my understanding of how atm's and how they work is that the "provider" (you) would charge a fee in order for someone to use this service that you are providing.

the next thing is to make sure that you are able to afford to run an atm. do you have enough funds? can you re-establish an operating balance in order to afford the transactions that would take place?

the last thing that i would like to say, is location, location, location. if you think that this is the best spot to support canadian bitcoin users then by all means go ahead.

i think that this is a cool idea and that it would help a lot of people to get cash in a safer and faster way. although i am unaware of most of the practices of how a BTC atm would work. i hope that i have been able to provide productive feedback

thank you for your time, and i hope that you have a good one!
