For me, my passive income is by doing my tasks to complete here in signature campaign. This is I think of as of now, since by joining here in any campaign will surely give an earning weekly or depends on the rules. Also, by buying and selling bitcoin were I also earn bitcoin.
That is not really passive income at all, passive income means you dont need to do a thing to obtain your profits, if you need to take some active action to make money then it is not passive.
A short definition of passive income according to Investopedia:
Earnings an individual derives from a rental property, limited partnership or other enterprises in which he or she is not materially involved
As I've seen recently on this topic that there's still someone who misinterpreting the real definition of passive income and uttering the thing that's out of context ( in this case, passive income ).
Doing tasks to get paid ain't considered as a passive income.
