Hello, im new thanks for having me. I reside and am an Australian citizen.
Edit: Privacy and other aspect of cryptocurrency doesn't go together you have to choose whether to go for privacy or Easy to carry out wallets.
Privacy may not be easy (fast as possible to carry out) but it's secured but easy to carry out wallets may not be secured as privacy oriented wallets
Welcome! Please note that what Churchilvv says above is correct. Privacy is difficult to gain and easy to lose.
Also which wallet would be the best for this purpose? Especially ease-of carrying out the procedure?
Privacy can't be accomplished without running your own node. Nevertheless, it is good for bitcoin that many new nodes join the network. So it's a win-win case. I suggest you run your own version of
Bitcoin Core. It requires 1TB SSD. You can run it on an old laptop or an old computer. Personally I run it on a raspberry Pi. Once you have done that, then you can
connect Sparrow Wallet to Bitcoin Core.
Then you are much more private.
As mentioned by Churchillvv, Electrum is great but it requires one more step to connect to your own node, so I definetely suggest it, but it requires a little more effort with which I won't bother you right now.
If all of the above sound difficult, then you can just download Electrum and play... But there will be no true privacy!
Which exchange should I choose and what are the best for anonymity/security and ease-of-use to buy BTC and then make a small purchase on an EU or US or other site which requests BTC-only as a payment method?
The exchanges are basically split into 2 categories:
1. KYC exchanges -> You must give a lot of personal information to use them. Actually too much personal information. In this category the most well-know ones are: Kraken, Binance, Coinbase etc.
2. Non-KYC exchanges -> Nothing is required to use them.
There aren’t any posts on AUD or Australia on this forum.
There must be Australian members on the forum though! To be honest it doesn't really matter where you are from. The tools that we need are available everywhere!
