From what i can see Coinbase offer the cheapest AUD buy price. Is that correct or does anyone know of a cheaper place to buy BTC with AUD? Also what's the buy process with Coinbase? do you buy with credit card? do you have to store your credit card details on the their site?
yes to all questions, and you will probably have a $150 dollar buy limit to start with. just need to id verify and verify your card and your good to go. two things to be aware of, they charge you a card fee on top of their rate, and your card most likely will charge you an international transaction fee (even though your being billed in aud)
