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, ...?

You are talking about unsold tokens get burned? It is actually good if that token is going to be listed on exchanges because it will help to reduce the total supply and better price value based on ratio of demand and total supply.
