Thanks for the explanation.

So in DPoS will there be no coin age requirement?

If coins are not burned, then the same input that staked the current block, would be eligible to stake the block after?

Will the preselected validators nodes, be nodes ran by yourself and others on your team?
If so, as the network grows and matures, would you be looking at a way to address this and allow the network to be more decentralised?
