With the standard "I Am Not A Lawyer" disclaimer, my read is that miners might be ok if
- They sell bitcoins for fiat, via a licensed exchange
- They purchase goods and services entirely within the bitcoin economy
The first is obvious. The US government is certainly within their rights to regulate the US Dollar, and ditto for other government fiat currencies.
The second is vastly positive. Stimulative for the bitcoin economy, encouraging a broad market of services priced in bitcoins.
And the third, more general point is implied: bitcoins are legal for regular users to possess and spend.
It is true that bitcoins were never illegal, but having a big government issuing an affirmative statement "bitcoins are legal" (in effect) is great news.
Agree. I read through the statement, interpret it this way, and see it as positive for BitCoin. The ground is clear and we know where we stand. I don't understand the pessimism about this. It looks like a very pragmatic and commonsense position they are taking.
