- Altcoin open interest reached a record $47B in August 2025, led by ETH, SOL, XRP, and DOGE.
- Google Trends searches for “altcoins” saw a sharp spike but remain below 2021 highs.
- The Total2 index is approaching a breakout above its 2021 all-time high.
Altcoin open interest has surged to a record $47 billion, marking the highest level ever recorded and signaling elevated market leverage.
Glassnode data shows that this figure marks the highest level recorded and has been steadily climbing since October 2024. Ethereum, Solana, XRP, and DOGE accounted for much of the increase.

Glassnode noted that the rise reflects greater concentration of leverage in the altcoin market. This can cause stronger price movements in both directions, creating conditions where rapid gains or losses are more likely. Analysts have warned that such leverage can make markets more sensitive to sudden shifts.
Search Interest in Altcoins Rising
Google Trends data showed a sharp rise in searches for “altcoins” during August 2025. Crypto analyst Miles Deutscher said the increase suggests the market may be entering “price discovery” territory.
Market commentator SightBringer clarified that the data reflects a surge in search speed rather than peak volume. Search levels remain below those seen in 2021 and late 2024. He described the current stage as a “pre-mania coil,” often seen before large market moves in past cycles.
Technical Setup Points to Potential Breakout
The TOTAL2 index, which tracks the crypto market excluding Bitcoin, is nearing a breakout above its 2021 high. Analyst el_crypto_prof shared a chart showing a multi-year price pattern that resembles the 2016–2017 cycle.
During that earlier cycle, the market experienced a period of consolidation, referred to as “Wave 1,” followed by a strong “Wave 2” rally. The recent price action mirrors that setup, with the index now approaching a green breakout zone. Analysts suggest that a confirmed move above this zone could align with the start of an extended bull phase for altcoins.
