Is there a user who has made a total of 1bitcoin in signature campaigns alone , not investments but payment from posting and being paid.
I'm sure there are many of them that earn that amount but may took a long time depending on the rank and campaign they are involved in. Currently, there is a campaign that pay 0.04/week which is Fortune Jack and this campaign run for quite some time already so the people who are under this campaign in the beginning would have already earn more than 1 bitcoin. Few years ago, campaigns pay quite big because bitcoin price is not that high and as bitcoin price goes up, they would reduce payments because it would be expensive for them to continue to pay the same rate with higher value in fiat.
If you are looking to earn 1 bitcoin through posting then you can reach that eventually as long as you continue to post because your pay would be bigger when you rank up. You can also try to join social media campaign so that while earning in signature campaign, you can also earn in social media campaign. In this way, you can reach 1 bitcoin in a short amount of time compared to earning in signature campaign only.
