I have just joined a new signature campaign few days ago,and in that the earning potential 0.12btc per month and i do believe i can make that maximum posts allowed to reach that payment because not many posts required,150 in a month,so i will say thats my earning plus,doing some currency exchanges with some users here and some giveaways and bointies,i would say now my montly income from this forum is 0.2btc.
Wow I'm jealous that you are able to earn that big amount monthly. Unlike me I'm just able to earn 0.0084 bitcoins weekly and if I will going to compute that monthly it would be 0.0336 for my rank. But that is fine with me because I have my own full time job and that is able to cover me all my expenses in my daily life.
