In the future value will depend on various factors such as market demand, technological developments, regulatory changes, and adoption by users and developers.
That's right, I agree with what you mentioned, some coins in the future and even now they still depend on technological developments and market demand on exchanges. So far these are the only two important components to create a product that has good value and is useful for many people.
Exactly, without a product that is useful for the people, it will mean that the product has no demand, which means it is difficult to get a selling price, where this exchange rate shows the quality of the product being sold. Like Bitcoin, which can have an expensive price because Bitcoin is used by many people and has very high demand.
