Today you can find so many cryptocurrencies and Aurora is one of them. Aurora is an arising currency in Iceland.
Auroracoin (AUR) develops a free monetary system parallel to FIAT coin. It is not controlled by a central system, it is independent. AUR works with DigiByte infrastructure and it is well-known in cryptocurrency market. AUR has big security systems and they reduces risks to minimal.
Despite having an infrastructure that so valuable AUR is not being used by any people because it is only for Icelandic region. They get bigger and bigger day by day but this limitation is a very bad side for them. I think they should become an international project so everybody may use it because I adored their security mechanism.
