What is Crypto Bubbles? The crypto market drawn as bubbles

Definition

Crypto Bubbles in plain words: what it is and where it came from

The simplest version: Crypto Bubbles is a free app that draws the cryptocurrency market as a board of colored bubbles. Each bubble is one coin. Its size corresponds to market capitalization — the total valuation of the project — and its color and intensity show the percentage price change over a chosen time window, from an hour out to a full year. Instead of reading a thousand table rows, you look at one screen and know in a second whether the market is celebrating or bleeding.

The project's story is pleasantly atypical for crypto: no ICO, no token, no profit promises. Behind the app is an independent developer in Germany who built the web version first and added iOS and Android apps only after it caught on — details which, like every product fact in this article, we attribute to the official cryptobubbles.net site. The tool spread organically because it does one thing and does it very well: it shows you the state of the market faster than you can finish asking the question.

Let's set expectations immediately: this is a viewer. Crypto Bubbles doesn't sell crypto, doesn't hold it, and doesn't advise. That's exactly why using it requires no account, no phone number and no scan of your ID — the app never touches your money, so there's nothing for KYC procedures to protect. A healthy rule for your whole crypto life: the less a tool knows about you, the better, as long as it isn't holding anything of yours.

Why bubbles work: two seconds ahead of consciousness

This visualization's appeal has solid grounding in perceptual psychology. Size and color belong to what researchers call preattentive attributes — the brain processes them automatically, in a fraction of a second, before you consciously "read" the image. You find the largest object on screen and the brightest color effortlessly, by reflex. Numbers work the opposite way: each one has to be read, interpreted and compared with its neighbor, and working memory handles a handful of values at once, not a thousand.

So a bubble board offloads the entire job of comparison from your conscious mind onto your visual system. A red sea with one green island; a memecoin flaring like a signal rocket after a 60% run; a Bitcoin giant next to which the fashionable token of the month looks like a pea — all of that is information you see before you can think. The same principle is why a weather map beats a table of temperatures and a subway map beats a timetable.

The pun

"Crypto bubbles" — circles on a screen and bubbles in history

The app's name is a neat piece of irony, because the phrase "crypto bubbles" has a second, older meaning: speculative bubbles, which this market is famous for like no other. A bubble is a stretch of time when prices detach from any sensible valuation, driven purely by the belief that somebody will pay more tomorrow. Crypto's history has several; two are worth knowing, because they teach more than most investing courses.

Case study 1: the ICO mania, 2017. A PDF grandly labeled a "whitepaper" and an ERC-20 token thrown together over a weekend were enough to raise millions of dollars from strangers on the internet. Projects promised to revolutionize everything from logistics to lettuce, and total market capitalization multiplied more than tenfold in a year. The ending: in 2018 the market gave up the overwhelming majority of that value, and a huge share of the tokens from that wave never came anywhere near their highs again. The lesson: capital flowing indiscriminately into everything is not a bull market, it's a bubble.

Case study 2: leveraged euphoria, 2021. This time the fuel wasn't ICOs but leverage and cheap money: 20x futures, loans collateralized by tokens, "stable" protocols promising low-double-digit annual yields with no risk. When prices twitched downward, a cascade of forced liquidations wiped out, one after another in 2022, an algorithmic stablecoin, several funds and several exchanges that a quarter earlier had been treated as pillars of the industry. The lesson: leverage doesn't create value, it creates a queue for the exit — and the exit gets too narrow at precisely the moment everybody wants to use it.

And here's where the app comes back in: the bubble board is, perversely, a decent bubble barometer. When every time window glows lush green and memecoins are outrunning the entire rest of the market, history suggests caution rather than euphoria. How to read those sector rotations on a wide board is covered in our market map guide.

One historical caveat, because cynicism should cut both ways: "this looks like a bubble" is not a timing tool. Plenty of markets have looked overheated and then doubled before breaking. The board tells you what regime you're in; it does not tell you how long the regime lasts. Anyone who claims otherwise is selling something.

Exchange or personal safe: custodial vs non-custodial

Since Crypto Bubbles holds nothing, sooner or later you'll face the question of where to keep the coins you buy. There's one fundamental distinction. A custodial arrangement — an exchange account — works like a bank: the operator holds the keys, you have a login, a password and a way to recover access when you forget it. Convenient for trading, but your funds are exactly as safe as the operator is safe (and honest). A non-custodial arrangement — a wallet like MetaMask, or a hardware wallet — is a personal safe: only you hold the keys. Total control, and also total responsibility: a lost seed phrase means funds gone permanently, with no support hotline to call.

A sensible setup for most people: buy and trade on a regulated exchange with 2FA switched on, and move larger amounts you don't plan to touch for months into a wallet whose keys you hold. Not because exchanges "will definitely fail" — because 2022 demonstrated that they can.

Crypto Bubbles, CoinMarketCap or an exchange terminal?

These three tools get lumped together, but they answer three different questions: "what's happening?", "what is this?" and "how do I execute?"

Criterion	Crypto Bubbles	CoinMarketCap / CoinGecko	Exchange terminal
Core question	What's happening in the market?	What is this project? What are its numbers?	What price can I buy or sell at right now?
Format	A board of bubbles	Tables, rankings, coin profiles	Candles, order book, order form
Time to first conclusion	Seconds	Minutes	Minutes to hours (needs practice)
Depth of per-coin data	A basic card	Full: supply, pairs, exchanges, links	Full market depth: liquidity, spread, book
Executes trades	No	No	Yes
Account / KYC required	No (for viewing)	No (for viewing)	Yes
Best for	Fast orientation, anomaly radar	Project research	Executing decisions

A mature workflow uses all three in sequence: bubbles catch the topic, an aggregator lets you check it, an exchange — if the research holds up — executes. Skipping the middle step is the most popular shortcut to losses.

Your first week with the board, without spending anything

If you're starting from zero, here's a week that costs nothing and teaches more than a shelf of books. Days one to two: only look at the day window, and only answer one question — is the board mostly green or mostly red? Say it out loud. You're building a baseline. Days three to four: add the week window and compare. You'll discover coins that look great today and terrible over seven days, which is the first genuinely useful insight the board gives anyone. Day five: pick the three biggest movers and open their coin cards. Don't buy anything; just read what happened. Days six to seven: build a watchlist of ten coins you can explain to a friend in one sentence each. If you can't explain it, it doesn't go on the list.

At the end of that week you'll have something most people who've been in crypto for years lack: a sense of what a normal day looks like. Everything else — indicators, strategies, narratives — is easier to evaluate once you have that baseline. And it's worth repeating that none of it required an account, a deposit or a single transaction.

Three myths worth deleting early

• "A big green bubble means a good project." Size is capitalization and color is recent history. Together they say a large project went up. Neither says it's well built, fairly distributed or liquid enough to exit.
• "If it's on the board, it's been vetted." Inclusion follows market cap and data availability, not quality. The board is a mirror of the market, and the market lists plenty of things you shouldn't own.
• "Bubbles are for beginners, pros use candles." Professionals use overviews constantly — that's what a trading desk's wall of screens is. The board is a different altitude of the same map, not a simpler version of it.
