CryptoArrowLoadingCryptoArrowLoadingCryptoArrowLoadingBitcoin since 2013, log scale. Every fall measured from its own peak, so the deeper falls draw deeper.
The average of the five. And that is Bitcoin, the steadiest asset in the market. Most alts fell further.
Your coins, your weights, and how each one has actually moved when Bitcoin fell. Takes 30 seconds, and your holdings are never stored.
No account, nothing to sign up for, nothing to worry about.
Coins in the same sector tend to move as one. Count how many separate bets you are actually holding.

Cycle →The check grades the structure of a crypto portfolio from 0 to 100 and translates the score to a letter: 85 or higher is an A, 70 a B, 55 a C, 40 a D, anything lower an F. Structure means the things you control before the market decides anything: how concentrated the book is, whether the coins are secretly the same bet, and how hard the portfolio has historically moved. The five checks, with the exact weight each carries:
Coins that move together are one bet wearing several tickers. Holdings are clustered by how their real daily returns have correlated, and the check scores how many independent bets the portfolio truly holds. This is the heaviest-weighted check, and a portfolio that turns out to be one bet cannot grade as healthy no matter how the other checks score.
How much of the portfolio sits in the single largest position, measured the way index providers measure it (a Herfindahl reading across every weight). A book that is mostly one coin rises and falls as that coin.
Which market sectors the holdings actually belong to, from the same sector data the Sectors page ranks. Ten coins from one narrative are one story, told ten times.
How much of the book sits in small-cap coins (under $100 million market cap), which have historically moved harder in both directions than majors.
How hard the portfolio has actually been swinging, weighted across each holding's recent 30-day movement and read against Bitcoin's own.
One rule sits above the weights: when the correlation model finds fewer than two truly independent bets, the composite is capped no matter what the other checks say. A portfolio that is one bet in five tickers cannot buy its way to an A with tidy percentages. The full math is documented on the health score methodology page.
The stress figure the tool shows is not invented. It is the average of Bitcoin’s five major peak-to-trough drawdowns, about 70%, applied to the specific portfolio you typed in and scaled by how hard each of your coins has historically moved relative to Bitcoin. The episodes, deepest first:
Bottomed near $170. Took about three years to regain the old high.
Bottomed near $3,100. Took about three years to regain the old high.
Bottomed near $15,500 after FTX failed. Took about 2.4 years to regain the old high.
A mid-cycle drop inside a bull market. Set a new high six months after the peak.
Halved in two days. Regained the old level about five months later.
Recovery took anywhere from five months to over three years, depending on the episode. How long past falls ran, and how far the market sits from its peak today, is the whole subject of the free Cycle page. How many independent bets the market itself is currently running is the Real Bet Count.
Yes. The full check runs with no signup, no email, and no wallet connection. You type in what you hold as percentages, and the grade, the crash math, and every underlying check render on the page.
No. The tool never touches a wallet, an exchange account, or a private key. You describe your holdings yourself, and nothing you type is stored unless you create an account and save them.
Live market prices and real daily price history. The correlation and volatility reads come from measured return series, not from static assumptions about what coins are supposed to do.
Bitcoin's five major drawdowns since 2013 average about 70% peak to trough. The tool applies a fall of that scale to your specific portfolio, scaled by how hard your coins have historically moved relative to Bitcoin, and states the modeled loss in dollars. It is a description of what an average historical crash would have done to this structure, not a prediction of the next one.
No. CryptoArrow is a publisher of crypto analytics. Every read on this page is descriptive: it measures the structure of the portfolio you typed in and reports what it found. Nothing here tells you what to buy, sell, or hold.
It says nothing about future returns, entry or exit timing, or whether any coin is a good project. A portfolio can be structurally sound and still lose money; the grade measures structure, which is the part you control.
More specific questions, answered the same way: how to check your crypto portfolio’s risk, whether your portfolio is too concentrated, and what a crash would do to it.
