I think if more people acknowledge and using bitcoin it will pop up more ATM
for now people still adapting the usage of bitcoin and
if more people request it I think the company or third party will place more bitcoin ATM machine
Yes you are right here. And I will add, if one country's government will truly regulates bitcoin as a whole, expect more Bitcoin ATM will be built eveywhere especially in the urban areas.
Base on my personal experience, it's a lot easier to buy bitcoins in person from someone than to use an ATM machines an go through the long process before having your bitcoin so I assume there's a lot lesser demand for bitcoin ATM machines than you might thought and that's the main reason that lesser investors invest their money's into buying and establishing an ATM machine in bitcoins.
Hmm quite disagree. Trading from person is risky except if you are doing your transaction by meetups.
