NODE is on that list, that's why it's worth trying to save it.
Pay-off if successful would be substantial!
This is the reason to try.
My suggestion would be do a 4:3 coin swap (exchange 4 old NODE for 3 new NODE), then use the remaining 25% to pay dev and marketing costs. It's an opportunity for a hungry ambitious dev with enough skills to revive the chain. Nobody expects people to work for free. Could even add an ICO element like lisk::crypti to generate funds, but imo that isn't the best option, Lisk devs set a very bad example now of what happens when clone devs make millions before they've done anything (I.e. they get lazy and go on endless trips/holidays).
I guess any dev who attempted a NODE reboot can set their own parameters though chances of success would be high, risk to the takeover dev is very small, just try and revive the chain. Realsilk isn't around to complain!
Even if swap is 1:1 you might not get much more than 50-60% coins back. Many people deleted keys or not paying attention. Silk may still have 20% or more...
Problem is where to get a developer who can and want to revive NODE. If Silk can't or doesn't want to give the code to anybody.
afaik Silk's identity was known, might be wrong about that though, but if he is public someone could contact him. He can't really refuse a genuine attempt by investors to salvage this project they helped fund. As for finding a competent dev, the first task might be finding and incentivising a project leader to start things off. Pool of possible devs is a lot smaller than pool of potential project leaders. Key is making it worth their while. For that there's obviously the Lisk example of what can happen to people who dream BIG, afaik Max from lisk isn't a dev himself, more of a project leader organising people and tasks - he's a fiat millionaire today! That's what NODE needs now, a project leader willing to revive a failing project with top 10 potential, which node definitely has/had.
