The first thing to do is to do research. Look for legitimate sites that really would pay out. Sites with authentic payment proofs. Not only that but with credibility. The ones that go straight to the points, and after that, never compromise the points. Go for sites like that.
If anyone has ever told you there is this easy way to get money, it's either that person is kidding you or lucky. Yeah, sometimes some people get lucky. When they bump into a business or something, suddenly they would just come out of it blossoming. Yeah, some are really that lucky.
But what I'm tryna say here is that, even if you could get lucky, being prepared to get more luckier isn't a bad idea.
So make sure you really find a good one and immerse yourself in it till you squeeze some reasonable juice out of it. Be persistent, diligent and consistent. Don't ever give up.
