The GPT site is one of the sites where users can make money online and for free, just by completing light tasks. So a GPT site will pay users to do something like complete a survey. complete offers, *********, read emails etc. Although there are some advantages of GPT sites, such as many ways to make money (not only surveys), cash back, bonuses for new members, contests and sweepstakes etc. but unfortunately most GPT sites choose the territory or country tier, so users from developing countries will find it difficult to make maximum money.
