Congress' new report tells you where Bitcoin is legal  Bitcoin
on top of paper currency  Unfortunately, you can't assume that
Bitcoin is legal everywhere you go -- it's safe to use the
digital cash in some countries, but it's mostly verboten in
others. However, you won't have to travel blind. The US' Law
Library of Congress has just published a report (PDF) that
outlines Bitcoin's legal status in 40 countries. In short, the
currency mostly exists in a gray area. While countries like
Germany and Finland have cleared Bitcoin for legal use in some
conditions, most nations either haven't regulated it or see it
as too risky. Don't leave your physical wallet at home on your
next vacation, then.
