Half a kore a day off of 500 is 36.5% annual return.
With 40 Masternodes. You should really look at other coin with master nodes and their ROI with 40 master nodes active.
Dash has 4.5.k MN and provides 7% ROI. So with 45 MN Dash would give you 700% ROI.
Im just providing feedback, not complaining. Im sure devs will make adjustements so that we have more than 1k of master nodes and still have good ROI.
