You guys looking for better pools.....DigiByte mining is constantly increasing and so is difficulty. DigiByte's block reward is constantly decreasing.....If you like, wait for better pools but they have nothing to do with why you are mining less DGB.
Basic rule of mining ANY coin: "get what you can while you can" I know it sounds harsh but, mining rewards are not designed to go up over time and if they do, the price usually goes down. Find a pool your happy with and stick to it, pool hoping won't earn you more coins and it tends to piss people off. I've been mining DGB since it was announced. If I want more, I'll add more hash. That's how it works.
