# 二元銷毀幣天數｜Binary-CDD

## 指標概念

二元銷毀幣天數是**調整供應－銷毀幣天數的衍生指標**。

考慮了在利息期間銷毀的幣天數是**多於還是少於長期歷史平均水平**。這提供了一個關於大量和/或舊比特幣的消費行為相對於歷史數據是否重要的​​觀點。 

二進制 CDD 將返回 1 或 0： 

* 返回 1：當測量的供應調整 CDD 大於長期平均值時。 
* 返回 0：當測量的供應調整 CDD 小於長期平均值時。 
* 當值 1 或 0 在很長一段時間內保持一致趨勢時，二元銷毀幣天數特別有用，因為它表示長期持有（趨勢 0）或增加支出（一致 1）的趨勢。

## 指標如何衡量、計算？

二元銷毀幣天數通過測量長期調整供應－ 銷毀幣天數平均值來計算的，並檢查當前值是高於還是低於該平均值。高於平**均值將返回值 1，而低於平均值將返回值 0**
