That is the logical conclusion of the institutions, since they are basically crypto banks. However the underlying coins are very different from the underlying asset in a bank, even if their use cases haven't come to fruition and the most common use case is speculation. The use cases that currently exist and are important, though probably not to users in this forum, are borderless transference and the ability to truly own your assets without a governing body or third party institution able to touch them. A significant portion of the world either: lacks institutional banking or is under an authoritarian / corrupt government that could seize their assets just because. Which means the current use cases are incredibly valuable to those individuals. For most users here coins are probably a novelty used for speculation or asset diversification.
