Google Searches for Altcoins and Ethereum Reach Multi-Year Highs as ETF Filings Accelerate

TLDR

• Google searches for “altcoin” and “Ethereum” have reached multi-year highs
• Over 31 altcoin ETF applications were filed in the first half of 2025
• Corporate treasuries are expanding beyond Bitcoin to include Ethereum, Solana, and Chainlink
• Ethereum price has climbed 30% in the past week, approaching its all-time high
• Bitcoin dominance has fallen from 65% to 59%, indicating growing investor interest in altcoins

The cryptocurrency market is witnessing a resurgence in altcoin interest, with Google search data showing a sharp rise in queries for “altcoin” and “Ethereum.” According to Google Trends, searches for “altcoin” have reached their highest level since 2021, while “Ethereum” searches have hit a two-year peak.

This surge in retail curiosity comes at a time when institutional players are showing greater interest in cryptocurrencies beyond Bitcoin. The first half of 2025 alone saw at least 31 altcoin ETF applications submitted to US regulators, marking a new phase in crypto investment products.

Among the most talked-about filings, Canary Capital submitted a proposal in March for a SUI spot ETF to track the Sui token directly. Cboe BZX followed by requesting approval to list Canary’s fund, which could become the first US ETF to hold SUI tokens.

The enthusiasm extends beyond SUI. Bloomberg Intelligence analysts Eric Balchunas and James Seyffart have given high approval odds for several altcoin ETFs. They estimate a 95% chance of approval for Solana, XRP, and Litecoin ETFs, with Dogecoin, Cardano, Polkadot, Hedera, and Avalanche applications receiving odds as high as 90%.

Corporate Treasuries Embrace Altcoins

Corporate treasury strategies are evolving to include a wider range of cryptocurrencies. Ethereum has become a preferred reserve asset for several firms, with companies like Metaplanet, BitMine, and SharpLink Gaming holding billions of dollars worth of Ether.

Many of these companies are also staking their holdings to earn additional yield, showing a more sophisticated approach to crypto asset management. The trend extends to other altcoins as well.

Solana has gained traction in corporate treasuries, with DeFi Development Corp holding nearly one million SOL tokens worth approximately $200 million. The company stakes these tokens to generate yield. Similarly, Upexi increased its SOL holdings to two million in July, with most being staked.

Chainlink has also entered the treasury conversation with the launch of the Chainlink Reserve on August 7. This mechanism converts usage fees and enterprise payments into LINK tokens to enhance the network’s long-term sustainability.

Market Performance Reflects Growing Interest

The increased attention is reflected in market performance. Ethereum’s price has climbed 30% over the past seven days and 78% year-to-date, trading at about $4,722. This places it just shy of its all-time high of $4,878.26 set on November 10, 2021.

Other major altcoins have also posted strong gains over the past week, including XRP (+10%), SOL (+19.3%), SUI (+15%), and LINK (+43%). The total crypto market cap has risen 2.31% in the past 24 hours, reaching $4.11 trillion, with daily trading volume climbing 30.31% to $237.92 billion.

Bitcoin’s dominance has declined from 65% to 59% over two months, indicating a gradual shift in investor preferences toward altcoins. Ethereum, as the largest altcoin, has surged 81% over the past 90 days compared to Bitcoin’s 17%.

The Altcoin Season Index has risen to 39 from 29 a month ago, moving closer to the 75 threshold often associated with a full altcoin season. Market analysts describe this movement as a potential “bull flag” that could lead to a breakout.

On-chain data shows that decentralized exchange (DEX) trading volumes hit a quarterly record of $898 billion in Q2 2025, despite a softening in centralized spot trading volumes. This suggests growing activity in the altcoin space beyond mainstream exchanges.

The current market conditions appear to mirror those seen in 2017 and 2021, when altcoin seasons followed Bitcoin halvings. The total altcoin market cap has reached a three-month high of $1.67 trillion, while Bitcoin’s market cap remains at $2.39 trillion.
