Obviously, it is not all about high minimum payment but are those sites legit to work on, because they are so many scam sites out there that are out to milk dry the efforts of the members. Sadly, we've had so many people who have worked on such sites, and when it was time for them to get paid, they would dash the hopes of the members.
If indeed, we have such sites with high minimum payout threshold, and I am fortunate enough to render my services, the first thing, I will do is to inquire how genuine they are because it is all that glitter that is gold, even foil paper also glitter. My investigation about them probably from reviews online and google would be handy in this regard. And if they are for real, I can then commit to working for them. But if there is no proof of their legimacy, I woud outrightly decline my intention without thinking about it twice.
