Bitcoin's price volatility over a 48-hour period has been attributed to a mix of macroeconomic factors, regulatory news, and significant market movements by large holders, according to a report by Chainthink. The report emphasizes that Bitcoin's 24/7 trading environment, its relatively low market capitalization compared to traditional assets, and the absence of comprehensive regulation contribute to its extreme price fluctuations. A recent case study highlighted in the report shows how a rumor regarding potential regulatory changes led to a sharp 13% decline in Bitcoin's price. This drop was exacerbated by cascading liquidations and strategic movements by large investors, commonly referred to as whales, illustrating the sensitivity of the cryptocurrency market to speculative news and large-scale trading activities.
