To your last point, I’d like to point out there’s an adage that goes along the lines of “the market can stay irrational longer than you can stay solvent…”

Very true, which is part of why I don't have any positions on anything myself. But OP had a timeframe of 'until the end of the year'. If I felt strongly about something and had a timeframe like that, I'd place some bets.

But why would you expect someone else to behave like you in this tiny betting niche?

Good question. I guess I don't have any expectation that someone would. I was just stuck by the somewhat aggressive tone and strength of their statement. When people talk so aggressively I prefer to see them putting their money where their mouth is.
