For Bitcoin to be adopted as a legal tender, off course it must go through certain processes, but these processes are not ambiguous to say the least. Countries like El Salvador and not so recently The Central African Republic are Trail Blazers in the aforementioned. Looking at it realistically, the merits would certainly alleniate any demerits that may occur. It surely puts innovation where it should be on a pedestal, foreign cash injection becomes and the global phenomenon; inflation can be better managed. What is holding back is definitely from constituted authority, as households and individuals already accept Bitcoin in some forms as a legal ten. What is stopping it's gradual integration?
tender law doesn't guarantee mass adoption, yet it puts pressure on organization and has transparency that the old systems lack. El Salvador and Central African Republic shaped a path for lightning wallets like Chivo ,to help internationally and fully voluntary capital and tourism ,that won't happen in other countries without legal transparency.
afaik still 8% of Salvadorans did transactions with BTC in 2024 but the International Monetary Fund pressure led them to change obligatory approval due to budgetary and uncertainty risks. in the meantime highly Bitcoin integrated markets such as the UAE and Vietnam are profiting without legal tender laws because of directives and true demand fueled use.
So yeah legal tender could hasten the way for change but true acceptance requires to be a custom , it can't be a law only, it needs transparency and integration.
