Those are good videos, but I always prefer to talk about how most fiat currencies are really no different than many cryptocurrencies.

USD is not backed up by anything...other than the Us government...but what does that even mean? It is not backed by gold...that went away long ago.

Crypto is worth what people will pay for it. It is a store of value, like many other things. I try not to go to into depth, but it can get quite complex when you dive into the details. Very interesting stuff, at least to me.
