This index measures market-implied expectations of digital asset price underperformance across the major cryptocurrency complex. It aggregates prices from the same diversified set of prediction market contracts as the corresponding appreciation index, with each constituent voting the inverse side to capture downside expectations for Bitcoin, Ethereum, Solana, and XRP. Movements in the index reflect changes in market-implied probabilities of downside realizations across the underlying assets, not directional price forecasts.
