Sum Coin Age Distribution (SCA Distribution)

Definition
Sum Coin Age Distribution(SCA Distribution) shows the distribution of Long-Term Holder and Short-Term Holder with UTxO data. It is similar to UTxO age distribution but weighted by alive days(=age of each UTxO) to highlight long-term holder's distribution. Each field is calculated as the sum of the products of coin unspent transaction output alive days and its value in a given period, divided by their sum. 
P(X=[ai,bi))=∑u∈utxoslifespanu∗valueu∗I(ai≤lifespanu<bi)∑u∈utxoslifespanu∗valueuP(X=[a_i, bi))= \frac{\sum_{u \in utxos} \text{lifespan}_u * \text{value}_u * \mathbb{I}(a_i \leq \text{lifespan}_u < b_i)}{\sum_{u \in utxos} \text{lifespan}_u * \text{value}_{u}}P(X=[ai​,bi))=∑u∈utxos​lifespanu​∗valueu​∑u∈utxos​lifespanu​∗valueu​∗I(ai​≤lifespanu​<bi​)​
Interpretation
SCA Distribution is similar to UTxO age distribution but weighted by alive days to highlight long-term holder’s distribution in different ranges. If the long-term SCA Distribution ratio increases, then it could be interpreted as the coin's future value is greater than the current value.
The range of SCA Distribution is as below
Less than 1 Day
1 Day to 1 Week
1 Week to 1 Month
1 Month to 3 Month
3 Month to 6 Month
6 Month to 12 Month
12 Month to 18 Month
18 Month to 24 Month
2 Year to 3 Year
3 Year to 5 Year
5 Year to 7 Year
7 Year to 10 Year
10 Year to Infinity
