HIFI Altcoin Season Index (Total3 vs BTC)

This indicator helps you determine whether the crypto market is in an "altcoin season" or a "bitcoin season." It doesn't compare every single altcoin to Bitcoin individually; instead, it uses a more efficient approach.

Value below 25: BTC is outperforming TOTAL3, indicating a BITCOIN SEASON. 👑

Value between 25 and 75: The market is in a mixed or neutral phase. 🤷
