Many countries I think adopt this kind of transaction like bitcoin in some atm's machine and buy some stuff with it. There are a lot of advantages with bitcoin in atm, first buying bitcoin in atm is much safer compare to some scam transactions.Next, we should used and be familiarized with the things we used so that we can surely trust with it. For me, there are some disadvantage with this but if we look at the positive way, disregard with the negative way.
