gg2u: which offerwalls are worth the time and effort?

Hi guys, any tips on how to earn gg2u coins?

Apart from hideout, offertoro games, yoursurveys and opinioncapitals, do you guys have any other options that you guys regularly use?

Also, for the offetoro games, I only earn 2-3 dollars for the game offers, do you guys think it is worth it? And did you guys have any game resources to help you get by quicker?
