Bitcoin’s Throne Shakes as Altcoins Rally—Is the 2025 Altseason Finally Here?

BTC dominance slides below 45% for the first time since 2021—triggering a feeding frenzy for ETH, SOL, and meme coins. Traders pile into ’the next big thing’ while Wall Street analysts mutter about ’greater fool theory’ over martinis.

Ethereum flips its post-merge script: Layer-2 adoption cuts gas fees by 80%, while Solana’s validator overhaul bypasses last year’s congestion disasters. Even Bitcoin maximalists glance sideways at the ROI charts.

The kicker? Regulators still can’t decide if crypto is a security, commodity, or their lunch money. Place your bets—the casino stays open 24/7.

• Crypto cash rotation from Bitcoin to the altcoin market by institutional investors has triggered bullish sentiment for most altcoins.

• The TOTAL3 has rebounded from a crucial support level amid the altseason reckoning.

As Bitcoin (BTC) price attempts to rally beyond $105k, following the recent rebound catalyzed by the macroeconomic crisis and rising demand from institutional investors, the altcoin industry has signaled bullish sentiment. For the first time since U.S. President Donald Trump took office earlier this year, ethereum (ETH) price teased above $2.7k.

The fear of further crypto correction has significantly diminished as shown by the notable rise in Ethereum’s fear and greed index above 70 percent. Furthermore, the total crypto market cap surged to nearly $3.5 trillion in tandem with the ongoing major stock index recovery.

Closer Look at Altseason 2025 

For the past two years, Bitcoin price rally dominated the cryptocurrency market, mostly catalyzed by the rising demand from institutional investors led by U.S. spot BTC ETF issuers and Strategy Inc. However, a notable shift in Bitcoin dominance –  down 5 percent in the past seven days to 62 percent at the time of this writing – has hinted at a potential start of the altseason 2025.

According to a popular crypto analyst Gert van Lagen, the recent drop in Bitcoin dominance has coincided with a notable surge in TOTAL3, which excludes Ethereum’s market cap. From a technical analysis standpoint, Lagen highlighted that the TOTAL3 will likely experience a parabolic rally beyond $5 trillion in the coming months following a successful bounce from a cup and handle pattern.

The altcoin 2025 hype is evident from the notable memecoin FOMO, led by PEPE, Moo Deng, Floki, Dogecoin, and Neiro, among many others. With the notable improvement in crypto regulations in the United States among other nations, a major altseason is brewing before the end of 2025.
