I don't particularly think Hive is a standard blockchain or can be assessed in the same manner. In Australia Hive is even simpler and can fall under hobby.

You write a blog, you get paid. Doesn't matter what currency or object the pay is in, you're getting money. Thus it comes under income and is reported under income tax.

This also applies to any work you do where the payment involves cryptocurrency. Staking on a network is income. However, if you hold you need to pay income tax and then capital gains tax ontop of profits once you sell.
