If we arise the idea of paying everything via electronic devices, we must also take into account "Least Developed" and fourth world countries where modern technologies aren't developed properly.
Initially Bitcoin only growing rapidly in developed countries, but now there is everywhere, this progress is running normally.
"Onelife, onecoin" very successful in Africa, though wrapped in HYIP. In a third country/fourth, all understanding bitcoin begins with gathering business/member get member, and doesn't require online (only a few people who should be online), and as a result almost all of them can buy supplies pc/internet on their own. So all will automatically fill, we shouldn't be confused, They are in third country/fourth that will find answers themselves.
