Is it possible and safe to buy ETH directly via a ZAR credit card or paypal? Final destination being a JAXX wallet. I've done it via EFT into Luno and then via Changelly into Jaxx(ETH). And also Luno to Jaxx(BTC) and then in-app shapeshifting. But I always end up loosing a sizable portion to the transferring and exchanging costs.
