Actually I am not well informed about "Monacoin". Anybody please inform me. Thanks.
This is the only Japanese altcoin. Japan is the only country giving digital currencies a legal status as JPY
Sorry but not the only one. There is also Fuji with a strong dev. True is Mona is moving faster and it has a bigger community but is not the only one.
That is Koreans made.
There is no Japanese community in fujicoin.
