~1000 people has about 50% of all bitcoins.
1) Has nothing to do with the discussion
2) Citation? We dont know that
3) Even if it is true it doesnt undermine bitcoin security and decentralization of the mining network
4) Is still not a reason to promote junk coins like NXT
If you buy 90% of all nxt's, security and mining (forging) will be fine.
NXT has many features and more perspective than other 99% altcoins.
