So you're saying that a crypto backed by "tech" (I have no idea what that even is) is pretty much as good as a fiat currency backed by an entire nation? Mkay.
Nope, never said that. In fact, I explicitly stated I don't think the success of crypto as a whole depends on it becoming a replacement for fiat currency.
I already explained why I don't think it ultimately matters if governments recognize crypto as legal tender. A crypto token just needs to have value within its given network/ecosystem. And all it needs to do that is be able to be exchanged for something useful/desirable within that network.Also you haven't yet explained how a crypto can work in a world where no government accepts it. i.e. how do you think craptocurrencies can possibly be allowed to exist alongside an actual government-backed currency within the current legal framework? What government would allow this to occur in a significant fashion?
For example, consider a video game that has in game currency which can be purchased with fiat currency. It doesn't matter if the government recognizes it, as long as it can be used to buy things which gamers care about, it will have real world value that can be measured in fiat.
A crypto asset could have similar value, but would hopefully have a much broader use case/user base than an in game currency. And that's what I mean by "tech". A blockchain solution that solves a real world problem and provides real world value to its users/customers. I gave an example of Sia cloud storage. Rather than relying on a single entity to store your data, which opens you to possible censorship and/or a single point of failure, you can use distributed solution in which you don't rely on any individual entity.
