Key Takeaways
After a sluggish start to 2025, altcoins are finally getting their moment in the sun.
With Bitcoin (BTC) setting new all-time highs above $100,000, capital appears to be rotating into altcoins, fueling a surge in interest and volume not seen since the last bull cycle.
Altcoins lagged behind BTC for much of the year, but June marked a clear turning point. Now, signs suggest we may be entering a full-fledged altseason.
One of the clearest signals of a brewing altseason is retail interest, and it’s heating up fast.

According to Google Trends, search volume for “altcoin” has soared to a score of 90 out of 100. That’s just shy of its peak during the 2021 bull market frenzy.
The timing lines up with Bitcoin’s recent push above $119,000, hinting that mainstream investors are shifting focus toward lower-cap opportunities.
Trading volumes back up the trend. On July 2, altcoin trading on Binance Futures hit $100.7 billion—its highest level since February—highlighting renewed retail momentum across the board.
Several key indicators are flashing signs that altcoins are gaining strength.
The Altcoin Season Index, which measures how altcoins perform relative to Bitcoin over a 90-day period, jumped from 12 to 53 in just one month.
A reading above 50 is generally considered the start of altseason—and we’re there now.
This surge suggests that after months of lagging, altcoins are starting to outpace Bitcoin.

Bitcoin dominance—the share of the total crypto market held by BTC—has dropped to around 64%, down from over 70% just weeks ago.
That’s a steep decline, and one that historically precedes altcoin rallies.
Importantly, this shift is happening while Bitcoin’s price remains strong, signaling fresh money entering the market rather than just profit rotation.
If BTC dominance dips below 60%, it could confirm the start of a broader altcoin breakout, as seen in previous cycles like 2017–2018 and 2020–2021.
Futures Open Interest (OI) across major altcoins—including Ethereum (ETH), Solana (SOL), and XRP —has also surged.
Each has approached or exceeded $1 billion in open contracts, showing increased speculative activity.
Rising OI alongside price action is typically a bullish indicator, as it suggests traders are betting big on further gains.
After months of underperformance, altcoins are clawing their way back into the spotlight.
With trading volumes up, search interest spiking, and key market metrics aligning, all signs point to the early stages of an altseason.
If momentum continues—and especially if Bitcoin dominance dips below 60%—traders could be in for a wild second half of 2025.
