Whether the alt season arrives depends on the decline in Bitcoin dominance, the inflow of funds into altcoins, and the warming of market sentiment. The current market shows signs of a rebound in some altcoins, but the full alt season has not yet arrived due to liquidity, retail investor participation and macro factors. The timing of the alt season index, on-chain data and other indicators + the proportion of Bitcoin market value in the total market value of the crypto market. A decline in dominance usually means that funds flow from Bitcoin to altcoins, which may indicate the arrival of the alt season. Summary: It is still a small test at present.
