I am a complete noob when it comes to crypto and would like to buy some and use it for an anonymous transaction. But I don’t know how to though.
Can I buy it with my credit card? What are some good wallets or buying authority? Should I go for an international one or stay local?
The easiest and cheapest way is to sign up at a regular exchange and buy Bitcoin Cash (BCH)
https://bitcoincash.org/
If you want to buy with credit card take a look at https://trocador.app/
If you want strong privacy then you can try https://retoswap.com/ but it is more difficult and expensive.
Here is some BCH to get you started the right way. Download Selene wallet and just scan to claim https://selene.cash/
