The future of Bitcoin lies in global use.
When the big exchanges will not be only from USA and China, when every country will have at least in airports and shopping centers bitcoin ATMs, when you'll be able to buy with BTC from your fav shop in your city/country, when selling bitcoin for your local currency is not an issue / a tough task, then Bitcoin is a succes. Globally.
their is no need for Bitcoin ATM's
ur Smartphone has 1 million X the power of an ATM
No I also think this is not needed everyone has a phone these days or something else that is digital with them so that is something you can spend your bitcoins with.
I think a ATM is not necessarily at all because everyone can just use there digital money on their phone or their smart watch in the future.
