This morning I listen to the Swedish radio and heard the news about a E-Krona we in Sweden could get within let say 5 years and http://www.riksbank.se/en/Press-and-published/Speeches/2016/Skingsley-Should-the-Riksbank-issue-e-krona/ is more information about it.
If that happens Sweden are gonna to be the first country in the world to get a national digital currency in a couple of years, but first the Swedish Riksbank need to perform an investigation under 2 years.
