I wouldn't give this Dev a penny in ICO money, it would be a final exit scam. We'd get double fucked then. We've already paid for the VTR token.
The only way I see this working would be add 10% to the supply of the new fork.
Edit: Do you think the Dev deserves "your" money after the way he's been with us on this project? That would be seriously taking the piss asking for ICO money, either you belive in the value of your own work and except the VTR token as payment or I really would start to see it as an exit, scam, if the rumours of the the dev dumping his coins are true, then giving a free meal ticket via an ICO would possibly one of the most dumb fuck moves you could ever do in you life time.
