Proof of Stake for Datacoin

Decred implements proof of stake as a Hodler incentive, and I think we need something similar for Datacoin.  Datacoin has no Hodler incentive, which is why so many coins are dumped for Bitcoin.  I was surprised to see that about 50% of Decred coins are staked, which removes a massive amount of loose coins from the market.  No wonder the price is $11 per coin.

How difficult or how easy will it be to add staking to Datacoin?  I was thinking that 10% of the coinbase reward can be given to staked accounts, with 90% going to the POW miners.  In this way there would be no inflation, and we would still end with 2 billion coins sometime in the 25th century.

I would like to use a developer treasury to do this project, especially since the developer treasury could itself then also be staked, to earn income to fund the developer projects.

Any thoughts on this issue would be most welcome.
