Withdrawal into Rands is a flat R8... where are you pulling 7.5% from? And if you're referring to BTC transfers, best you learn about the miner fees attached to it before you blame Luno
Nope not ZAR withdrawal, but yes, I did forget about the miner fees. It's still the case that you're taking a steamy dump to the chest by buying locally and moving the coin to an exchange with more variety so that you can deal in other coins.
