Bitcoin and ether gain 8% while altcoin open interest drops 15% amid a shift toward large-cap crypto safety.
Bitcoin and ether are the sole gainers in the CoinDesk 20 as traders pivot to large-cap cryptocurrencies, leaving altcoins behind. Bitcoin has risen roughly 8% over the past month, while altcoin open interest has fallen about 15%, reflecting a flight to perceived safety in major tokens.
The broader crypto market shows a cautious tilt toward bitcoin, with rising futures open interest and steady implied volatility. Meanwhile, altcoins like XRP and SOL face leverage-driven pressure, and metrics like CoinMarketCap’s Altcoin Season index slipped to 42/100.
Analysts attribute the divergence to bitcoin’s integration into institutional infrastructure, including ETFs and collateral use, while most altcoins lack clear value-accrual mechanisms to justify exposure during downturns.
