NEM for instance has 3000 stakeholders. Taint analysis was used to remove hundreds of sockpuppets and the large scale diminishes any return from sockpuppets.
That I find hard to believe, communitycoin tried to distribute to just 1000 geniune and found that hard to do and reduced it the 500 and checks showed that only like 300 odd where proper users etc so I fond 3000 individuals in these parts hard to believe.
NxT had 20,000+ addresses when NEM was announced. NEM was new code based on a proven (but distribution flawed) concept.
Communitycoin on the other hand has no prior base to attract, has an unappealing unprofessional name and a complicated IPO for what could be worthless coins.
Sockpuppets are more common for obscure coins.
Yes but those complications in communitycoin prevented cheating which is why such a limited number qualified, seems if you prevent multi nicks few can get, therefore multi nicks in other coins seem likely to be extremely common and outweigh genuine individual holders.
