Can Bitcoins or other coins be transferred back to US dollars? Can Bitcoins be transferred back to US Dollars?
Bitcoin is just like anything else you can own.  You can buy it using any currency that a seller is willing to accept, and you can sell it for any currency you are willing to accept.  You aren't transferring, you are trading.  A bitcoin is always a bitcoin, and a dollar is always a dollar.  You simply need to exchange it with someone.
