So here's how I read the current sentiment around this forum: most people who watched 2011 happen here are now expecting a dump. Most newbies aren't.

2011 bitcoiners are mostly middle-class geeks not pro investors. Their fun-money has suddenly become something you can buy real estate with. At that level there is little point for them in buying more coins with their monthly spare cash - it's like adding a few dimes to a million.
Most of them were true believers at the beginning, yet now I'm not sure most of them still are - to the point they'd actually spend their coins.
Their stash's potential worth keeps oscillating between "decent car" and "financial empire", depending on the news of the day.
So much at stake doesn't make you sleep at night. Turns you into a zombie checking tickers and watching walls.

Newbies - they are coming late to the party and are likely in for the get-rich-quick hype. They don't have the 2011 bias. It's like fathers vs kids. Fathers have cognitive bias so they are uneasy to adapt to new conditions. Kids have inexperience bias so they are likely going to make the same mistakes again.

And then there are speculators. Pro speculators. Likely silent lurkers here. Maybe we are all being played by a few pro's of them who just need to get all the coins for their own play, and are ok with burning some serious amount of fiat in the process. I don't know.

I think BTC price is like Schroedinger's cat. The simple act of us observing walls and talking about them makes it so that they move in the opposite direction of where the most of us expect them to. And yes I think the dump will happen. But only when almost nobody is expecting it anymore. Which makes it hard for us to get profit on the way up.
