It depends on how you treat it. But now that the world is slowly embracing Bitcoin as a form of currency, it's starting to look more like a currency, and I believe that's the idea, as far as the whitepaper is concerned. Treating it as both will hurt, though, so no issue there. Just hold on to your coins if you treat them as an asset because if there's one thing with high certainty in the crypto world, it's that Bitcoin's value will keep increasing as more countries open their doors for crypto.
