I don't know if perhaps i'm overthinking this, but considering the evolution of money from the beginning of time where different things have served as a medium of exchange and now currently banknotes.
In fact, you are way underthinking it.
On same trend, we are slowly witnessing the evolution of money to crypto and i can't help but wonder if crypto is the final stage or there may perhaps be another revolutionary idea to replace crypto as money after crypto has been accepted.
What do you think?
Crypto is not "money". "Money" is not crypto. "Money" is not "a medium of exchange" and "money" itself basically did not evolve since it has been established.
Nevertheless, up to this day, many economicians still do not recognize the findings of ethnologists made around 100 years ago and still think about "money" as a thing instead of acknowledging that it lies in the legal sphere.
In order to create a "money"-equivalent crypto at all, it needs - as with "money" - creditors and debtors, which clearly runs counter to the premise of decentralized verification and anonymity, since it involves contractual modalities with mutually liable parties who must of course know each other in order to ultimately be able to legally enforce their contractual claims, which only these two parties mutually negotiate and determine and not tens of millions of anonymized users who are legally intangible.
