Youre just being practical because the competition is in actual time but if we will apply this in the future for fairness lets say when the adoption had already happen for sure that your stand will change and choose Bitcoin instead.
So for today I choose USD over Bitcoin because as what you have stated thats true and in practical ways
But I am willing to edit this post in future if half of the world acknowledge cryptocurrency already because by that time I am sure bitcoin will dominate even the strongest fiat in the world like Dollar
