I opened the link and currently I'm using btcclicks.com; you can earn bitcoins by viewing the site for a certain time. I haven't withdraw my first earning yet, you have to reach a certain amount in order to withdraw your earnings.

Well, you can earn through legit sites but it don't guarantee you that you can earn as much as 1 btc in just a couple of months. You can refer as many people as you can to earn more but don't just rely on these sites, rank up your account here in bitcointalk and join in bounties available to earn.
