Yeah some countries arround the world want to block cryptocurrency in thier respective countries and we don't know why they do that as we all know that cryptocurrency is one of the best investing platform, maybe those countries don't want their people engage in crypto cause they think that once it will happen then thier people will go for investment rather than working from then with a minimum wages. Just an opinion we really not know what's the main reason.
In most of the countries cryptocurrency is not accepted yet but those countries which show no restrictions towards cryptocurrency will not show any restrictions in my opinion because they realized that how worthy it is. No one can deny the importance of cryptocurrency and the financial system of most of the individuals become good with the help of crypto investment.
Actually some country also banned crypto because they know the fact that people move towards money making ways so they will move away from other jobs which is important for country's prosperity. There is a hope that eventually every country will accept bitcoin investment as there is job limitation in each country and providing job to every person is not feasible.
