Join a signature campaign when your account goes to full member or upwards. But do not spam, you'll get banned and that's not worth it. Make constructive posts only and you'll benefit from the forum.
Thats right you can earn bitcoin through joining signature campaign especially when you have a high rank acount but if you decided to begin in the first place then you must rank up your account to have a bigger profit in joining signature campaigns just remember not to spam.
This is the only better way to earn Bitcoin through joining signature campaign because it's free to join depending also on your rank in the forum. Better to check also your account first before joining signature campaign, if you have a good quality posts automatically you be hired in the campaign. Avoid also spamming with a short reply like thank you,ok, I like that, +1 and whatsoever.
That's the most famous job available here in bitcointalk and most are taking advantage of it, if you are a newbie or having a low rank I don't think that it's good to join a signature campaign, spamming is unavoidable when you are just starting and want to reach the quota, sometimes others even cheat, paraphrasing sentences and sometimes others too make short posts... I suggest to just find jobs in the services section, that way they will earn few cents..
Newbies should just stay in faucets until they learn everything about bitcoin because without knowing all that they wont be able to do any constructive posts and without constructive posting they wont be able to stay in a campaign.
You don't need to be bitcoin pro when you start posting here.
I think discussing on this forum is even better way to learn about bitcoin than faucets.
Because faucets doesn't really teach anything, all you see in them is irrelevant ads that won't teach anything to you.
But on this forum you can find many informative posts and if you don't know something you can ask and learn.
That's right, joining signature campaigns are not only for gaining money on purpose but this thing could also help you developed your knowledge on thing related to Bitcoin or in Bitcoin itself. This forum have lots of information you can learn it as you read the opinions and reaction of each member which is very good, maybe some are just spamming but. Lots of reputable members are here to answer or help you if you have question that haven't been answered. But as of now I think question already been asked for how many times.
