where i can invest my money to bitcoin or other crypto that i received monthly profit.?
I'm sorry to burst the bubble for you but there's no such thing as passive income that is truly legit that I know off. Perhaps you can offer loans here in the community in this section:
Lending, and that's the closest thing you can get passive income, but it can be dry for months or you can have many people availing of your loan services. But everything has risk, just be careful of people who you dealing with, specially newbies or people getting a loan without any collateral.
That is the thing with life! Everything will always come with its own risk but like you said, except you really have to put somethings down for what you want to do, there is actually nothing as passive income most especially for people looking for it the freeway.
Because of things like this, a lot of people have lost even more by trying to find some passive income through Ponzis, HYIPs, and closely related stuffs, and at the end, they just lose more than they could even imagine. The best thing is that, for anyone that cannot render a service or work in a way for it through some activities, should better just hold if they do not want to end up dancing inside fire.
