From all of the anti-bitcoin arguments against it not being a proper currency that i've heard (and trust me i've read TONS) im yet to see a single one that justifies such claim. Every single claims end up being a critique of how it lacks intrinsic value or how it lacks a proper marketcap to be less volatile, both already refuted.
Ok. Let me ask why do we want it to be a currency? Maybe you are looking for credibility? But if all the arguments or critique have already been refuted in your opinion why is bitcoin still only used for gambling and speculative trading and not as a currency? What's stopping it if it's such a panacea?
This is clearly a warped view on reality. Bitcoins are used for far more than that. Normal uses. And even when it would be used for gambling, who cares? It would be a currency mostly used for gambling then simply.
And only because of missing adoption a currency does not lose it's status as currency, don't you think?
