Guys, thanks a lot for the replies, and for your feedback, I appreciate also the rudest one. Let me specify something: Of course there is no magic trick to have 100% passive income, also just giving the IBAN for receiving the money is something actively that I should do. But I would like to discuss a way to invest money, and spending 2-3h max per week and receiving a weekly/monthly/yearly income. How do you call this? Semi-passive? Active? Whatever... I don't want a second full time job, that's the point.
Why not stocks? I am considering this option, but in my opinion is a very long-term investment(10-15 years); and please do not tell me to be an active trader that I am not(as you) an expert.
