There are so much 7/11 stores that very accessible and friendly users and also you can purchase small amount with less hassles
And what I believe is it’s not the machine or the volume of those is important to help cryptocurrency progress but it’s the volume of peoplec accumulating crypto’s and we cannot count this from the machines installed but from the buyers itself
