by circulating supply. It is a rough measure of how much the market values a network — and it hides at least as much as it reveals.
The formula
If a token trades at $2 and 100 million are in circulation, the market cap is $200 million. That does not mean $200 million is sitting in the asset. It means the last trade, multiplied across every coin, would total that figure — if you could sell them all at that price, which you cannot.
Circulating vs. fully diluted
- Circulating supply counts coins available now.
- Fully diluted valuation assumes every coin that will ever exist is already trading. A big gap between the two is a warning about future selling pressure.
A low price is not "cheap." A $0.01 coin with a trillion-token supply is larger than a $50,000 coin with a few million.
What market cap can't tell you
It says nothing about liquidity, revenue, or how concentrated ownership is. A network can carry a large cap on thin volume, which means the number is fragile. Always read it next to daily volume and holder distribution.
