01 How to read the chart
Three things carry all the information
Size is market cap. Market cap is the current price multiplied by the number of coins in circulation. A bubble twice the width of another is not twice the value — area grows faster than width, and the scale is compressed on purpose, or Bitcoin alone would leave no room for anything else. Read size as a rough rank, not as a ratio you can do arithmetic with.
Color is price change over the period. The hue gives you the direction — green up, red down — and the brightness gives you the size of the move, scaled to what counts as a large move over that timeframe. Grey means a coin barely moved at all, which is rarer than people expect — so a quiet day is a dark board, not an empty one. Read the brightness, not the fact that there is color at all.
The period changes the picture completely. The same board over 24 hours and over a year can look like two different markets, and both are correct. A coin can be green on the day and deep red on the year. Neither number is the "real" one; they answer different questions.
One thing this chart never tells you:
Green means the price went up. It does not mean the price will go up.
That sentence is the whole reason this page exists rather than a leaderboard. Every visual that ranks things by recent performance invites the reader to mistake the past for a forecast. Bubbles are unusually good at this, because a big bright green circle feels like an argument. It is not one. It is a description of what already happened.
The longer version, with the exact color thresholds and the parts of the market a bubble chart cannot show: how to read a crypto bubble chart.

| NEARNEAR Protocol | $2.28 | -5.16% | $350M |
| JSTJUST | $0.1051 | -5.09% | $56M |
Every coin in these two tables traded at least $10M in the past 24 hours — that is a volume floor, and it does not change with the period above. It is there for a reason. Without it, the top of any gainers list fills up with tokens that moved 400% because somebody bought a few thousand dollars' worth on a market where nothing else happened that day. The percentage is real and completely uninformative.
A large move on thin volume is a thin move. It tells you that one participant did something, not that a market changed its mind. When you see an unfamiliar name at the top of a gainers list anywhere, the volume column is the first thing worth looking at — and on most sites it is the column that gets cropped on mobile.
03 Limits
What the bubbles don't show
A market map is a compression of reality. Four things get compressed out completely, and no amount of staring at the board will recover them.
Liquidity. Size is a headline figure, not a measure of what you could buy or sell at the price shown. Two bubbles the same size can be worlds apart in how much money it takes to move them.
Money actually invested. Market cap is a multiplication: price times units in circulation, where the price is whatever the last trade happened at, however small that trade was. A two-billion-dollar cap is not two billion dollars that went in.
Supply still locked up. Most tokens circulate a fraction of what will eventually exist, with the rest released to a team, to investors or to a treasury on a schedule. A bubble is drawn from today's count and knows nothing about next quarter's.
Why the price moved. Every green bubble looks alike, whatever put it there — a launch, an exchange listing, an index rebalance, a group chat. The chart carries the result and not the cause, and that gap is usually filled in by somebody with a reason to fill it.
Each of those is worked through properly in the guide — along with the one that matters most, which is stated further up this page: the chart says nothing at all about what happens next.
04 The app
What the full board adds
This page is a fixed cut of the market: the top 100, four periods, prices in dollars, and no way to ask it a question. That is what a page should be. The board it was cut from is the app — free, no ads, no account, and it runs in a browser tab as well as on a phone.
All 1,000 coins
Ten times what fits here, down to the coins a top-100 list never shows. The same board, drawn from the same data.
7 periods, from 15 minutes
The four above plus 15 minutes, 1 hour and 4 hours — the ones that answer what is happening now rather than what happened today.
Every coin opens
Tap a bubble for its price history, supply, what the project actually is and where to read further. Not a redirect to an exchange.
Favorites
The coins you follow as a board of their own. Kept on your device — there is still nothing to sign up for.
Filters and search
Narrow the board to a category, an ecosystem or an exchange, or find any coin by name across the whole market.
24 currencies
Prices in euro, yen, rupee or real instead of dollars. Same picture, numbers you can read without converting.
05 Comparison
Why a map instead of a list
Almost every crypto site opens on a ranked table: number one Bitcoin, number two Ethereum, scroll for the rest. That is the right shape for a question you already have — which is why the gainers and losers further up this page are tables. It is the wrong shape for the question most people actually arrive with, which is some version of "what is going on today".
