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.

We can't make a conclusion based on bitcoin atm growth. For now bitcoin market is dominated by chinese people and there is no bitcoin atm there. But there are so many minners. There are many bitcoin users in Indonesia, indonesia is developing country but indonesian could give contribution for Bitcoin adoption which will lead to improvement on bitcoin investment too. I think it isn't only indonesia but other small and poor countries can do the same thing, please don't underestimate people just because they are living in the poor or small country. It isn't always about purchasing power.
