Sounds great.
But how we can redeem it...has btc came in cash as notes. Or its a digital only.
What do you mean redeem it?
You put your euros in and you get your BTC out, and the opposite. Pretty straight forward, but without privacy anyone with access to the machine will know how much money did you run troughs that because again I doubt it's anonymous and no one here is saying exactly what do you need to provide to use the machine.
