Ok here is what Goldcoin did when they lowered their block reward from 500 to 50. A couple weeks later instant surge to the moon. Of course it dropped back down aftwards but the new baseline was still 10-30x higher. Mind you, this was with a coin most of the community hated. Everyone LOVES Digibyte.

I'm up for a decrease in block rewards. Maybe 2000 or less a block?
Increasing the difficulty of obtaining DGB would certainly increase it's value. I think it would be better that way.
Also, everyone seems to want Kimoto Gravity Well, so I don't see why not. I need to look up on what exactly it does, but it seems like it makes it easier to recover from multipool attacks somehow.
