That's interesting too! I think I read something about another company bringing this technology to the stock market. I'm going to say Iconomi but I think that's more from a portfolio / fund management perspective though. Nevertheless super interesting concept. But back to ATO, you can clearly see the 'double interest' there as well, right? Whatever ATO can do ensure that gains are properly taxed is in their interests as well. It's one of the reasons I only started trading cryptos after the EOFY in the hopes that they will have some clearer guidelines come next EOFY on July 2018. Just thinking out loud, say you have a portfolio of all sorts of coins, which rate would you use to declare back in AUD? The average on an exchange? Hmmm, haven't really thought about this much yet. Anyways, thanks for your reply @crypto-ta!
