Why are cell phone nicknames so expensive? Why do so many people still want to buy it? Please discuss it and answer quickly! thank you

Let me talk about it first! In short, don't laugh at me! Handset nicknames are easy to remember, and there are some lucky numbers, such as if and mantissa 8888 6666, so the price will be higher! Some people regard this as a symbol of the rich, because the poor will not pay a high price for such a number, saying that they don't have enough money to buy such a number! Therefore, nicknames are expensive! I'll buy it if I need it thank you
