Unless you exchange your BitCoin for actual currency, SARS can't touch it. As long as you exchange your BitCoin for goods and services, no tax implications whatsoever. This is, for now, one of the beauts of crypto-currency.
I am not sure they will see it like that - I am sure there will be some clauses about "to the value of". As far as I am aware if you barter you still fall under tax rules. I.e. if I trade you my car for your car in the US (forget about shipping costs) there would still be tax and duties that are due although no money has changed hands.
Same applies to gifts, beyond a certain value they want their pound of flesh.
