Every country can be a good place for cryptocurrency. But I think it will become better if it will establish in the country that is industrialized already. Africa is good also because a lot of natural resources can be found in this continent. There are many things to be developed and of course, they can make it specially, nowadays that there is a globalization.
Africa is a big continent and bitcoin can have a great potential there. If only Africa can adopt it fully, it will mean a lot of support and strength for bitcoin.
Indeed it is not only America but there are a lot of other countries who are using bitcoin and the people are investing in it, actually it makes the country economy well developed and in some other words it gives best opportunity to earn money even without investing anything, it is being use as job in many countries, so for me it is time when bitcoin will be legal all over the world.
