Are there any correlation studies showing the number of (non mining) full nodes per country (total or per/capita) compared to average internet connection speeds?
I know there are great differences between connection speeds depending on ISP and if the users are in rural or urban areas.
The time to download an entire blockchain from scratch for maximum security can take a very long time in some places. I want to know how much this discourages people from using full nodes (in favor or SPV wallets).
Comparing average connection speed to number of full nodes (per capita) in each country is what I am looking for.
