Actually, it is an issue that has been around for quite some time, and they have been an area of entrepreneurship that was launched by nature of the traditional currency (fiat) that we handle, so how not to use a bitcoin ATM to link the currency digital with the real world.
This topic reminded me of a pic where Gavin Andresen appears who is shown in a group that is developing this type of business.

On the subject of using them I think that as soon as I have the opportunity I will take a photo with any bitcoin ATM, in fact I think that one should check if there is an ATM in your area or when you travel, whether you use it or not it is a matter of "priorities".
