Which Currency to use?

Hi all

Being a newbie in Australia and currently having my trading account in USD my question is this.
What is the best currency to have my account in?Considering that Britain and the US continue to buy their own debt and create more money.
I know the USD will get weaker to the AUD so is my best bet the EURO?
I ask all the experienced currency traders for their view:)

Generally speaking, the easiest thing to do is keep the account in your own home currency. If that’s not an option then the next best option is probably to have it be in the currency you are likely to trade the most.
