BTC Dominance Clears 60.66% as Harvard Exits Its Entire $87M ETH Position

Bitcoin dominance surged to 60.66% this week, marking the first clean break above a key eight-month accumulation range. The move reflects a sharp rotation away from alternative cryptocurrencies and toward the flagship asset, driven by both institutional positioning and fear of altcoin volatility in a macro environment increasingly focused on rate hikes and geopolitical risk.

The narrative inflection point came when Harvard University liquidated its entire $87 million ETH position after purchasing it just three months prior. The Ivy League institution's exit, combined with broader institutional flows data, signals that smart money is consolidating into bitcoin rather than diversifying across altcoins. Ripple's RLUSD stablecoinA cryptocurrency designed to maintain a stable value, typically pegged to the US dollar., meanwhile, posted a new all-time high on-chain market cap of $1.7B, demonstrating that institutional adoption is happening but in a more selective, base-layer focused manner.

Altseason indicators have collapsed. The Altcoin Season Index fell to 39 out of 100, the lowest level in months. ETH traded at fresh yearly lows against BTC, and XRP, despite recording one of its strongest wallet growth spikes of 2026 with 4,300 new addresses added in 24 hours, has seen its market cap compress by roughly $10.3 billion since last Friday on regulatory clarity concerns tied to the CLARITY Act. The crypto market is consolidating conviction around bitcoin and base-layer infrastructure plays while rotating out of speculative alt narratives.

Market participants argue this is healthy regime normalisation after years of altseason excess. Bitcoin at $77,300 offers investors a simpler narrative tied to macro factors: Fed policy, geopolitical hedging, and corporate treasury accumulation (Morgan Stanley's recent 83 BTC purchase exemplifies this). Altcoin bulls counter that dormant altseason can flip rapidly once risk-on appetite returns, and that builder ecosystems on Solana and Ethereum still command institutional interest. However, current data suggests the momentumThe empirical fact that winners keep winning over the medium term. lies firmly with bitcoin concentration.
