If you have been into Bitcoin for sometime then you should know that there aren't many well known freelancing sites where a user can earn Bitcoin. The only site that can help you to earn some good amount Bitcoin is this forum because in this forum anyone who contributes information and stuff and ranks up to full member or above rank member can generate some amount of Bitcoin by applying avatars or signatures on his/her profile.
You can also earn some Bitcoin if you have services that you can offer on this forum. For that kind of service you'll have to go to services board and create your thread there. Sometimes there are other tasks that could also help you to earn some Bitcoin on this forum. You can also participate in contests, free raffles, games and rounds to generate some bitcoin from this forum. If you're a hard working person and you give your best to your work then this forum is the place for you.
Many members of the forum are earning substantial income from the signature and avatar campaigns of this forum, but in order to avail those opportunities you will have to rank up to at least full member rank. Once again if you're hard working and at the same time you can contribute good information to the forum then surely you can reach that rank within 4 months.
