Cryptocurrency enthusiasts are abuzz as a key market signal has reappeared, sparking hopes of an incoming altseason. A "golden cross" has been confirmed for altcoins, suggesting the beginning of a major upward trend.

This pattern occurs when a short-term moving average crosses above a long-term moving average. It is usually employed on an asset's price chart to determine the beginning of an uptrend.

The last time this pattern emerged during the 2021 bull run, altcoins surged by an astonishing 28,000%, presenting a golden opportunity for investors to mint heavy returns.

Now, in 2025, the same setup has materialized on the cryptocurrency market charts, and it has already begun with altcoins surging more than 10%.

As seen in the chart above, the 20-week moving average (MA) has crossed above the 200-week MA, also known as the "golden cross."

This pattern emerged in the final quarter of 2021, and it quickly led to a massive surge in altcoins. At the time, Bitcoin's dominance fell below 40%, paving the way for altcoins to rally.

After the golden cross appeared, altcoins continued to surge in 2022, even as Bitcoin's dominance fell below 30%.

However, in 2023, Bitcoin dominance began to rise again, reaching as high as 70%, which hampered the recovery in altcoins.

But now, in 2025, Bitcoin dominance has dropped below 40% again, setting the stage for another altcoin rally.

The crypto derivatives market is heating up once again.
