GPT means Get Paid To, so you earn money doing tasks like answer surveys or watch ads
I would like to talk about Cointiply
It's a cassic GPT, you do tasks and earn coins (ratio : 1 coin : 0.001$) and you can withdraw if you have at least 30.000 coins (3$) or you can let your coins and earn a 4.08% annual interest calculated daily, they give interest coins every Monday
