the forum (bitcointalk.org) is such kind of forum that you are looking for.
yes but you need to have effort if you want to be a profitable here in forum and also knowledge how to earn in different ways cause there's a lot of opportunities here in forum such as selling services or skills and joining in any activities like campaign such as bounty etc. The must is knowledge about currency or any stuff that related in bitcoin if you dont have it then must learn first .best regards
It's not actually a big effort so that will be fine when you are trying to earn some small fractions of bitcoin there. And it's not that hard to answer some sort of surveys so that you'll get paid. I once tried to earn with surveys but I can't remember if they are paying bitcoin today and I also forget those websites where you can have some proper amount of bitcoin. And as always this forum is the best site to earn some btc.
