Talking about tax strategies, I'm wondering if you buy bitcoin & altcoins in a SMSF which is in pension phase therefore all income & capital gains are tax free anyway, how would an auditor be able to audit all your trades as all SMSFs need annual auditing? You would be transferring coins all over your 10 different desktop wallets, mobile wallets and all the online exchanges. Would end up being impossible to provide all this data to the SMSF auditor.
