sometimes I think if you look at the amount of token supply in such a large amount that trillions and trillions after the project runs several months or years, the token will be burned, what for if you make tokens with a large supply, but will be burned, ...?

yes it is a way to make the price of the token stable if the total supply of the project token is too large it will affect the price while the investor only has maybe around 10-20% of the total supply and that is a great way
