DASH currently has 6.33 million coin supply with ~3400 masternodes.
You need 1k DASH per MN so it has approx. 54% locked down as MN.
DNET currently has 20.71 million coin supply with ~730 masternodes.
You need 10k DNET per MN so it has approx. 35% locked down as MN.
That's some feat considering DNET was only launched 2 months ago.
USP will come according to devs so we'll just have to wait and see.
Creating infra takes time. Definitely needs more helping hands...
That was my point. If masternode payments are only slightly better than staking, number of masternodes will decrease. This strength of the network will be considered as a part of the USP when it comes to the consideration of exchanges like Poloniex. Therefore encouragement of masternodes needs to be a priority.
