I heard from someone that if you want to earn money without any investment then you should go to bitcointalk. But he also told me to keep alert. I created an account. I am feeling very confused but I am not able to understand anything.
Welcome. But your friend lied to you because he did not tell you how everything works here and how you will go about making money on the BitcoinTalk forum. Even aside from the signature campaigns for you to earn money here, you need to be known by forum members before someone can give you a project to handle here; you are still a newcomer. I doubt if you have already studied the forum rules and regulations the way you suppose, so go and do that before you will think of earning in the forum.
A newbie with only three activities since he registered shows no much concern yet about ranking up in the forum to stand a chance to join a paid signature campaign. If he’s not coming with any services he can render, then he’d come to make money through signature paid campaigns. He must have gone through the many links sent to him by other members of the forum on how the forum works, and criteria’s needed for him to join a signature campaign.
He won’t be given any project to handle because he didn’t say he’s rendering any services that he can offer and get paid for, so he’s likely not here for that but needs to get into a paid signature campaign. I am not sure he’s ready to make that sacrifices yet and willing to develop himself better here. It always sounds very easy until you’re given the avenue to prove your seriousness to achieve that which you want so importantly.
