The question is whether bitcoin would be accepted as legal tender in 5years time and that time frame is too close for such .
Bitcoin need more awareness, education and the use of internet facilities are important as we know most rural communities of developing countries are struggling with education and the likes.
The acceptance is possible but not in 12years time.
This requires much more years. Bitcoin is not the first year there, and during this time, many have not even heard of it.
