# 調整供應－銷毀幣年數｜Supply-Adjusted CYD

## 指標概念 

調整供應後的CYD，說明了總供應量的幣天數累積對銷毀幣年數指標的影響。 隨著更多比特幣的發行和網絡累積的幣天數越來越多，銷毀的幣天數的下限將隨著時間的推移而增加。

# Agent Instructions

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://glossary.bshare.io/metrics/xiao-hui-bi-tian-shu-coin-days-destroyed/diao-zheng-gong-ying-xiao-hui-bi-nian-shu-supplyadjusted-cyd.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
