Hello everyone. I am new to mining and have a few questions.


I have recently put my PC towards mining.

Stats are  ~

Processor Intel® Core™ i7-4770 CPU @ 3.40GHz, 3401 Mhz, 4 Core
 
Physical Memory (RAM) 8.00 GB
 
NVIDIA GeForce GTX 770 ( 2 cards )
 



I feel like I have a pretty good machine, its not meant to be a mining champion or anything, but I wanted to mine coins with it hoping to make a buck or two.  Yet when I am leaving it to work for overnight or during the day, it only makes few cents.. Currently using coinking.io for pool. Ive tried several different script coins and all have same extreme-low income ( Ex. Doge, RZR ) . I have yet to make more than ~5 cents in 12 hours of work, on any coin . Im trying to understand what I can do to receive more profit, because my electricity this month went up 20$ and I did not even mine 1$ of coins.. My machine is putting in a lot of work for very weak rewards. How to make more money for the electricity im using ?  It doesn't make sense to me that I'm losing money rather than making at least a bit, my machine put in a lot of work this month and I have less than a dollar ?
