Crypto is so spread now and I am sure that it will be used everywhere in the future at all. It is so convincing and reliable way of payment that it will be recognized I am sure. It has so much potential to change our economics in the better way or even replace them.
And it's so transparent, reliable, and fast. I love blockchain and how secure it can be, if technology improves further. It has so much potential. I am not sure it is able to "replace our economics" but it can improve it.
