Bitcoin (BTC) experienced a major crash towards the end of 2025, ending the year, which was otherwise full of new all-time highs, on a weak note. However, it saw a slight recovery in the first days of 2026, with the VanEck index showing the first bullish signal for Bitcoin since April 2025.
According to the VanEck MarketVector Crypto Heat Index analysis, Bitcoin is showing its first bullish signal since April 2025.
Martin Leinweber, Digital Asset Product Strategist at MarketVector, a subsidiary of VanEck, stated that the MarketVector Crypto Heat Index gave a “Buy” signal for the first time since early April.
The index, which helps determine whether the crypto market is overheated or undervalued, recorded a 16.8% drop and entered the “Undervalued” zone.
Leinweber noted that the index’s characteristic moving averages had recently crossed into the bullish zone, suggesting that further selling pressure was unlikely, and interpreted this low valuation as a signal of accumulation.
Matthew Sigel, VanEck’s Head of Digital Asset Research, also shared the analysis, adding that his company’s proprietary models confirmed the first bullish signal for BTC in months.
Experts also added that historically, “Buy” signals from this index have yielded an average return of 20.4% for Bitcoin in 90 days and 76.7% in one year.
