That's why it's not only happening in South Africa but as well as other countries that they have to cut their ties but they have a solution for it as they make their website more accessible following the tight regulation of a country for their users there.
If I'm binance, I wouldn't hesitate to stop operating in a country that are too hard to cooperate, I mean regulation is a good thing for both the exchange, it customers and the country but when the country decides to feast on the exchange because they believe its generating revenue for them, that's a parasitic relationship instead been a symbiosis relationship.
I would have said they should create a decentralized exchange for everyone but that would give them another nightmare and focus demanding.
That's what they're thinking if they don't care to the crypto users on that country that's hard to cooperate with their business. But they do care that much since they're expanding globally.
And every country that they can cooperate is very important to them and hard to let go.
