Bitcoin could reach $180,000 in 2025 if key market indicators remain stable, according to Matthew Sigel of VanEck. He notes that Bitcoin typically sees strong performance in the two years following a halving event, with historical data suggesting a potential price surge from a low of $18,000. Sigel emphasizes the importance of monitoring derivatives funding rates, unrealized profits, and retail speculation as indicators of market health, while also projecting a long-term price of $3 million by 2050 if Bitcoin is adopted as a global settlement currency.
