Yes, it was planned from the start as you can see on the block reward schedule included in original post.
Block Reward Schedule
A total of 100,000,000 MTNC will be used for the initial coin supply.
Year MTNC/Block MTNC/Year Total
1 30 17058660 117058660
2 20 10512000 127570660
3 10 5256000 132826660
later
5 2628000 135454660+
The interest rate is dynamic for every masternode，That means more masternodes in network ,the less interest for every masternode.
For example:==> first year :All masternodes compete for 24MTNC(30MTNC/Each block and 24MTNC for masternode interest) for new block outputs.
The last 6 MTMC will be the POS interest.
