I think there will be a lot of complication to continues after this, ever the introduction of bitcoin ATM and the way they have been seen as unpleasant offer to many, because they are less secured when it comes to privacy, they are being charges high for use as their transaction fee is high compared to other medium, lastly this is a third part developed devises, which i think are not safe to an extent for us all to use because companies are found being in charged and that is part of the reason to high fees and the likes, bitcoin is a digital currency and allowing for a physical devise like this may give room for more centralized involvement and this could be unhealthy to an extent to some of its users.
