Will altcoin repeat the uptrend of 2021 when the search volume on Google reaches its highest level in 5 years?

The cryptocurrency market has recorded a rise to the sky of 2.31% in the past 24 hours, bringing the total market capitalization to 4.11 trillion USD. The daily trading volume has also risen to the sky by 30.31%, reaching 237.92 billion USD, according to information from CoinMarketCap.

The announcement of new US CPI data has triggered a market-wide recovery, with Bitcoin (BTC) reaching a new all-time high of nearly 124,000 USD. This has brought significant benefits to altcoins.

Signals from retailers: Search volume hits a five-year high

The interest of retail investors seems to be shifting towards altcoins.

According to data from Google Trends, global searches for the term "altcoin" have reached their highest level in five years, exceeding the threshold of 50/100.

Capital flows into altcoins

The total market capitalization of altcoins has reached a three-month high of 1.67 trillion USD, although it is still lower than Bitcoin's 2.39 trillion USD. However, the capital rotation is clearly underway.

According to data from Glassnode, Bitcoin's dominance level has dropped from 65% to 59% in just two months.

Merlijn The Trader described the latest movement of this index as a "bull flag" ready for an explosion, emphasizing that a complete shift from BTC to altcoin could lead to "explosive" volatility.

Outstanding Altcoin! ETH leads

In the past 90 days, altcoins have outperformed Bitcoin, with memecoins like BUILDon (B), MemeCore (M), Pudgy Penguins (PENGU), SPX6900 (SPX), and Conflux (CFX) recording significant increases.

Ethereum (ETH), the largest altcoin, has risen to the sky by 81% during this period, while Bitcoin only rose by 17%. According to Polymarket, the probability of ETH reaching a new all-time high (ATH) before August 31 is 80%.

As the altcoin season is gradually taking shape, it remains unclear whether the four-year cycles will repeat in 2025.

Does history repeat itself like in 2017 and 2021?

History shows that altcoin seasons often occur in the year following a Bitcoin halving. Altcoins seem to be preparing for a price surge similar to what happened in 2017 and 2021.

The altcoin season index is gradually changing and providing hints. However, the altcoin season is still in its early stages, with a real explosion predicted to occur when more than 75 altcoins dominate over Bitcoin.
