I'm sorry, I'm a bit confused about the process of transferring AUD to Coinbase. I've read that it's possible to buy cryptocurrencies like Bitcoin on this platform using AUD, but I'm not sure how the actual transfer works. Do I need to convert my AUD to another currency first? Or can I directly deposit AUD into my Coinbase account? If so, what's the process for doing that? I'd appreciate it if you could provide a step-by-step guide or any relevant information that could help me understand this better. Thank you!
