Average Inputs per Transaction shows the mean number of inputs used by transactions included on a given day. It is the canonical input-side baseline in this family, so it describes how many previously existing outputs the average transaction had to gather rather than how much BTC moved.
A rising series means transactions are becoming more input-heavy on average. A falling series means input-side structure is becoming simpler. It is most useful next to Median Inputs per Transaction and Inputs per Transaction (P90), which show whether the move is broad or concentrated in the upper tail.
The main limitation is that the mean can be pulled upward by a minority of large-input transactions. A higher average does not by itself mean the typical transaction changed. That distinction is exactly why the median and P90 variants belong beside it.
