Google Searches for “Altcoin” Hit Highest Since 2021 as Crypto Interest Broadens
According to Google Trends, search interest for “altcoin” and “Ethereum” has hit multi-year highs, with altcoin searches at a five-year peak and Ethereum searches at a two-year peak.
This surge in retail interest coincides with a dip in Bitcoin’s dominance, which has historically signaled the start of a broader altcoin rally or “altseason”.
The renewed interest is supported by a significant increase in institutional investment, with digital asset funds seeing record inflows into Ethereum ETFs.

It seems retail attention is swinging back toward altcoins, with Google Trends showing search interest at its strongest level in five years. The last time activity was this high was around the early growth phases of Ethereum (ETH), a period that preceded one of the largest altcoin booms on record.

Gearing Up For Altseason

The surge in curiosity comes as Bitcoin’s market share retreats to around 60% from mid-summer highs. Historically, dips into the 59–61% dominance band have set the stage for stronger relative gains in assets like Ethereum, Solana and XRP. Ethereum has already surged past US$4.5K (AU$6.7K), marking multi-year highs.

Institutional flows point the same way. CoinShares reported record inflows of US$4.3B (AU$6.5B) into digital asset funds in late July, with Ethereum capturing US$2.12B (AU$3.5B) of that total, nearly double any prior weekly record for the asset.

Moreover, the total value locked (TVL) across the crypto industry just reached a new all-time high of US$300.5B (AU$461B).

So, we have this cocktail of Bitcoin dominance falling, more inflows into ETH ETFs, TVL reaching new ATHs, and retail search intensity, all mirroring the backdrop of 2017 and 2021. 

But this will go on as long as Bitcoin wants it; more BTC consolidation or sluggish performance can potentially keep the altcoin momentum going stronger, but any surge in dominance back toward the mid-60s and above levels would likely cut the rally short.

As per CoinGecko data, Bitcoin is currently trading at US$117.5K (AU$179K); no change in the last 24 hours despite the volatility that gripped the market last week.
