All I have to say is that it's near-impossible to make something perfect from the beginning. Through trial-and-error you can easily discover what needs to be tweaked to fit the environment. If you think changes need to be made to DGC now is the time while the network is small.
I'm withholding my vote because i don't mine and don't understand entirely why this is up for vote, though i'm learning toward "no decrease" along with the above posters. As it seems, decreasing mining rewards would dissuade multipool users, though at the same time it would unfairly give those already invested in DGC a much higher return on their holdings, which I don't agree with (unless i'm mistaken on the details). If you want to update your original post with network stats and your personal thoughts on how it's suffering, i would love to read them. Or maybe, hold a poll with all the different options available to us, but really, I doubt there's much to be done to avoid network-hoppers, other than the slow and steady success of DGC to attract miner-loyalty, even through multipool's abuse.
i mean hey, more cheap coins for everyone else i suppose. as always, thanks for involving us
