So does cash, gift cards etc. Should we ban everything? You can use regular banking for big operations as well. Should we ban that too then? But then nothing is left :)
Try going out and buying, then sending $22 million dollars worth of gift cards.
Crypto clearly makes the whole process far quicker and more anonymous.
Surely we can all agree that the benefit that cash bring still outweigh the wrongful use. When it's no longer the case I imagine it will be phased out too.
