Out of the 4 categories that you listed, it's easily the Bitcoin noobs.
The developers don't care that much about the price, they are focused on making Bitcoin better because it's their passion. The miners and institutions are first of all focused on profits. They don't need Bitcoin to go up and up to profit, they just need it to not crash too hard. As long as the price is not too low, they will be collecting fees and making profit.
So, only noobs here are the most interested in Bitcoin going up, because that's their whole strategy - getting rich quick.
Of course, the noobs are the most bullish because in their minds they have the most to lose. When you have very little, every penny counts.
Miners sell bitcoin every month to pay their electricity bills, they aren't top bulls, to them it's just business.
Institutions usually hold their coins on exchanges or with custodials. They're always ready to sell at a sign of failure. Microstrategy is a special breed because Saylor is an extreme bull, but most companies are ready to sell at any moment.
Core developers don't continue to invest. They may hold some bitcoin but they don't stack every satoshi like some people here on the forum.
I do not belong to any of these groups. I'm just a simple saver who prefers to spend fiat and save in bitcoin.
