Bitcoin’s volatility in 2025 exceeds other cryptocurrencies due to its dominant market position and sensitivity to macroeconomic factors. Institutional inflows via ETFs amplify price swings, while regulatory shifts and geopolitical events disproportionately impact BTC. Altcoins, often tied to specific use cases, experience more stable demand. Bitcoin’s halving aftermath and mining shifts to AI/HPC further destabilize its hashrate, affecting price. Despite its “digital gold” narrative, BTC’s liquidity attracts speculative trading, driving sharper fluctuations.
