 						<p>Bitcoin is a type of digital currency in which encryption techniques are used to regulate the generation of units of currency and verify the transfer of funds, operating independently of a central bank. See <a href="http://www.weusecoins.com/" target="_blank">weusecoins.com</a> for more information.</p>
