I'm not sure what your point is. You keep goalpost shifting. Bitcoin clearly is unfit as a currency as it stands. If you're will to argue that an asset with a 3% daily vlt is viable as a currencty, I don't think we will be able to find common ground.

There's no such thing as viable currency. For me it works fine. I'd rather choose higher volatility with long term value appreciation, rather than lower volatility with long term value depreciation.

Of course there is, for example it would be necessary for it to be useful as a medium of exchange. Which, bitcoin certainly isn't.

I can't purchase, for example, >50% of the basket of goods that comprise the CPI with bitcoin.

Sure, you can argue that anything which can facilitate more than 0 exchanges with more than 0 counterparties is, at least ephemerally, a currency. But if you're arguing that, you've already lost.
