There used to be some Australian companies (probably just owned and operated by one person, mind you) who would take your BTC and pay you via BPAY, which for those unfamiliar it is electronic funds transfer usually for payment of bills for services like electricity, gas, insurance etc.
In all honesty it was good because:
- You could confirm their payment by contacting your service provider (bill issuer) or on their website
- I don't think they could do anything malicious with only the bill/payment reference number that you had to provide so that they could send the funds
- It was a 100% tax dodge
