Not all governments have the same outlook on a cash-less society, so it will not be that easy. The only way they will turn this into a reality,
is if they can offer cheaper cash {no minting & printing of fiat currencies}, with full control to manipulate the cap... like they are doing
now. Many of the 3rd world countries do not have the infrastructure or the money to built it, to be ready for a cash-less society and the
citizens are too poor to afford mobile phones. { They will have to subsidize digital devices like the Treazor for people like this }
Yes that fact remains the same until today. Third world countries are countries with high average of poor people and that is to say that many who lived in the outskirts doesnt know what is a computer is and how much more cryptocurrency. But bitcoin is still felt though not by the masses but by the few individuals who have access to internet and have knowledge of cryptocurrency.
the issues with 3rd world countries access to bitcoin is not technology. africa and cuba both use phones.. take african countries use of Mpesa for example.
but right now its bitcoins own "spam" transaction prejudice holding it back (the microtransaction debate)
for instance in:
Cuba minimum wage is $0.05 and a loaf of bread is $0.015
california minimum wage is $10 and a loaf of bread is $2
buying bread in cali' is just about acceptable as not being spam and costs a cali' citizen 3% of product (~$0.06tx fee) or 25
seconds of minimum wage labour
buying bread in cuba is not acceptable as its deemed spam and costs a cuban citizen 400% of product (~$0.06tx fee) or hour 1hour 2
minutes of minimum wage labour.
moving an hours labour:
in cali' thats 0.6% fee($0.06c) to move $10
in cuba thats 120% fee($0.06c) to move $0.05c
