But reducing the collateral from 1000DRK to 500DRK, wouldnt secure the network from sybil attacks since bad actors could acquire the same percentage of the masternode network they could before. Meaning a network with a 1000DRK collateral and 1000 masternodes is just as secure as a network with a 500DRK collateral and 2000 masternodes, is exactly the same thing we wouldn't gain anything. The important thing is to increase the masternode count while keeping the same collateral, that really improves network security.
