After offloading a large amount of your coin, what more motivation is there to continue development?
I've been involved with Incakoin for quite a while already and I strongly doubt that what you described is what is going on here.
The coin has been around since 2013. Given all the other coins that were born and died, Incakoin is doing fine even with the low volume. It's still around !
Madross is the current dev, however what he's selling isn't his own NKA. And we have plans.
doing this we have worked out that we can sustain a steady marketing push over the next 10 months and as the price of incakoin slowly but steady rises over this time our advertising funds will grow making for a far greater reach.

As you can see, this address has 100M NKA in it, and I expect the NKA being offered in OP to be among these funds. I really think the sale is legit and not hurting a coin's community.
This coin's price goes up and down, and stakes 9% every 35 days. It's running well for years and kinda fun.
I can most certainly help as an escrow here, as I have a synced NKA wallet.
