Despite the fact that dollar is devalued and we all know that US is printing it without any backing of physician stuff like gold. We still need dollar and other fiat for our daily living, even BTC value is measured in USD. Gold is still stable and matured market, thats why its has huge market cap. IMO we get over excited in describing BTC, which is not fair.
Have you ever tried to find out that why is inflation rising continuously and what government is doing to tackle those matters? They are just printing infinite supply of notes making them devalue over time and from a long time it was not backed by any asset at all which was just an illusion only.We need fiat in our daily lives and you are right on that point but here we are talking about future investment plans and what do you think i am paying with bitcoin all my expenses? No at this time we need fiat but having vision for future and how dollar have been devalued over time makes me worried and btc enthusiastic.
You said gold is stable and you are right as it has not given any returns in the past 10 years to the Holders and if you want such risky and useless investment then you are free to choose man as nobody restricts us to do so.
For me bitcoin is best and it might not be for you but saying bitcoin is not useful then gold and fiat is not fair and preety senseless according to me.
