Bitcoin often dumps sharply due to a **mix of macro, market structure, and sentiment factors**. Rising interest rates or strong economic data can push investors away from risky assets like BTC. Large holders (“whales”) taking profits can trigger cascading liquidations in leveraged futures markets, accelerating the drop. Regulatory fears, ETF outflows, exchange issues, or negative news also hurt confidence. When key technical support levels break, panic selling increases as stop-losses are hit. Finally, crypto markets are highly emotional and thin compared to traditional markets, so fear spreads fast, making sell-offs deeper and quicker than expected.
