Thank you for your reply. There are many scam site making people fool. I want to know is there any site where I can start mining for free?
There are some cloud mining sites which promises bigger return but you have to invest first, however you will not get profit as promised by them and most of those cloud mining sites are just ponzi like this btcminer.Talking about mining with your computer, you can try freebitco.in browser mining, you might not earn significant amount and your computer might brust at some point. But they are paying few satoshi for your CPU power, I think its only good for fun or to get idea how browser mining works.
You should learn crypto trading rather than spending time to find some sites where you can make free bitcoin. You can't make free bitcoin these days...
