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.

People from these countries are more reluctant to risks. They are able to buy some crypto and do not jeopardize their everyday life. It is a cost that they can stand and also I should not forget to mention that developed economies have more options to purchase cryptos. This is because they are markets for many institutions.
