Thank you LoyceV and bitmover for your inputs.

I agree that you don't need to understand bitcoin to invest in it.
Actually, this is true for every investment: you don't need to understand stock market to put money in it, and you don't need to understand fiat money to hold and use it for your everyday life.

But, this is recipe for disaster: not understanding the things you are putting your money into is the shortcut for an inevitable loss.

This is why I want to have at least a basic understanding on how  things work before putting my money into it.
In addition to that, bitcoin si something of a paradigm shift: it's brand new asset class and you need to think in a "strange" ways to many things you already know: the most important one being the money.

So this is something I want to do: give everyone a little bit of "start" in understanding Bitcoin. As bitmover said, everyone can approach  Bitcoin from very different angles, and be drawn into if by really different aspects: as the average Joe actually doesn't exist I want everyone to  find their "own" explanation in the provided resources.

There's a great responsibility in owning bitcoin. You gain financial sovereignty, but this comes at a cost: you have to understand how you gained it.
Otherwise is another slavery.
