Not every platform through which you can buy and sell Bitcoin with the South African Rand will trade at the same exchange rate. Therefore, the prices you see on Luno are unique because the supply and demand — set by buyers and sellers — is also unique and will differ to what you’ll find on other exchanges or on Google.
Can I use Bitcoin on Amazon?
Even though Amazon does not accept bitcoin, it does accept gift cards. The Amazon digital gift cards act just like U.S. dollars and can be applied to all product purchases, and some gift card hubs, such as eGifter.com, Gyft Inc. and RewardsPay Inc., let you pay for their digital cards with bitcoin.
