I agree, bitcoin "will not replace the dollar" and it also won't wash your dishes.
But its best damn offshore online speculative investment the internet has ever seen.
That is kinda crazy statement in itself... But there is quite a lot truth in it...
And did you comply with FATCA then, which was one of Armstrong points of how they will put you in jail (if you are a US citizen).
Saving this as evidence that bitcoin investors do understand it is an offshore investment.
Saving the information here for the authorities to use in the future.
