Today's crypto prices by market cap
What is market cap in crypto?
Dogecoin costs pennies. Bitcoin costs tens of thousands of dollars. So which one is the bargain?
Neither, necessarily. The price of one coin says almost nothing about how big the whole thing is, and that single mix-up sits behind a lot of bad crypto decisions.
The formula, and what it measures
Market cap multiplies the price by the coins in circulation. A coin at $2.00 with 500 million in circulation is valued at $1.0 billion.
Price alone tells you very little. A coin at $0.01 can be worth more in total than a coin at $500, because it may have billions more coins in circulation. Market cap measures the whole thing, not one unit of it.
That's why KryptoKap ranks every coin by market cap. It's the usual way to compare a meme coin with Bitcoin on equal terms.
Market cap moves for two reasons. Either the price changes, or the circulating supply changes as new coins are released.
A worked example
Coin A trades at $0.50 with 40 billion coins in circulation, a $20 billion market cap. Coin B trades at $400 with 10 million coins, a $4 billion market cap.
Coin A has the lower price but is five times bigger. For coin A to reach $5, its market cap would need to hit $200 billion, which would put it near the very top of the market.
What market cap can't tell you
Market cap is a snapshot of the last trade multiplied by supply. It doesn't say how much money is actually behind a coin, how easy it is to sell, or whether the supply figure is reliable.
Two coins with the same market cap can be very different. One might have deep, steady trading and a fixed supply, while the other has thin trading and a large unlock coming. Check volume, liquidity and fully diluted value alongside it.
Sanity-checking a price target
Multiply any price target by circulating supply. For this 5 billion coin supply, a jump from $0.20 to $10 means growing from $1 billion to $50 billion.
Any price target can be tested in a few seconds. Multiply the target price by the circulating supply, and you get the market cap the target implies. Then ask whether that size is believable for this project.
Take a coin trading at $0.20 with 5 billion coins in circulation. Today it's worth $1 billion. At $1 it would be worth $5 billion, at $5 it would be worth $25 billion, and a $10 target means a $50 billion market cap, 50 times today's size. A $50 target means $250 billion. Only a handful of crypto assets have ever been worth that much, so a target like that is a claim that this coin will join them.
Two refinements make the check sharper. First, use the supply the coin will have by the target date, not just today's. If another 5 billion coins unlock over the next two years, the same $10 price would mean $100 billion. Fully diluted value gives you that ceiling. Second, compare with coins that do a similar job. If the biggest project in its category is worth $8 billion, a target that puts this one at $50 billion assumes it beats its rivals by a wide margin. The What if calculator on KryptoKap runs this math for any coin.
Why market cap can move more than the money behind it
When one buyer lifts the price 5%, all 100 million coins are revalued. $200,000 of buying adds $5 million of market cap, 25 times the money that actually moved.
Market cap reprices every coin at the latest trade, even the ones that didn't move. That's how small amounts of money can create large headline changes, especially in thin markets.
Take a coin with 100 million in circulation at $1.00, a $100 million market cap. Its order book is thin, so one buyer spending $200,000 eats through the sell orders and lifts the price to $1.05. Every one of the 100 million coins is now valued at $1.05, so market cap rises to $105 million. That's $5 million of new market cap from $200,000 of buying, 25 times the cash. The same thing works in reverse, and a modest sell order in a thin market can erase millions of market cap in minutes.
This is why headlines like "$100 billion added to crypto today" don't mean $100 billion of new money arrived. It also explains why small coins swing harder than large ones. To judge how real a market cap is, compare it with 24-hour volume and order book depth. A coin worth $100 million that trades $20,000 a day can't be sold anywhere near its headline value, while one trading $30 million a day has a much more meaningful number.
Key terms
Market cap
Price × circulating supply.
Circulating supply
Coins out in the market and able to trade.
Rank
A coin's position when sorted by market cap.
Large cap
Informally, coins worth tens of billions of dollars.
Where the number falls short
How much money went in. Prices are set by the most recent trades, so a coin's market cap can rise by far more than the money that actually bought it.
What you could sell for. Selling a large share would push the price down long before anyone collected the headline figure.
Whether the supply count is right. It rests on a data provider's estimate of how many coins are in circulation.
What's still to come. Locked and unissued coins are left out. Fully diluted value counts them.
What people get wrong
A low price doesn't mean a coin is cheap or has more room to grow. A $0.01 coin with 500 billion coins is already worth $5 billion.
Market cap isn't the amount of money invested. Prices are set by recent trades, so a market cap can rise or fall far more than the money that actually moved.
Why it matters
It's the fairest quick way to compare coins of very different prices, and the first number to check before believing any price prediction.
Common questions
Why do sites show slightly different market caps?
They use different prices and different estimates of circulating supply.
Which coins count as large caps?
There's no official line. Coins worth tens of billions are usually called large caps.
How is total crypto market cap calculated?
Sites add up the market caps of every coin they track. Because each provider tracks a different list and uses its own supply estimates, totals differ between sites by a few percent. Stablecoins are included, so part of the total is dollars parked in crypto rather than price growth.
