Somehow people never say that 1 BTC = 1 BTC when it's the bull market and everyone is fixated on its USD price, but when there's a bear market, we should all forget about USD price 

This crash like any other bear market shouldn't be downplayed. It's a sign that Bitcoin still operates on the basis of speculative boom-bust cycles, so it's not really a strong safe haven asset that can rival gold.

Sure, Bitcoin will recover and reach new highs, but it doesn't mean that crashes like this one don't matter at all.
