There's a very simple yet highly effective method for predicting BTC's future trend:
It's by comparing it to the US stock market.
I've clearly marked this in the chart. The red boxes indicate potential turning points in the US stock market.
The bottom line represents the US stock market, and the blue line represents BTC.
For example, around October 2023, the US stock market fell for 10 consecutive days, while BTC rose steadily, experiencing a significant surge. The same pattern occurred in May 2025.
Conversely, the same applies to BTC's corrections. Of the three red lines, the green line represents the US stock market's upward trend, while BTC is falling, followed by another significant drop.
The recent decline is also very evident; the US stock market has been rising for many days, while BTC has been trending downwards.
