Now everyone knows that the altcoin season has arrived, but actually no one tells you how to judge if it has really come!

The key indicator for the altcoin market rally is the BTC market share.

Increasing market share: This means funds are flowing into BTC, everyone is chasing Bitcoin, and altcoins continue to be in a bear market.

Decreasing market share: Funds are flowing out of BTC and into altcoins, indicating that altcoins are entering a bull market.

Looking back at history:

In March 2017, BTC's market share dropped from 80% to 30%, leading to an explosion of the altcoin bull market.

In January 2021, the market share fell from 70% to 40%, and the altcoin bull market was launched again.

Now it is December 2024, and the market share has dropped to 56%, breaking below the upward channel.

The last significant drop in market share was in January 2021, after which altcoins began to rise strongly until June 2023, when the market share broke through and continued to rise.

Recently, the market share has been falling, and almost all altcoins are setting new lows, making it difficult for retail investors to hold their coins. Now, the market share has once again fallen below the upward channel, and a new altcoin season has officially begun!
