I think they are great at promoting bitcoin, if people start seeing bitcoin atm's everywhere it will be great for the brand. Although i do think that they are abit pricey but sometimes if you are only buying a small amout then its fine, and its good to support those who accept bitcoin.
I worried that people will think that bitcoin is some short of bank or anything related into it if the bitcoin ATM were placed near to local's bank ATM
some people will try to search in the internet what is bitcoin but the rest is not,they will just let their opinion,if there's some short explanation in the ATM that'd be great to entertain people
