Nothing more than buy or sell. There is one bitcoin ATM in my country, check
https://www.youtube.com/watch?v=QFD9DQtiivs , and its located in bali. But looks like that ATM only have buy feature and don't have sell feature, i maybe wrong but usually in here, we sell bitcoin through exchanger.
ATMs in Ubud have been dismantled by the government, maybe only the remaining ones in Jakarta. that's the news I know.
can a bitcoin ATM be used to withdraw FIAT cash?
