Right, because at the end of the day we still need to exchange our BTC to fiat before buying something that's why we cannot make it as primary currency since this is not supported yet by most of the country only El Salvador is the one who do this but they still make USD as their main currency and bitcoin is option only. But we shouldn't lose hope as this adoption is started by on country maybe in future another announcement came that they will also make it as their legal tender but let see which country will adopt next.
