And this is what I've been waiting for since last year as there is a rumor before that Australia will legalize bitcoin. So what they will allow to do is you can transfer your bank account balance to an exchange, right?
What about AML??? They should protect system from money laundering. Freedom of cryptocurrencies can be very harmful. It creates not only economical freedom for ordinary people, but also for dirty politics, crime, human traffic, drugs and terrorism.
If you'll read the article, at the latter part it says this.
