As i understood the cost to run a masternode will be 1000 DRK .
1000 DRK is way too high, i understand you ambition but it would eventually prevent a healthy amount of masternodes.
I would host masternodes worth 2000 DRK, i even have the option to provide different IP geo locations, if one masternode costs 1000 DRK to run i can only host two with my budget. NSA can host thousands!!!!
Please consider that there indeed should be a monetary hurdle but it should be considered really, really carefully. Because probably the advantages outweight the disadvantages from lowering the monetary hurdle.
I really want to urge you to double think about that! 150 - 500 DRK should be much enough to host a masternode!
