Haven't been too involved into taking and giving loans because I never needed loans while never lent to anyone because I hardly trust anyone in this crypto industry to be honest and because of the anonymous nature of Bitcoins.

If you are interested in giving loans and earning passive income then the best place I know is a section of this forum - Lending Section.

But, before you give out loans make sure you take enough collateral from them and verify that the collateral is worth giving the loans and you might see some threads there to get an idea how lending works and what are the usual interest borrowers pay.
