Ohhh, That is true though, I have heard someone said this before.If you are talking about survey it's all depends on your location so if you reside in top tier country you can make a fortune through survey but for low tier country it's going to be hard
I reside in Africa, a low tier country in Africa, maybe that is why I do not fancy surveys because the pay are usually crumbles, very small and it's not worth the stress.
