@JayJuanGee ... I'm still massively bullish on Bitcoin, but I don't see any future for BTC. It's a long story, which nobody is interested in so I won't waste anyone's time

Sounds contradictory just the way you stated it, and of course, not too many people are interested in BIG blocker nonsense or any of that kind of snake oil baloney in a bitcoin thread, and maybe we are getting a bit off the topic if we go into descriptions about what is consensus, which ends up driving the direction of BTC in terms of Schelling point type dynamics.
If you read between the lines he just means BTC is not Bitcoin anymore, another alt coin is the real Bitcoin (pretty clear from his previous posts)

Fair enough. I kind of read back about some of sgbett's previous stances to better understand regarding his point of view situation.
So, ultimately merely because he believes that bitcoin is no longer the real bitcoin, the topic of this particular thread has NOT changed to something other than being about bitcoin, as far as I can tell. And, maybe that is where the Schelling point concepts come to play out?
Of course, anyone can attempt to make certain arguments about bitcoin transitioning to some other status or needing to transition towards a certain status, but that seems to be a topic of another thread - when this one is about bitcoin prices and bitcoin price dynamics, rather than being about "what is bitcoin?"
