So, after completing successful update and comeback, there will be huge pump and then dump. Nothing will change, because all people are same. Just think about this, that someone influential will have interest in pumping this coin again.
Only time will tell us if people will still be motivated after the update. But I really hope that the community will not just stop there and continue improving Riecoin and propose new services for it.
And sure, who knows if some dude wants to create a "Bitcoin Constellation" shitfork like they did for Primecoin. Maybe Zapple could set up a system which prevent whales from pumping or dumping coins, although in another hand, everyone should be free to make any order it wants.
