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.
