... I look forward to intelligent, reasoned arguments for how Bitcoin will again find a value north of $300.
Never is a long time. The US dollar is an empire-backed currency, Bitcoin is a distributed ledger protocol on the internet. Which of these do you think has the longer lifespan?
Historically speaking empires have lifespans measured in single digit centuries.
Fine, I'll narrow the scope of my statement:
"Bitcoin will never again be priced over $300, for so long as the United States Dollar and/or the Euro and/or the Chinese Yuan exist as the world's de facto reserve currencies."
Better?
