October 6, 2017 had 92 ATM machines in my city.... today, November 8th, 2017, we have 109.
20% increase in the past month, in June there was around 64 BTC ATM machines. Crazy.
Which city are you referring to? And how do you know the exact number? Is there a listing where we can check all the bitcoin ATMs in a certain area?
And getting back to your topic: Yes, its a good business. ATM machines charge heavy fees, and if there is area where people use it regularly, it can be a good business to invest in.
The machines aren't that expensive either, but I think one would have to tackle the local laws and taxes etc.
