RSI stands for Relative Strength Index. It's a momentum oscillator invented by J. Welles Wilder that measures the speed and magnitude of recent price changes. RSI ranges from 0 to 100:
For Bitcoin, RSI is particularly popular because crypto markets are volatile and swing quickly between extremes. A Bitcoin RSI oversold reading at 25–30 on the daily chart has historically preceded significant bounces. Learning to read RSI signals can help you identify potential dip-buy entry points.
The RSI dip signal is one of the most-watched patterns in crypto technical analysis. When Bitcoin's RSI falls into the 20–30 zone (deeply oversold), many traders treat it as a potential buying opportunity — not as a guaranteed bottom, but as a statistical edge.
Historical examples on Bitcoin: the 2018 bear market low, the March 2020 COVID crash, and the May 2021 correction all saw RSI readings below 30 on the daily chart before substantial recoveries. The RSI alone is not a trading strategy, but it's a useful filter when combined with other signals.
Crypto technical analysis, including RSI signals, does not constitute financial advice. Cryptocurrency markets are highly volatile and RSI signals can fail, especially in trending markets. Never invest more than you can afford to lose. This guide is for educational purposes only.
