Thank you for the guide! Is it possible to solo-mine?
Well, I don't think solo will be profitable at all. Better to join a pool depending on your location.
As a reference I can show you luck with a couple of kh/s: 4357001.392 Days. While the medium size pool total hash power of 2 mh/s has luck of 3572.831 Days and finds around 20 blocks per day. So do the math if you can find a block solo at all

Luck is calculated wrong in most of pools...
I have a worker mining at 1.33 kh/s on my pool with a real luck of 3.590 days which mean that it will probably find a block every 3.590 days. It is running for about 7 days now and has found 3 blocks so far.
So it is possible to solo mine, but I agree that it's better to join a pool because you could end up being unlucky for a long time before you find a block
