It's not a currency, that's a misnomer to a great degree.

Which nations are supporting it as a currency? Essentially none. If something doesn't have the currency status backing of a single major economy, it plainly can't be considered a currency. It's a store of value.

Sure, we could be pretend about it (any medium of exchange), be idealistic, and say that you don't need nations to back something for it to be considered a currency, however that's repudiated by every possible aspect of how things actually work (and will continue to) both locally within an economy and internationally in trade.

Gold also is not a currency today, it's a store of value. I don't think anyone confuses gold for being a currency and there's no reason to confuse Bitcoin as being such.
