First of all i am completely new to Monero mining. Why do i want to do it? I have some solar Panels and way too much energy especially over noon which i cannot use, so normally i "donate" that to the electricity company.

Okay so i have monerod and p2pool running on a VPS i rented for my blog etc, so i dont need to run that on my low power 24/7 Intel NUC at home.

I min now with my Laptop which does about 2,4kH/s and with my Gamin PC which does approx. 4,6kH/s.

I see that the miners get new Jobs from p2pool but okay i dont got any share till now (whats a share anyway).

So what i like to know: do i already contribute to the Monero Network right now or is the computing power wasted? What would be a shame.

Second question: I am mining on the mini side chain, do i have an chance to get a revenue with that setup, so with quite low Hashrate under 10kH/s and that also only for approx. 8 hours a day? Or is it simply useless what i am trying to do?

My goal is simply to get a bit of monero out of my computing power to may cover the 2-4€ hosting costs of one of my VServer.
