During the 2025–2026 crypto crash, our top-quintile tokens lost 26% while bottom-quintile lost 70%.
We didn't cherry-pick this result. We tested across 3 time windows, 355–412 tokens each, with proper out-of-sample methodology. Here's what we found.
What Is the Vitality Score?
ZARQ rates 15,000+ crypto tokens on a 0–100 "Vitality Score" measuring ecosystem health across 5 weighted dimensions:
- Ecosystem Gravity (20%) — protocol count, TVL, stablecoin presence on the token's chain(s)
- Capital Commitment (20%) — TVL retention, yield pool density
- Coordination Efficiency (15%) — DeFi category diversity, audit coverage
- Stress Resilience (25%) — NDD stability, crash probability, drawdown behavior
- Organic Momentum (20%) — TVL trend, price trend, rating trend
Grades range from S (≥85, exceptional) through F (<25, minimal).
The Backtest: 3 Windows, No Look-Ahead Bias
We reconstructed a historical Vitality proxy at 3 past dates using only data available at that time, then measured forward returns:
| Window | Score Date | Forward Period | Tokens |
|---|---|---|---|
| A | Jan 2024 | Jan 2024 → Jan 2025 (12 months) | 355 |
| B | Jan 2025 | Jan 2025 → Jan 2026 (12 months) | 363 |
| C | Jul 2025 | Jul 2025 → Feb 2026 (crash, 8 months) | 412 |
For each window, we split tokens into quintiles by Vitality Score and measured median returns.
The Results
Window C (the crash window) — statistically significant
| Quintile | N | Vitality Score | Median Return |
|---|---|---|---|
| Q1 (TOP) | 82 | 52.5–67.7 | -26.1% |
| Q2 | 82 | 43.6–52.3 | -48.8% |
| Q3 | 82 | 38.3–43.5 | -55.4% |
| Q4 | 82 | 33.3–38.2 | -56.1% |
| Q5 (BOTTOM) | 84 | 26.7–33.3 | -70.4% |
Q1–Q5 spread: +44.3%. Perfectly monotonic (4/4 steps). t-statistic: 3.35, p-value: 0.0008.
Windows A and B
Window A (bull market): Q1–Q5 spread +9.3%, NOT statistically significant (p=0.556). The model doesn't predict upside well.
Window B (bear market): Q1–Q5 spread +27.1%, perfectly monotonic (4/4), but NOT significant (p=0.392) due to high variance.
Which Dimension Matters Most?
We tested each dimension independently. The answer is clear:
| Dimension | Window B Spread | Window C Spread |
|---|---|---|
| Stress Resilience | +66.1% | +52.5% |
| Organic Momentum | +1.1% | +6.2% |
| Capital Commitment | -1.9% | +3.2% |
| Ecosystem Gravity | -11.4% | -8.3% |
| Coordination Efficiency | -18.5% | -8.6% |
Stress Resilience dominates. Ecosystem Gravity and Coordination Efficiency actually show negative spreads — they measure ecosystem quality but don't predict returns.
Being Honest About Limitations
- Only Window C is statistically significant. Windows A and B show the right direction but aren't conclusive alone.
- The model predicts downside protection better than upside performance.
- Sample sizes are 355–412 tokens per window — large for crypto research but small in absolute terms.
- Survivorship bias: tokens that died during windows are excluded from the analysis.
- Crypto returns are fat-tailed and non-normal — p-values should be interpreted cautiously.
- Past performance does not guarantee future results.

The Bottom Line
Vitality Score is most valuable as a crash protection indicator. Tokens with high ecosystem quality — especially high Stress Resilience — lost significantly less during the 2025–2026 crash. The signal is consistent across all 3 windows but only statistically significant in the crash window.
This doesn't mean high-Vitality tokens will go up. It means they're less likely to collapse when the market turns.
