What is best paid traffic source for the niche "Make Money"

Depends on what you promote.

Fb ads works good in this niche. Moreover display and native ads can help you too, but as I said, it completely depends on what you promote.

 

Facebook should work indeed, but they don't allow to promote "get rich quick" or "unrealistic money making online schemes". If you can prove that what you are promoting is legit, they will let it fly.

The same goes for google, it could work there for sure, but it must be a legit product.

Native is used for this, but watch out for all the bot placements.

Display used to work, but it's pretty much dead for now...

You can also try to look for forums, reddit groups, facebook pages and groups ... that are related to your product and establish yourself there - then promote it CAREFULLY to that audience.
