Good news, the Bitcoin ATM's are realy easy to use although the one I saw was limited to just bank notes and not credit cards, very easy to use it actually surprised me.
As Greece make bitcoin as legal and install ATM which is easy to use.Very soon bitcoin will succeed through out the world.Huge potential area for bitcoin is at "International Airport"and "Shopping Mall" .It wil make bitcoins more in demand http://www.coinfox.info/news/2256-greek-bitcoin-enthusiasts-installed-first-bitcoin-atm-in-athens
Best potential for bitcoin would be if it would be available to use it on normal ATM's, upgraded to support bitcoin as payment.
There would be no more need for new ATM's, and finding locations, user would just go to any "upgraded" version of ATM and make his transaction. I'm hoping that we will see this as an option in near future,
but to achieve it, bitcoin has to reach much wider audience than it has today, to force the ones fighting it to give up and join . Is this only a dream; probably, but it's also one of the possibilities, like 250$ once was.
