Of course, today, cryptocurrency is very actively involved in a person's daily life, but nevertheless, to a greater extent, people use cryptocurrency as a source of income, and not as a means of payment. In any case, we need bank cards for payments and for cashing out cryptocurrency. I would not mind being able to create a virtual bank card of an international standard, so that it has nothing to do with my state and the tax office would not ask me questions about every $ 200 in my account.
