Some thoughts on Dash's generations, when a masternode collateral moves, it doesn't necessarily imply it was sold. I often see collaterals that are moved and go right back into new collaterals, some people, probably most don't even know you can revoke a MN and create a totally new one from new keys using the same collateral, so they move it instead to invalidate it and start a new one. Also, recently we've seen a lot of collateral move into the so-called HCMN nodes, this is also creating new churn.
Here is a prototype MNOwatch chart that shows the age of protx registrations on our network, this is the average days a MN has been registered on the network. You can see the trend is increasing as nodes are getting 'older'.
Here is a chart showing the age of collaterals according to the date of the transaction on chain. Note with the stair case pattern, I had to rescan the blockchain and sample it as I went to get old data because we were not capturing it in real-time during that period. This chart is highly experimental, hence not published, but I am confident in the data that follows the stair case pattern.
Finally, here are two charts showing the age of HCMN (the damned). You will notice the chart is sharply rising as no one is taking nodes down, we are just adding to them. Also notice that regardless of how we measure them, protx rego age, or collateral age, the charts are the same and that is because people are creating the collats and registering them in a quick order and so far to my knowledge no one is revoking regos and starting new ones elsewhere, so for the time being, the charts are the same.
By protx rego date
By collateral TX date.
The average age of a MN will increase when no one is moving collaterals, or when new collaterals are removed, conversely, it will decrease when old collaterals move, or several new nodes are formed.
The fact that all these charts are rising suggests nodes are fairly sticky and our churn is low. Dasher MNOs are probably focused on the longer term and continue to hold through the volatility, generally unperturbed by it.
