bitcoin moved passed CPU minung in 2010-2011
it then moved passed GPU mining in 2013

now its ASIC mining using special hardware, where the network has 2million asic units running. and just one asic is about 10,000 fastr than an average PC CPU

these days solo mining using a PC. is 1 chance ever 2600 years at current difficulty. and becomes about twice as hard every 3 months

your only chance now is not to solo solve blocks but to have an asic or a few asics and be part of a pool that work together to find a block solution and have a share of the reward.

in short. sorry but the security has movd beyond hobbyists running a pc in their home. now its moved onto expensive equipment that does things more efficiently

As much as I know there is no easy or average way of solo mining. It is very tough and so I will suggest you to go for CPU,GPU or hardware mining. They are pretty easy.

When I was a newbie a try a lot of options to mine using my computer but I didnt earn a single cent. Try to earn from trading instead.

You're kidding right?. Maybe you should have research more why it is inefficient because nowadays, the network are drastically increasing because of this ASIC miners. With you mining with your PC, you're like waiting for something that will never come in your entire life. It would take you years way beyond your limitations. If I were you, I would begin again to know more about Bitcoin because as what I can see is that you are lacking in it. How does Bitcoin operate and why was it created, maybe you should research that first.

I am fully agreed with @pooya87. I think he has explained the full process as it is in actual. You can follow his opinion to know the actual background.

In crypto currency mining is the big things that affect many things based on this people who are solo miner they also get benefited because they are also expensing money if there is not they won’t mine in solo so of course they give some facilities but not like giant miners.
