I can confirm that the Bitcoin ATMs I have seen are all from the General Bytes unidirectional ATMs for buying Bitcoin, not for selling as you seem to require. There is this documentary in Dutch that showed both so maybe you can glean the location for bidirectional ATMs, called BAMThree.
https://t.co/lIxqMZ7bsd?amp=1Germany's BaFin has approved all banks to allow Bitcoin to Euro ATMs so maybe your country will soon have them?
Wait, ATM's are to withdraw our money, for payments and buying something, we already have bill payment machines. Well, at least in my country we can buy bitcoin with some bill payment machines, not from ATM's.

Banks can set higher fees on bitcoin transaction withdraws and still have people because a little bit monopoly, there is a potential of good profit but in a good manner. You have to let people withdraw anonimously if you are looking for stable profit, otherwise your ATMs will be for some fanatic people. Why? Because serious people prefer to exchange with very low fees and have money on their cards.
