Can't say for sure because I don't work in that field, but I use those websites a lot and see many freelancers from India/Bangladesh. My guess would be $2-$3 per hour for basic work.
If you were industrious and took the effort to make your own business and say offer Instagram promotion, you could earn lots.
I made programs for one guy who was cheating on these pay per youtube view websites. That's another thing that you can do.
