why am I getting only 50 KH/s

I think I got over 1 MH/s on bitcoin mining when I attempted it

Thats because dogecoin uses a differant algorytm then bitcoin. However, your card shoudl be more powerfull
I made a dogecoin faucet which gives you between 20 and 200 DOGE every 4 hours, you meight be intrested intro adding it to your topic

when you said between 20 and 200 I haven't thought I would get 30

thought it would be somewhere in between

Haha, better luck next time!
