Better invest in crypto. They at least requires some work. In a case of fiat, they can be drawen easely.
people nowadays prefer physical money because it is still existing. and its the most known money today.
but as electronic money enter in, few people are starting to get interested with it. why? because they dont need to touch money, or hold it but they will just scan something at that easy. people like everything to be easy and less hassle.
