I remember leaving one campaign because of a reputation issue, Other than that money is not my consideration not even the number of posts I exceed my post quota sometimes, I just want to be in a campaign where the project I'm promoting is reputable the manager managing the campaign is easy to deal with and the campaign has the potential to last long and so far the current campaign I'm in has all the criteria I'm looking for a campaign.
It's a case-to-case basis for every participant and could be money, number of posts, and reputation. but if you're going to switch from one campaign to the other you better be a good poster and someone who can get into the campaign easily.
I thought money is not your consideration, so why you are making sure that your post exceeds to your quota? The logic behind is because some threads or replies can get deleted and if we only post 25 per week (most sig campaigns minimum) we can get short and we may not get paid. You also ensure that you are in a reputable campaign manager so that you can always get paid.
Lastly, you want a long lasting campaign so that you can continuously earn a crypto. I believe that this is also the dream of many campaign participant because sometimes a new campaign can come rarely and then applying on it is also not easy. We always need to be on time to have a better chance of being accepted.
