In some countries there are Bitcoin machines where you can exchanghe Cash and Bitcoin. Would you use this machine or rather buy your Bitcoins in the Internet?

Depends on how I need the money. In our country, we mostly use one exchanger to exchange Bitcoin into cash but that takes time sometimes, a day. So basically we wait, but if there are these kind of machines here in our country, I will gladly use that kind of exchanging my cash, atlest I can't wait.
