The daily price fluctuation of Bitcoin is driven by multiple intertwined factors. Market supply and demand have always been the fundamental forces. The daily inflow and outflow volume on the exchange chain changes by billions of dollars. When the short-term buying intensity significantly exceeds the selling pressure, it often drives the btc price to rise rapidly by more than 5%, such as the institutional buying wave at the beginning of 2023. Meanwhile, the open interest in the derivatives market often remains around 28 billion US dollars, and a high-leverage long liquidation event may instantly trigger a flash crash of more than 3%. The Panic and Greed Index, which measures market sentiment, provides a quantitative reference. When its reading shifts from the extreme fear range to the greed range, prices often gain a rebound momentum of 8% to 15% in the following days.
Regulatory dynamics have an immediate impact on investor confidence. In August 2023, the US SEC rejected applications for Bitcoin spot ETFs from multiple institutions at one go, causing the price to plunge by 9.2% in a single day. On the contrary, when El Salvador announced the acceptance of Bitcoin as legal tender in 2021, the increase on that day reached 12%. The policy stances of major economies vary greatly. For instance, the enhanced clarity of the EU’s MiCA framework once led to a 25% drop in weekly volatility, while the US Treasury Department’s sanctions announcements against cryptocurrency mixers have repeatedly triggered intraday fluctuations of over 7%. Regulatory uncertainty contributes an average of 30% to price fluctuations.

Macroeconomic variables are increasingly exerting a significant influence on the allocation decisions of crypto assets. Bitcoin and the US Dollar Index (DXY) show a medium to high negative correlation of -0.68. When the DXY appreciates by 1.5% in a single day, the probability of Bitcoin falling reaches 75%. The shift in interest rate expectations is particularly crucial. During the period when the Federal Reserve raised interest rates by a cumulative 425 basis points in 2022, the maximum drawdown of Bitcoin exceeded 65%. When global inflation data such as the US CPI peaked at 8% year-on-year, the demand for crypto assets as hedging tools pushed up the price of btc by 22% in a single month. On the day when geopolitical conflicts such as the Russia-Ukraine war broke out, the price fluctuation reached 16%.
Mining activities constitute a fundamental support point. The total network computing power has exceeded 600 EH/s, and the adjustment of the average block generation time directly affects the supply rate. With the new generation of mining machines such as Antminer S19 XP increasing the efficiency to 21.5 J/TH, the lower limit of mining cost has been reduced to 18,000 US dollars. However, mining companies with energy costs accounting for as high as 38% need to adjust their selling strategies when electricity prices fluctuate by 10%. During the bear market in 2022, the daily clearing volume of miners once reached 600 BTC. The upcoming fourth block reward halving will reduce the daily new output from 900 BTC to 450 BTC. Historical data shows that the average return rate in the 12 months after the halving is 430%.
Technological development and unexpected events often trigger instantaneous giant shocks. In 2024, the Ordinals protocol’s innovation pushed the number of daily transactions to a new high of 680,000, and network congestion caused the average transaction fee to soar to $40. The security incident had a severe impact. The expected news that Mt.Gox creditors would release 140,000 BTC in 2023 caused a peak selling pressure of 410 million US dollars in a single day. National-level events such as the Central Bank of Nigeria’s ban on banks providing cryptocurrency services led to a weekly outflow of 580 million US dollars. Algorithmic trading strategies now cover 70% of trading volume. Programmatic sell orders triggered at key support levels can amplify intraday fluctuations by more than 50%. For ordinary investors, tracking the percentage changes in these key indicators helps to understand the short-term trajectory of btc prices.
