According to a chart released today by Matrixport, as reported by Odaily Planet Daily, there is no absolutely effective trading rule when investing in Bitcoin, but many market participants focus on one indicator: the 21-week moving average.

As we've mentioned many times in our weekly Matrix on Target reports, the 21-week moving average has consistently proven valuable over various periods. Investors who pay attention to this indicator are often better able to reassess their positions and risks during periods of increased volatility.

The current price movement may see further declines, but it doesn't necessarily mean the Bitcoin rally is over. It's more like a reminder that instead of being completely swayed by short-term noise, it's better to refer to a few simple, time-tested benchmarks as relatively stable reference points for decision-making.
