Because of curiosity about the bitcoin and other coins while searching on google I found out this forum too and also there are a lot of people wearing their signature and avatars so I got curious and want to have this too but the main problem is the merit so I earn hard to get this full member rank during my member rank experience those banners and signatures are paid so I explore more and want to join soon at this kind of signature campaign and right now this is my first campaign which is glad that helps me to earn bitcoin.
You can earn your money by taking part in all contest campaign in the forum.
Selling your various services can make you to earn money from the forum.
Participate in a bounty campaign can make you earn money weekly or monthly due to your participation in the signature campaign forum.
Also with the help of bitcoin talk, I have now knowledge with the Gambling and Trading but most of the time I go to the services and waiting for some additional jobs aside from the signature campaign.
Many are on signature and bounty campaign because it is easy to do if you have a good rank here and you are a good poster you can join any campaign and if you choose the right project to promote you are good to good, the bounty campaign is an open category if you are a writer you can write if you are into social media you can promote there, you just follow the rules of the campaign where you are in.
Even there are a lot of signature campaign still the job of the campaign manager is still choose the best member to join on this campaign, sometimes merit doesn't matter even not get the minimum of 5 merits just to join on some campaigns, because if they know you are a good and have a constructive post there is a chance they still accept you.
