The existence of ATMs in several countries is only to overcome the problem of difficulties in transactions because when making a transaction not everyone receives payment in the form of bitcoin so that this ATM is very necessary to convert bitcoin into money.
https://coinatmradar.com/It isn't that deep of a search before you manage to find a single site that would provide you knowledge into where these ATMs stands are laying out. I think this should be at least the maximum that Bitcoin should be in terms of interaction with currency notes, since it is a decentralized entity in the economy. There were even some suggesting Bitcoin Bank, and they have no idea what they're talking about.
