I don't think there is any "passive" income in YouTube or creating something. Passive income flow is owning for example 20% of a farm which pays you out a share of their income every year.

This being said, don't make it complicated. The last 10 years, putting your savings into FAANG was enough, and the next 10? Well, I am 3 years in BTC and it paid me well (2019: +60%, 2020: +350%, 2021: +80%).

Don't read Twitter, HackerNews or any other social media site regarding finance. Or at least, follow 1-2 people who know what they are saying. Stay otherwise away and make money.
