Its impossible to have one or two coins in crypto space because one or two coins can't solve all the problems we have in this world in every aspect of technology or others, if you want to keep a coin for a long time make sure the coin or token solves one or two problems in crypto space or the world, this type of coins don't die easily because they have real use cases, its simple as that
That is well said. The best way for a coin to survive and in fact grow is to have a product that is based on a particular demand from the public. If a project is creating a product based on their own and does not even reflect the need of the public, however good the product is it will not succeed. Real use cases will make the product in demand and the coin as well.
