I am about to tear my hair out, its such a convoluted process, but slowly making headway.
I got the Bittrex account opened, no problem there, just need to understand the process.
I tried https://anycoindirect.eu/en/buy/bitcoins to purchase Bitcoin, but they do not verify Australian mobile numbers!
So next step was to look for an Aussie trading platform, came across this one https://btradeaustralia.com/ the verification process is a little slow, and they charge almost 5% in commission.
A bit of trial and error, but I am determined to make my first purchase of Bitcoin.
I will update this post with a complete idiots guide to making your first Bitcoin purchase and transferring it to Steem, as soon as I have success, wish me luck!
