I've thought about generating passive income the fastest and smartest way. I realised it's never 100% passive. For example, investing in crypto / stocks would also require you to study and execute the trades. Investing in a property would require you to study the rental yield, managing the property etc. So it goes back to what lifestyle that you want to create in the long term? What's your passive income goal & start building strong asset that could take care of you. Then take it from there
