Circulating Supply (BTC) shows the same monetary stock as the canonical supply series, but expressed in BTC rather than satoshis. It is a display-unit variant, not a different supply concept or a separate calculation.
A rising series means more Bitcoin has been issued into circulation, following the protocol’s fixed supply path. It is most useful when supply needs to be read in standard Bitcoin units, especially beside Market Cap and other BTC-denominated views.
The key distinction is presentation. This series improves readability, but the underlying monetary stock is identical to Circulating Supply in sats. For exact native-unit precision, the sats version remains the base reference.
