If Supernet splits from NXT, it'll be Supernet that fails not NXT.
SuperNET is not going to 'split' from NXT. SuperNET will natively implement some functionality that it is currently accessing on the NXT API.
The assets and the fee, dividend and revenue stream structures remain.
Well why is James "rage selling" his NXT?
As was talked on slack, he is emotionally trying to show, that he can dump the price significantly, so this is a protest to core devs. Also consider the price of this millions, now he bids 20K NXT for BTC, no one will buy that, so for now this is just a protest.
A little hotheaded over an API change don't you think? His blackmail attempts don't inspire a lot of confidence in him or his software. Maybe we should just play out this game of mutually assured destruction that he's started and anybody who holds his assets should dump them. A lot more NXTers hold his "assets" than he holds NXT. Let's push the button and see who survives. Hint: It won't be James or Supernet.
No, I think the truth is in remarks from both sides - core devs have made a mistake while changing API and so giving a reason to eveyone not to believe NXT at all and not to build serious corporative platforms on top of it. They should be considered like guys who have largest NXT stakes, so they are feeling technical and economical power (but saying that I am not going to hurt them, I respect their continous hardworking on the core features). And I should say, this facts could kill NXT. Like mentionally-caught parents could kill their child with infinite love.
Second side is James. He is advanced and very creative, open-mind dev of SuperNET, which could be considered like "such large corporative project on top of nxt" which is very useful and important for NXT platform. And after changing API - it fails. There is no matter, whether it is easy to fix or not (this is the argues of core devs, that the fixing is extremley simple). Now his work is failed due to risk of API changing, it will take him more work to fix the code and to put away some technical nxt dependancies.
SO. It is clear, that James is very important to our community, and thus, to a price o NXT, James will not leave SuperNET from NXT completley it is for sure, but this act of selling 20M nxt - is an act of protest and demand for core devs to mention and to respect the users of the core (cause building a systems on top of the nxt - it is also - a "using a system" of NXT). But his dumping... Don't like this to be real dump
So there is no need to talk about is he survives after his dump. I also think, that it is crucial for one man to rebuild the SuperNET, it is crucial for everybody - cause NXT platform and SuperNET - are losing clients and investors both. I think the way of both sides is to respect each other and produce a synergy, not competition.
