Crypto definitely represents the next level of evolution of money, but it's also definitely not the last. As much as we love crypto, it's still too imperfect to be considered the end product of economic evolution.
If we do really tend to look closely and have some in depth analysis then you could really say that this isnt the last or end product which same as you said.
Its better not to be that hopeful nor being too optimistic on how far crypto could go because no matter what fiat would really be still the best of things
but at least we do really have some options for us to take aside from fiat which is something that we do really appreciate on.
