that is a really great news for the whole crypto world. i am very curious which coin will be there, but i think and hope it will be bitcoin (or eth). do you have any links to confirm your news?
it is neither of those!
OP is trying to be vague about it for some reason. the real news is here:
www.businessinsider.com/sweden-cryptocurrency-e-krona-riksbank-2018-1and it is saying they are creating
their own cryptocurrency which is only based on bitcoin and the blockchain technology.
and contrary to what the article says Sweden is not at all the first country! they are at least the 5th one. there is already Venezuela with their own cryptocurrnecy called Petro, there is India with their own called Lakshmi,...
Yes you are correct, there are a lot of crypto back currency by a government. As far as I know that there even more before the Petro (Venezuela) and Crypto Rubble (Russia) but they all failed.
But I'm not surprised by the move of Sweden because first they are one of the friendlies crypto country you can find, second they have strong financial institutions and even experimenting on a cashless society. So it would make sense for them to get their own coins as alternative to cash.
