The Altcoin Cycle Signal measures whether the market favors bitcoin versus all altcoins. During Bitcoin Season, bitcoin is likely to outperform the basket of all altcoins and during Altcoin Season this dynamic inverts. The signal is meant to be largely agnostic to which altcoins in particular an investor holds. The Altcoin Cycle Signal is based on price data of the top 250 altcoins by market capitalization (excluding stablecoins). This metric is updated daily at 10:15 UTC, providing us with the previous day's data point at this time.

For more information on its interpretation and methodology see this dashboard.
