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?
What is not written here in the content of this topic, may be a consideration that makes countries not make Bitcoin a legal tender.
El Salvador has received many reprimands for implementing the Bitcoin system as legal tender. Even they have recently been rumored to have agreed to the IMF's request regarding Bitcoin because El Salvador needs money.
The implementation of Bitcoin as legal tender in certain countries only makes the country appear different from their financial system or just legitimize it. As long as Bitcoin is not banned, Bitcoin as a currency will have no effect even though people need to convert it into fiat.
