Altcoins Stage a Fierce Rally: The Crypto Underdogs Are Biting Back in 2025

Move over, Bitcoin—altcoins are stealing the spotlight with their most aggressive rally since the last bull run. Traders are flipping the script as Ethereum, Solana, and other alt tokens surge past resistance levels. Here’s why the market’s dark horses are galloping ahead.

The Altcoin Awakening

After months playing second fiddle to BTC, altcoins are posting double-digit gains while Wall Street analysts scramble to update their 'crypto is dead' hot takes. Ethereum’s Shanghai upgrade finally delivered scalability promises, Solana’s outage-free streak hits 180 days, and even meme coins are shrugging off their 'degenerate' reputations.

Liquidity Shifts & The Institutional Flip

CEX data shows alt trading volumes spiking 40% week-over-week—a clear sign that sidelined capital is rotating out of stablecoins and into risk assets. Meanwhile, BlackRock’s new altcoin ETP filings suggest the suits are catching on (just three years late, as usual).

This isn’t 2021’s mindless altseason. Projects with actual utility—real yield protocols, ZK-rollups, and DeFi blue chips—are leading the charge while vaporware lags. The market’s voting with its wallet: build something useful or get delisted.

Altcoins aren’t just back—they’re rewriting the playbook. And if history repeats? This rebound’s got legs. (Though let’s be real—some hedge fund manager will still call it a 'dead cat bounce' right before it doubles.)

In Brief

• ETH price jumps 21% in three weeks, driven by massive liquidations and expectations around network upgrades.
• XRP reaches a new all-time high at $3.65, supported by clearer regulation in Asia and growing adoption by financial players.
• The Altcoin Season Index climbs to 59, while Bitcoin dominance falls to its lowest level since March.
• Capital rotation is underway, marking a possible lasting change in the crypto market structure, although caution remains warranted.

A Summer Marked by Giants : Ethereum and XRP Leading the Way

At the heart of this altcoin activity resurgence, two heavyweights have captured market attention. First, ethereum (ETH), which surged from $3,100 to over $3,750 between July 1st and July 20, 2025. According to CoinMarketCap data, this rally was accompanied by massive liquidations in derivatives markets and a notable influx of capital, confirming a robust recovery.

The current momentum is also explained by expectations around scalability upgrades. Thus, the Ethereum network is regaining ground in the overall crypto capitalization distribution.

Meanwhile, XRP has crossed a symbolic milestone. On July 17, it reached a new ATH of $3.49, before climbing to $3.65. This spectacular performance is directly linked to regulatory clarity in Asia and adoption by financial services platforms.

The phenomenon doesn’t stop there. Other cryptos, such as Dogecoin (DOGE), have also ridden this bullish wave, with a nearly 40 % increase over two weeks. This surge was amplified by the return of mentions of Elon Musk on social networks and renewed retail interest.

To gauge the scope of this movement, it’s also necessary to look at several key indicators :

• The Altcoin Season Index : 59 as of July 21, up sharply from the 28 recorded in early June. The confirmation threshold for an altseason is set at 75 ;
• The CMC Altcoin Index : 56, based on 100 altcoins compared to Bitcoin over 90 days ;
• Bitcoin Dominance (BTC.D) : falling to 60.49 %, its lowest since March. This decline indicates capital is redirecting toward higher potential yield assets.

These technical elements confirm a fundamental trend. While the altcoin season is not officially triggered yet, the mechanism is in place: Bitcoin’s decline, sector rallies, and indexes showing clear growth.

Capital Migrations : Infrastructure Cryptos Attract Attention

Beyond the rally of major altcoins, a second, more discreet but potentially more structural movement is emerging. Several infrastructure cryptos are seeing significant rebounds, driven by medium- and long-term usage narratives.

Chainlink (LINK) is currently trading around $19 and is again attracting institutional interest, notably thanks to its cross-chain interoperability capabilities. This functionality is considered essential in the tokenization of real-world assets (RWA) and future enterprise integrations.

The same applies to Cardano (ADA), whose price has risen over 50 % in a month, supported by new launches within its ecosystem and the expansion of stablecoin options.

Finally, Avalanche (AVAX) also shows a similar monthly performance, with analysts monitoring its innovations regarding “subnet upgrades”.

This shift of capital toward infrastructure projects is no coincidence. As market maturity progresses, investors appear to favor assets with a robust technological foundation and concrete adoption.

These cryptos are increasingly seen as specialized tools for targeted growth segments. In other words, the rise of these utility altcoins fits into a sectoral logic that far exceeds the simple speculative phenomenon observed with ETH or XRP.

The medium-term implications are significant. On one hand, this diversification could mean that future altseasons will no longer be generalized rallies but more selective sectoral rotation phases. On the other hand, if confirmed, this trend could redraw the capitalization map within the crypto market that has crossed the $4,000 billion mark.
