The priority of this forum is not exclusively earnings, but spreading knowledge about Bitcoin and discussing the ecosystem that accompanies it. So this is not a "get Bitcoin" platform and whoever presented it to you like that has the wrong picture.
Of course, there are possibilities, but before that you have to familiarize yourself with the forum itself, in time you will understand what opportunities it offers. So, learning is the best advice for you.
Earning is one of priviledges in this forum, and forum admins are happy by giving people opportunities to earn something by their contributions to the forum community. It's privilege, not rights, and it's not main purpose of this forum as written clearly in
a welcome message of Bitcoin forum.The purpose of the forum
This forum exists to provide a platform for the free (but ordered) exchange of ideas. If you have an idea to express, then it is probably possible to do it here as long as you follow the rules.
A lot of people come here primarily looking to make money. The forum administration is very happy that people are able to use the forum in order to better themselves; indeed, one of the reasons for Bitcoin's creation was to break the artificial barriers which prevent so many people around the world from attaining prosperity. However, if your attempts to make money conflict with the forum's primary goal of enabling discussion, then you are swimming upstream, and you will not be sucessful in the end.
If you view the forum as some sort of "job" where you complete some basic tasks and get paid, then you will almost certainly be disappointed, and the forum administration will not be sympathetic. If you do make money using the forum, then it will be through innovation and entrepreneurship, not any sort of mindless busywork.
