bitcoin is a future digital currency, i strongly believes that before BTC celebrate 50 years in existence at least one or two African countries is going to legalis it. because block chain network is expanding every day by day. and most of the countries in Africa have the knowledge BTC how it works.
The number of these countries may be higher. After a while, Bitcoin will be accepted by everyone, and if a few powerful countries accept Bitcoin legally, its acceptance in other countries will accelerate further. Some countries may be expecting such a step from a country that is stronger than them. I think these expectations will come true.
It's still early for many things and we still need to move forward. If we make this progress successfully, many good things can happen for Bitcoin.
