Who holds the massive premine?
I see now there was a blockchain swap.
What was the reason for it?
See EagleFlies post:
https://bitcointalk.org/index.php?topic=402667.msg27491441#msg27491441"we switched from PoW to PoS 3 years ago to fix inflation problem and also to prevent attacks. In the past NobleCoin was under 51% attack when we were still PoW coin."
Noble is one of the most legitimate coins out there and was launched and developed extremely fairly, with no premine and a super honest dev.
Even after 4 years it's still going strong and has a very solid foundation.
All it would take is for a few developments to be implemented and everyone would be falling over themselves to get on board.
