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
A real form of passive income would be some kind of profit-generating investment or device that doesn't require you to spend any time on it, and would effectively generate value as you sleep, per say. This can take on many forms, however a signature campaign isn't one of them.
