what do you mean "internationally"?
Is one other recognizing country enough?

Yes, and it's name will be California

@Conflux Unless I'm missing something, the Bougainville market should be trading below this one.

Is there a minimum threshold for how many countries must recognize it?

@JimHays I'd say at least 5-10 UN countries or if one of the five countries on the permanent council recognize them (United States, France, United Kingdom, China, Russia). But in all honesty there is probably a better way to decide what counts.

@Wobbles Russia recognizes a lot of non-countries e.g. Abkhazia.

@xyz hmm that's true
