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.
If the developers started allowing 700% ROI for Masternodes I would be investing somewhere else as that kind of dilution would be extremely detrimental. The ROI will no doubt be assessed and scaled with the growth of KORE. The current ROI is extremely good based on current uptake.
