Either bitcoin will be worth a fortune in 10 years or it will be worth nothing. Either way, low risk/extremely high reward.
Bitcoin ATM's are only increasing worldwide..... that might be the easiest method for attracting new "clients"
Just a matter of time

At this point of time, most people predict the price of bitcoin to be.... $1024! That's why they are only willing to buy at this price at the moment.
As for Bitcoin ATMs, they are just for advertisement and awareness. They are not useful, let what others have mentioned, due to the high price. This is why many Bitcoin ATM disappear soon after installation.
