I am surprised you can Australian dollars into Bittrex.
(do you have to convert to The US dollars, and then to a The US bank, and then to Bittrex?)
i mean, people in Hawaii can't even get their money into Bittrex, and they are a united state.
And, as long as you don't leave your HIVE on the exchange, there really shouldn't be too much problem.
I wasn't starting from AUD. Just rebalancing holdings of other Crypto.
When starting from AUD I go into BTC at btcmarkets.net and then off to an exchange that trades BTC into the alt-coin that I want.
