That'll be a great example of community work. Someone got an idea to share coins with dev. I think it's fair. Let's do 10% development fund which will be under control of new dev. He could do all job himself or pay someone in Nfd for help or whatever.
I suggest paying each stakeholder 0.9 NFD for each 1 NFD they would have gotten if NFDcoin hadn't been a scammer. The dev group get the other 0.1 NFD
(90% to original stakeholders) + (10% for the dev bounty) = 100% of the original NFD coins
Pay ALL original stakeholders 0.9 NFD for each 1 NFD they would have received.
