And if they'd bought dollars they'd be even better off. How wonderful.
that's easy to say, what do you think the practical reality was? (remember reality, from whence you were attempting to pitch your pithy retort?)
I suspect that dollars have been in shorter supply compared to Bitcoin, as highly indentifiable pieces of paper such as 100 dollar bills probably don't make it across the Argentine borders in the same quantity that the smugglers always hoped.
this in fact only demonstrates an advantage of Bitcoin over paper cash under hyperinflation conditions: if you still have internet, Bitcoin is in greater supply. It might be 2nd choice, but that makes little difference if the various trolls under bridges "confiscate" the 1st choice (which in addition pushes up the dollar exchange rate anyway, making it less attractive even if you can get your hands on some)
