VanEck’s MarketVector Crypto Heat Index has triggered a buy signal for the first time since early April 2025, according to Martin Leinweber of MarketVector Indexes, a subsidiary of asset management giant VanEck.
The MarketVector Crypto Heat Index is a data-driven “thermometer” for the crypto market, showing when it is undervalued, neutral, or overheated. Unlike fear-based sentiment gauges, it uses structural and technical signals plus moving averages to trigger systematic buy or sell alerts as the market shifts between these zones.
With a reading of 16.8%, the MarketVector Crypto Heat Index has entered deep ‘Undervalued’ territory. Leinweber notes that the index’s proprietary moving averages have just crossed into bullish territory, interpreting this low valuation as a signal to accumulate.
“Breadth stabilizing. More constituents outperforming Bitcoin. Signs that capitulation-level sentiment may be behind us,” Leinweber wrote via his official X account today.
“For investors still underallocated to crypto, this could be an opportune moment to reassess portfolio exposure rather than react later to price momentum. Sentiment appears near cycle lows,” the analyst stated.
Matthew Sigel, VanEck’s head of digital assets, reposted the analysis, saying that their proprietary breadth model triggered the first bullish signal for Bitcoin in months.

VanEck has previously highlighted Bitcoin’s potential for a rebound in 2026 following a period of underperformance. Analysts at the firm have noted that Bitcoin’s four-year cycle suggests recoverable performance this year amid improving liquidity conditions.
