Good for them. This is exactly the supposed use case of decentralized currency.

Now we just need a decentralized currency that is not ridiculously volatile and / or subject to the kind of absurd price increases that bitcoin has, and can be spent easily and without fees, and that isnt a scam. I'm still not convinced that anyone is even working on these requirements

Some guts on these guys.

Poking fun at the legitimacy of a national currency in the face of a judge paid in said currency.
