While i aggree NXT 2.0 need to happen at some point in time to address the scalability issue (i think that's the biggest problem right now).
It is clear that scalability is not an urgent problem looking at transactions load right now.
It seems like this change is being pushed maybe too fast, and to make possible an ICO.
About the ICO :
I wouldn't mind personally a slight devaluation of my coin to attract new investor, i still can't get behind it.
Because a second ICO go against everything that cryptocurrency stand for. Playing with the total supply of a coin is a big NO for me.
And like Devlux said, it would scare new investor anyway. Because if we do another ICO, why not another one when things run out.
It would taint NXT forever and it would impossible to get back up from that. (It is NOT tainted right now, even with some people saying it)
THis ICO would very probably a very big fail. People like invest in new things, not old one with a twist.
If we want to get funding, we need to find another way than playing with NXT supply.
I suggest another coin on top of NXT, like some coin are doing on top of ethereum (like LISK or Augur ). After 2.0 it should be easy to create this coin.
This coin would need to be differenciated from NXT of course and have another purpose.