A table is a lookup. Exact price, exact rank, a figure you mean to write down, two coins set side by side. It costs a scroll and a little arithmetic, and it hands back an answer as precise as the question was.
A map is a first impression. Whether the day belongs to the whole market or to three coins. Whether the large caps and the long tail disagree. Whether a name you don't recognize is quietly enormous. None of that needs a number read off the screen — it is shape and color, and it lands before you focus on anything.
The board has two of these maps, and the buttons on it switch between them. Bubbles leave space between coins, so one bright circle carries across the whole board; the heatmap gives every coin a rectangle and leaves no gaps, so more names fit and coins of similar size are easier to tell apart. Which to reach for, and what both of them leave out, is worked through in the guide.
A table tells you the number. A map tells you which number to look up.
06 A different question
"Is crypto a bubble?"
Some people arrive here looking for the other meaning of the word — whether cryptocurrency as a whole is a speculative bubble. That is a different subject and this is not the page for it. Wikipedia's article on cryptocurrency bubbles is a reasonable starting point.
"Bubbles" here is a chart type: circles sized by market cap. Nothing on this page is a claim about whether any asset is over- or undervalued.
07 Independence
Who makes this
Crypto Heatmap is built by one developer, Shamil Shamilov. It runs on iOS, Android and the web.
It is worth being specific about what that means, because "independent" is a word every product uses:
No ads
None in the app, none on this page, and none planned.
No account
Nothing to sign up for. Favorites are stored on your device.
No paid tier
There is no feature behind a payment.
Tapping a coin opens the coin
It opens a screen with a chart and the numbers, not a redirect to an exchange with a referral code attached. There are no referral or affiliate links anywhere, including the links on this page.
None of that is a business model waiting to be switched on. It is the reason the app is small, and it is the thing worth checking before you trust anything else on this page.
Apps in this category are usually funded some other way — advertising, registration, or a cut of what you do after you tap a coin. Those are legitimate ways to run a product, and they are also the reason a chart can end up optimized for your next click rather than for showing you the market. You do not have to take anyone's word for which is which: an app's store listing states whether it contains advertising, and the app itself shows you where a tap goes.
The best-known board in this category is owned by a cryptocurrency exchange. The comparison page names it, puts the two side by side, dates every claim, and lists the cases where the other one is the better choice.
Get the app
The web app above is the same board, no install needed. iOS and Android also get it as a native app — scan a code or tap a cardone tap from here.
08 Questions
Common questions
Where do the numbers come from?
Our own API, which sources market data from CoinMarketCap. Nothing here is scraped from another site and nothing is estimated. The stamp under the board says which figures you are looking at: the ones baked into the page when it was last deployed, or the fresher set your browser fetched after loading.
How often does the board update?
Once per visit. The page arrives with figures already in it, which is why the first screen needs no request, and your browser then fetches a current snapshot — a few minutes old at most. It does not keep ticking after that: reload for a newer one.
Is it free?
Yes, and there is nothing to sign up for. No ads on this page or in the app, no paid tier, no trial that ends. Favorites in the app are kept on your device.
What does the size of a bubble actually mean?
Market cap: price multiplied by circulating supply. The scale is compressed so the largest coins do not crowd out everything else, so treat size as approximate rank rather than an exact ratio.
Why is a coin green over 24 hours and red over a year?
Because both are true. Price changes are measured against a starting point, and moving the starting point moves the answer. A coin that fell 70% over a year and rose 3% today is accurately described by both numbers.
What is the difference between the bubbles and the heatmap?
Only the shape. Both draw the same coins from the same two numbers, size for market cap and color for the price change. Bubbles leave space between coins, so a single large move carries across the whole board; the heatmap gives every coin a rectangle and leaves no gaps, so more names fit and coins of similar size are easier to tell apart. The buttons on the board switch between them.
Why are there no stablecoins?
Because color here means price change, and a coin pegged to a currency sits at zero every day. A dozen permanent grey circles, two of them among the biggest on the board, would take up a lot of room to say nothing. They get a board of their own instead — linked under the chart above — where color means distance from the peg, and the same coins turn out to have plenty to say. The app shows them alongside everything else and lets you switch them off.
Is this financial advice?
No. Nothing here is a recommendation, a forecast, or a signal. The chart describes price movements that already happened.
