This is indeed a delightful piece of good news. Hopefully, there are no cameras on these Bitcoin ATMs. This can well protect everyone's privacy.
El Salvador has played a good lead. It is believed that many countries will follow the example of El Salvador and launch Bitcoin ATMs one after another.
Each ATM have camera and this has been installed by the company for protection of their clients so expect that they will also put that on bitcoin ATM machine for the same reason and we should not get afraid of it as bitcoin is already a legal tender in their country so for sure any transaction related to bitcoin is protected by their local law. You only get worried about those things if you do money laundering since for sure you will be seen and sued by the government or any legal authorities if you used this machines for withdrawal.
