We can not deny the big country with good economy, it will make the society economy better too.
So they can follow the economic development and participate in transactions and investments in Bitcoin era.
How the people of small countries can participate in participation and benefit from it?
It would be very difficult to calculate the statistics of users of each country, but the comparison of Bitcoin ATM growth from this early 2017 report can be the initial reference of the statistics.
Perhaps by the end of this year, there will be more Bitcoin ATM growth across the board due to the growing interest in bitcoin this year.

With these country who has better economy were the one involved with bitcoin. One thing I know because they were see something that makes their economy more progressive that's why they embrace it they let their people to invest with bitcoin unlike any other country they don't like it because they can't control bitcoin that's why different country banned it.
