The Five Crown Assets

Each day, we measure these five cryptocurrencies:

BTC
Bitcoin
Price reference
ETH
Ethereum
Price reference + launch pair
LINK
Chainlink
Price reference
SOL
Solana
Price reference
CASHCAT
Cash Cat
Robinhood Chain proxy

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

return₂₄h = (price_now / price_24h_ago) - 1

How much the asset gained or lost in the last 24 hours. Negative = losing.

Example: BTC at $81,000 today, $76,000 yesterday = +6.6% return

2. 7-Day Drawdown

peak = highest price in last 7 days
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

hourly_returns = log(price[i] / price[i-1]) for each hour
σ = stddev(hourly_returns)
volatility = σ × √24

How much the asset bounces around. Higher = more unstable.

Example: BTC's last 24 hours = 0.32 annualized volatility (32%)

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

copeScore = (60% × return_percentile) + (30% × drawdown_percentile) + (10% × volatility_percentile)

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. 1.Worse raw 24-hour return. The one that lost more (or gained less) wins.
  2. 2.Deeper 7-day drawdown. The one that fell further from its peak.
  3. 3.Alphabetical ticker. BTC beats CASHCAT in a 3-way tie.
