Why are you coming here? Every day I send your mother that stuff, falling every day, losing every day.

Now, everyone is talking about the arrival of the altcoin season, but no one tells you how to accurately judge its onset.
In fact, there is an important indicator for the rise of altcoins, which is the 'Bitcoin Market Share'.

When the Bitcoin market share rises, it means that funds are flowing into Bitcoin; at this time, Bitcoin is thriving, and altcoins are in a bear market;
When the Bitcoin market share declines, it indicates that funds are flowing out of Bitcoin or into altcoins, which is the signal for the altcoin bull market.

Looking back in history, in March 2017, the Bitcoin market share dropped from 80% to 30%, and subsequently, the altcoin bull market erupted; in January 2021, the share dropped from 70% to 40%, which also triggered the altcoin bull market. In December 2024, the current Bitcoin market share is 56%, and it has fallen below the upward channel.

The last time the Bitcoin market share plummeted was in January 2021, after which the rise of altcoins began to gain momentum. After breaking through in June 2023, Bitcoin continued to rise until November 2024, while altcoins consistently hit new lows, causing significant distress for retail investors. Now, the Bitcoin market share has fallen below the upward channel, which may indicate that we are about to welcome a new round of altcoin season.
