What can one do provide a ATM bitcoin for its city

[Jaycee99]

The subject itself, what can one do or should know to provide a ATM bitcoin for my hometown.

While this question strike my mind other questions gather into as well

As I invest or buy a bitcoin ATM, what can I get in return? Will I get a money back that is more?

Just like when gethings yourself into trading that if you bought a token by playing with it, you can double your money?  And like buying a candy in a amount of 4 USD and selling in a price of 6 USD

Sorry if I have to much explanation I don't know if you understand my questions so I gother examples of what I am talking about.
