It is not possible to answer this question in exact numbers, however, if you think about it, it becomes clear that it will be very expensive. That is, the price of one bitcoin will be very high - since there will be a frantic demand for bitcoin - after all, it is legal tender everywhere and everyone needs it. Such demand and the absence (suppose) of supply that could satisfy such demand - there is a shortage and prices rise. I think it's too early to talk about it, but it's always good to dream!
