The USA is basically accepting Bitcoins and the like as legitimate currency, with the recent FINCEN guidance and with the various positive results in the courts. I would be more worried about the EU banning BTC than the USA, because of all the issues the Eurozone is having financially, as part of a general effort to prop up the Euro currency and the many failed Eurozone banks.
