I'm also from South Africa and contrary to what people believe - our exchange controls are far from "archaic" - trust me to know..I live here. Sure there is tight regulation comparatively speaking but there are loopholes that can be exploited. The only truly restrictive condition is that of the taxes paid on incoming and outgoing payments which is slightly more exorbitant than is the norm internationally - that is if using SWIFT. Of course we have our "ways" to get around this
One the positive side - people are starting to get into crypto and I see trade volumes increasing on ICE3x and Luno (both local exchanges). The biggest potential though exists on LBC - there are people who have thousands of completed trades just by selling BTC in cash at between +10 to +30% !!! That is an insane profit margin !!!
If anyone is interested in bulk arbitrage hit me up - but please be serious and legit, escrow is a must.
One last thing: Brazil, Russia, India, China, South Africa have formed the BRICS agreement/treaty/?. Learn about it - and what it means to do bilateral trade/business under this sphere
