Now everyone knows that the altcoin season seems to have arrived, but no one tells you how to judge it. In fact, there is an important indicator for the altcoin bull market — the 'Bitcoin Market Share'.

When the market share rises, funds flow into Bitcoin, the big pie is sucking blood, and altcoins are in a bear market; when the market share declines, funds flow out of Bitcoin or into altcoins, signaling the start of the altcoin bull market.

In March 2017, the market share dropped from 80% to 30%, triggering the altcoin bull market; in January 2021, the market share fell from 70% to 40%, and the altcoin bull market erupted again. As of December 2024, the current market share is 56%, and it has fallen below the upward channel.

The last time the market share plummeted was in January 2021, after which altcoins surged. After breaking through in June 2023, it rose all the way to November 2024, during which altcoins hit new lows, leaving retail investors in agony.

Now that it has fallen below the upward channel, get ready for a new round of altcoin season!
