What would a crash do to my crypto portfolio?

Updated 2026-08-01 · Descriptive analytics, not advice

History gives a measurable answer. Crypto has repeatedly drawn down 50 to 80 percent from its peaks, and each coin fell by a different, recorded amount. Applying a historical-scale crash to your current weights turns those records into one dollar figure. CryptoArrow's free checker computes that worst-case figure in about 30 seconds.

What a crash stress test is

A stress test replays the scale of past declines against a portfolio's current weights. Crypto's own record includes multiple drawdowns beyond 70 percent for Bitcoin and deeper for most altcoins, all dated and public. The test is mechanical: recorded decline profiles applied to entered weights. It is a reading of history, not a forecast that a crash is coming.

Why the dollar figure matters

Percentages abstract the loss away. The same drawdown reads very differently as a percentage and as the dollar amount it removes from the portfolio you actually hold, which is why the checker expresses the worst case in dollars for the value you enter.

The free Portfolio Risk X-Ray computes the historical worst-case figure for any set of tickers and weights, alongside the concentration and correlation structure that drives it.

Common questions

Is this a prediction that a crash is coming?

No. The test replays the scale of recorded past declines against current weights. It says what a crash of historical scale would have done, not whether or when one will happen. Nothing on CryptoArrow forecasts a price.

Which crashes does it use?

Drawdown profiles from crypto's own dated record, where Bitcoin has repeatedly fallen more than 70 percent from a peak and most altcoins fell further. The methodology pages document how the profiles are applied and their stated limitations.
