Just like anything else, it's worth what people are willing to pay for it vs what people are willing to buy it for.
Currently bitcoin is just a digital commodity with a finite supply which makes it a good store of value if people continue to use it.
The thing is, there's nothing preventing bitcoin from tanking and becoming essentially worthless besides people buying it because the price is low.
If in a hypothetical future the bitcoin price becomes stable then it will become a valuable commodity. It's value is wholly derived from it's users and nothing else.
It's not very convinent for governments or large institutions to hold it in it's current form since it's too easy to steal without leaving a trace. For government use there is going to be needed some development to allow for government or Central banks to have complete control over the currency without giving that control away which I think might be possible. In that case settling international transactions in bitcoin as opposed to the dollar for BRICS countries might be an option which doesn't use the US dollar.
All the other uses IMO are pretty much fluff such as paying in bitcoin.
Nazis is a strong word for people trying to maintain order in the galaxy in the face of rising terrorist activities.
