What you think will be very possible in El Salvador because bitcoin is already a legal tender in there so it will be expected that even major sectors will definitely be accepting bitcoin in time. Hopefully, other countries too will start accepting bitcoin after things will be successfully worked out in El Salvador.

McDonald is a very famous food chain so its more likely that if some branches were able to accept bitcoin then we might expect in the long run that other branches too will soon to accept bitcoin. Let's just wait for it and see. I think the adoption of bitcoin has often increased day by day and its definitely a good thing for all of us knowing the higher the adoption rate, the bigger its value will become.
