We can see that crypto is currently developing and many countries in the world are already using crypto as a means of payment, of course with advances in technological development all countries must accept crypto as the main payment maybe 9-19 years from now we can see crypto ATMs where -where.
no not all are going to use crypto . you can call it advanced but people are going to choose the old way of payment and that is by using fiat only . there is a unique and satisfaction feeling when you use a fiat compare to modern technologies which can only be feel by some persons . crypto atm's that your saying were also spreading till this date but alot of them are being ignored yet . it takes time for people to understand and gain trust in crypto
