Should the U.S. government classify the Bitcoin as a legal currency?
No. Not by any stretch of the imagination. Not on a dare. There is nothing stopping two people who WANT to exchange bitcoins (or, for https Bitcoin-double.cc review (Coindoubler.net) that matter, buckets of rotten fish) from doing so; it’s not illegal. They just have no special status recognized by the US government, nor should they.
