My tax accountant said that if it doesn't move, it isn't taxed. It's only taxed when you cash out or buy something with crypto. But Steemit could be considered income on every click because you're earning Steem. That means you have to figure out what each click is worth in USD and subject to income tax.
Obviously the tax rules will have to be changed here because compliance is impossible. In a few years time when streaming money arrives, governments will be in a world of hurt...
That is true with any security which the IRS ruled crypto is...you only owe when you cash out.
That is going to be a tough one for the IRS to state since they failed to define cryptocurrency money in their 2014 (it might have been 2013) ruling on Bitcoin. They blatantly avoided the topic of currency (most likely on purpose since it only would have spurred greater debate) instead opting to tax as a security. Financial instruments given as compensation, like options, tend to be taxed when exercised (under a year earned income, over capital gains).
I am not sure what you mean by streaming money but the governments are going to be in a world of hurt because of blockchain anyway.
