However, as said, who cares? Especially as it's agreed that we're still in the bull market.
And no matter what, on the long term (~4 years) it will surely rise (too) big time, so we're just fine.
I'm an optimist too, and since I'm going long term, I don't care much about this sideways. What I do wonder is what would happen if for whatever reason the price goes below $20K. It would be breaking a historical trend, and there some predictive models would have to be rethought.
In any case, I don't think it will happen. I also think we've already hit the bottom and when the price goes up and breaks $40K again, we're going to $100K easy.
