In my opinion, currently Bitcoin cannot be used as a full payment adoption, this is because not everyone, both buyers and sellers, accept Bitcoin. Only a small part and by mutual agreement use Bitcoin as a means of payment, currently Bitcoin is very popular in the world because it is an investment that provides many benefits. I understand that there are some people like you who want full adoption to be used as a medium of exchange but this has not materialized as people prefer it as an investment like gold.
