VanEck’s crypto heat index flashes first Bitcoin bull call since 2025 bottom
VanEck's MarketVector Crypto Heat Index issued its first buy signal for crypto since April 2025, suggesting an undervalued market.Summary
VanEck’s MarketVector Crypto Heat Index, a data-driven indicator for crypto market sentiment, has signaled a buy for the first time since April 7, 2025, according to Martin Leinweber of MarketVector Indexes. The index registered 16.8%, placing it in deep 'Undervalued' territory, with proprietary moving averages crossing into bullish territory. Leinweber noted that market breadth is stabilizing, with more crypto constituents outperforming Bitcoin, suggesting that sentiment has reached capitulation-level lows. Matthew Sigel, VanEck’s head of digital assets, confirmed this proprietary breadth model triggered the first bullish signal for Bitcoin in months. Analysts suggest this presents an opportune moment for underallocated investors to reassess their crypto exposure before potential price momentum kicks in, aligning with VanEck's prior outlook for Bitcoin's rebound in 2026.
