- •The monthly RSI trend has flagged tops in 2013, 2017, and 2021
- •The indicator isn’t perfect, but its history is notable
- •It’s a tool worth watching in the current market cycle
In the world of crypto, where hype often clouds analysis, one indicator has consistently stood out: the monthly RSI trendline on Bitcoin. Since 2011, this line has quietly warned traders before some of Bitcoin’s biggest market tops.
Whether it was the sharp peak in 2013, the blow‑off top in 2017, or even the first 2021 rally (which many consider the true top), this Bitcoin RSI trend has shown a downward slope before each correction. While it doesn’t act like a crystal ball, it’s proven to be a strong early warning system.
The Relative Strength Index (RSI) measures the speed and change of price movements. When applied on a monthly scale, it reveals long‑term momentum shifts. The descending RSI trendline has flagged overbought conditions even when prices were climbing rapidly.
Could It Signal Another Top Soon?
As we move deeper into the current cycle, this RSI line is once again catching attention. Bitcoin has rebounded strongly in 2024, and many are watching closely to see if this same trendline will mark another top.
Currently, the RSI hasn’t crossed the downward trendline yet—but it’s getting close. If Bitcoin continues its rally and the RSI nears this historical line, it could suggest a turning point.
This doesn’t mean the market will crash the next day. Instead, it’s a reminder that even in a bull run, certain technical indicators deserve respect. Bitcoin RSI trend isn’t perfect, but its past accuracy makes it a valuable tool in any trader’s toolkit.
This line has been flagging Bitcoin tops since 2011.

The downward slope on the monthly RSI has nailed 2013, 2017, and even the first 2021 peak (some argue that was the "real" top).

Why Traders Still Trust This Line
Crypto markets evolve, but human behavior often stays the same. Greed, fear, and euphoria still drive cycles. That’s why time‑tested indicators like the monthly RSI trendline remain relevant.
By watching this trendline, investors can make more informed decisions. Whether you’re a long‑term holder or a swing trader, it helps to understand when the market might be overheated—even if prices are soaring.
