This chart shows the percent of circulating supply that has not moved in at least 1 year. This data shows what percentage of long-term holders have kept their bitcoins.
This index has a negative correlation with price. When prices fall, holders are reluctant to sell and the index starts to rise. Once the price has risen enough, some of these holders will start selling their bitcoins, which causes supply to increase and prices to start falling.
The linear correlation in the correlation oscillator indicates the negative correlation with R = - 0.9. For a better understanding, a bitcoin chart is drawn next to it and the peak and trough points are marked.
