The Five Crown Assets
Each day, we measure these five cryptocurrencies:
Data source: CoinGecko API (free tier). All prices measured in USD.
Measurement: Daily at 00:00 UTC. Calculation begins at 00:05 UTC.
Three Core Metrics
1. 24-Hour Return
How much the asset gained or lost in the last 24 hours. Negative = losing.
Example: FUSE rising 6.6% in 24h while PONS dropped 3.2%
2. 7-Day Drawdown
drawdown₇d = (price_now / peak) - 1
How far the asset has fallen from its recent peak. Measures recovery distance.
Example: Peak 7 days ago was $85,400, now $81,000 = -5.1% drawdown
3. 24-Hour Realized Volatility
σ = stddev(hourly_returns)
volatility = σ × √24
How much the asset bounces around. Higher = more unstable.
Example: FOUR showing 0.32 annualized volatility (32%) over the past 24 hours
Scoring & Percentiles
Each metric is ranked against the other four assets on a 0–100 percentile scale, where higher percentile = more cope.
Weighted Cope Score
Negative 24-hour return is weighted highest (60%) because on a green day, the worst performer is the one that didn't go up.
Winner: Asset with the highest copeScore wins the daily Crown.
Tiebreaker Rules
If two or more assets have identical scores:
- 1.Worse raw 24-hour return. The one that lost more (or gained less) wins.
- 2.Deeper 7-day drawdown. The one that fell further from its peak.
- 3.Alphabetical ticker. FOUR beats PONS in a 3-way tie.
