With a single leader we have a centralized system. I would imagine, given BCNext's views on centralization he/she/they are slowly contributing less and less as others do more and more.
Exactly. He mentioned that at some moment in the future he would disappear completely. U'll get the secret phrase that opens the genesis account, everyone will be able to play a role of "BCNext".
I hope there are NO outgoing transactions for accounts with negative NXT!!!
Can you send anti-NXT from the genesis account to normal accounts?
what would such a collision of NXT and anti-NXT produce?
Try it the other way around: Send NXT to the anti-NXT account and see what happens... ;-)
