If the question - which crypto is the most owned - easy (it's BTC), is the question of crypto users per country more difficult.
It is impossible to predict which country has the highest number of crypto users.
However, some of the countries with high adoption of cryptocurrency are Japan, South Korea, The United States, Germany, China, and Canada.
