Bitcoin's price is highly volatile due to factors like market speculation, low liquidity, and news about regulatory changes, security breaches, and technological advancements. Public sentiment, economic conditions, and market manipulation further contribute to rapid price swings. Additionally, Bitcoin's fixed supply and varying demand, alongside technological upgrades and halving events every four years that create supply shocks, lead to significant and frequent fluctuations. Despite this volatility, the overall price trend has been upward sloping over time.
