So... this was a tax raid? Quite a harsh response, considering the rules were drafted 12months ago... What are the money laundering measures that caused Aussie banks to disown Bitcoin? Maybe that could shed light on the motivations behind the raid?
You're making very ambitious assumptions that the tax raid is related to the rules that were drafted 12 months ago.
I'd bet significant sums of money that he isn't in trouble for creating bitcoin. Its more likely to be some other action he has done, possibly with bitcoin.
