I agree 1,000%! People are always going to stick with what's comfortable to them until it's taken away from them. Real estate and gold are better than fiat to me. I'll commit 100% to bitcoin if I was allowed to use it everywhere.
I agree, investing in fiat is not typically considered a good long-term investment strategy because of its lose value over time due to inflation or any other factors. As you said it's better to diversify investment across different assets like Real estate, gold and cryptocurrencies to protect against inflation and potentially earn higher returns. But consider the risk you will take investing.
