How to read Bitcoin RSI

One-minute answer: RSI compares the size of recent Bitcoin gains with recent losses and turns the balance into a 0-to-100 score. SafuTrading's full chart uses monthly candles, so it describes long-cycle momentum rather than today's intraday move.

What it actually means

RSI stands for Relative Strength Index. It asks a narrow question: during the chosen window, were upward price changes stronger than downward changes? The result is bounded between 0 and 100.

The timeframe matters. A daily RSI can fall while a monthly RSI remains high because they summarize different sets of candles. The SafuTrading detail chart is monthly and is meant for cycle context, not minute-by-minute timing.

What to look for

Above 70 — Upward momentum has been unusually strong for this timeframe. It means stretched, not guaranteed to fall.
Around 50 — Recent gains and losses are more balanced.
Below 30 — Downward momentum has been unusually strong. It means stretched, not guaranteed to rebound.
Price and RSI diverge — If price makes a new high but RSI does not, momentum has weakened. That is context, not proof of a reversal.

Worked example

A monthly RSI of 78 means Bitcoin's gains outweighed its losses strongly across the completed monthly window. It does not mean Bitcoin is 78% overvalued or that the next month must close lower.

What this cannot tell you

RSI only uses price changes. It does not know about liquidations, holders, news or valuation.
The familiar 70 and 30 lines are conventions, not physical boundaries.
Never compare a monthly RSI directly with a daily or hourly RSI without naming the timeframe.
