Large institutional trades or whale movements detected on-chain might signal directional intent. Broader equity market performance, inflation data, or geopolitical events can also shift risk sentiment and crypto demand. Technical levels and support or resistance zones may prompt algorithmic trading. Social media sentiment spikes, exchange inflows or outflows, and competing crypto narratives could all move the needle on Bitcoin's price action within that four-hour timeframe.
