Why should the US government fear bitcoin?? - bitcoin isn't usable as a transactional currency. it costs $30-40 per transaction. Plus other currencies are gaining steam, and offering other choices for people to transact - bitcoin isn't rare to be a store of value.....everyday there's a new viable cryptocurrency springing up - bitcoin isn't safer than dollar.....it can drop 90% in any day; no official entity is going to prop it up and make sure it doesn't crash. it can be banned by countries (and has been by a few) - bitcoin isn't easy than square cash or wires.....it can take several weeks to send money. plus the transaction fees are high
