Get a full-time job and buy the bitcoin on exchange...
Yeah man. Everyone wants to earn Bitcoin online, but it is not easy at all. Just get a job and buy it with your fiat earnings. It is the exact same thing.
Earning bitcoins online is only for those who are not having any good day job. They are supposed to earn bitcoins online to meet up their financial demands. Bitcoins are best to be bought at exchanges if you have money in your pocket and sell them off when prices are high. Online earning has many issues like scams etc. It is always not safe to earn online.
