Bitstamp is a European bitcoin based in Slovenia exchange that has been running continuously since 2011. Its reputation has also made it one of the most common places to buy bitcoins on the internet. They accept U.S. Dollars and European Euros. Bitstamp keeps things pretty basic. It offers two-factor authentication that tethers a user’s account to a phone or other device, as well as a password, to protect your account from hijacking. Bitstamp also commits to preventing money laundering and other shady financial practices on its network. As with most bitcoin exchanges, Bitstamp doesn’t let anyone buy bitcoins with their PayPal balance, to prevent scammers from reversing PayPal transactions to collect bitcoins for free.
