who said it was going down?
The people who were saying that difficulty follows price.
I think it rather follows value. Value is not always the same as price. For instance, as I think Bitcoins are going to rise by several factors in the next years and I think long term their value for me is much higher than it's current price.
Makes sense, yet at the same time it's an arguable subject. Who's to say that price doesn't actually follow difficulty? But the price just "hasn't caught up yet" either. Chicken or the egg, you pick.
Difficulty affects price and vice versa, but there are other factors to consider as well.
Usually when I see something be referred to as a
Chicken or the egg problem it's simply a misunderstanding of logic or the nature of the specific underlying problem. This is no exception, what you're talking about is a feedback loop, there is nothing weird about it and is omnipresent in everyday systems, including our body. The "Chicken or the egg problem" itself arises from inconsistent definitions, it's the same as asking whether a fixed object would move when pushed by an irresistible force.
