I'm trying to approach this perfect number, but I'm more around 10 for now. I also like to diversify in material investment, like silver, gold, collection coins. You never know... And gold, for example, is the only thing that never lost value in the history of humanity. So I think it's always good to have some.

For now, I'm mostly invested in gold and in cryptocurrencies, but would you advise me to invest also in some "classic" stocks?

Thanks for the concise article, and the great synthesis. ;)
