well what I ask is whether its influence on the economy
It doesnt effect the economy but it effect the people who uses bitcoin, people who are in bitcoin are into trading they gain wealth only for themselves and the profit that they get doesnt affect the economy of such country.
Yes, it only affects the users of bitcoin and when the users are doing well, then apparently their lives will be affected and may also pave ways for some other ideas they have which may help solve some little employment issue.
Still, when we are talking about the economy at large, then we have to also realize that not everyone would accept the usage of bitcoin and some will be limited to it. So, depending on the population of bitcoin users in each country, there may really not be much difference.
