signature campaign provides a good passive income, but at the moment I'm not following any of the signature campaign. Well, it made my income be reduced, but I'll keep trying to get a passive income. sometimes I also play trading to get it, even though sometimes the results are not what I expected
income is not "passive" if you are working for it and spending lots of time. and since signature campaigns needs you to spend time and post it can not be passive income unless you are cheating and doing copy paste kind of thing in which case you will get caught and your passive income will be closed down

When you have work and you are working hard for it then you are not going to spend your all time to work with campaign and since you are in signature campaigns you will not need more time to post 5 post per day is okay depends on your campaign and when you are student then that's enough that you are going to called it passive income.
