Countries with good economies usually have developed financial industries. There are many investors in the developed financial sector. The investment community has been popular for decades. From the stock market to real estate, there are a large number of investors entering, so the developed countries are more likely to accept bitcoin.
I agree with you and a country with a good economy will provide a smooth internet network, because the main thing about crypto is the smoothness of the internet signal and the internet that is smoothly and cheap can provide all information, such as cryptocurrency.
