theymos (or some famous members) already said somewhere that this would make the forum have the "too much price dependent" vision.
1 BTC = 1 BTC. And that's what matters.
This pretty much. As if we didn't have enough threads about the price or something. Also, if you wanted to check the price then just head over to coinmarketcap or coincap or whatever your preferred marketcap site. If there were to be something on the header part, I'd prefer some statistic like bitcoin dominance or something(but then again, this can be accomplished simply by going to certain sites).
