you must search for a faster pool.
you get more dogecoins.
I started also with a smaller pool and had maybe 0.5k coins a day
now I am mining on fast-pool.com and have 2k a day with only 140Kh/s and let this running for only 12 hours.
just saying but that pool is great.
they have new server upcomming.
just try and you will see that this pool is better.
