It’s a question with no definitive answer. There are miners who are only doing this as a business, institutions only buying Bitcoin for short term profit, devs maybe doing this just for the sake of their job (there were rumors before that Coinbase will hire Bitcoin devs but idk if they ever did), etc.

On the other hand, the opposite of all the above exists too. After all, it’s all about who believes Bitcoin can succeed.

For the sake of this thread though, I’d say generally it’s the miners and devs being most bullish, followed by institutions and finally the noobs. Noobs deserve last place because they’re only bullish when Bitcoin’s bullish.

If you're to consider the list you gave, you will discover that bitcoin miners has the most demanding aspect of them all as it both requires the mining technical skills, requirements for setting up a bitcoin mining rig and also the difficulty into solving a complex mathematical equations to be the one to appear first to finish this minig task to be rewarded with bitcoin, so bitcoin miners are the most demanding of them all and the sole basic background that creates an avenue for us all to have bitcoin to trade, hodl and invest, miners also have their little way of facing a serious challenge under regulations except for those that have learnt to remain independent of the government approved energy source.

Not all, because some people are into cryptocurrency but do not have Bitcoin in their wallets because they are here to make quick money, and they think Altcoins will give them the money on time.

I also wondered how miners would survive this extended bear market because the payouts they were receiving were not more than they were before to the bear market. As a result of the cost of their upkeep and expenditures to keep them mining, I believe miners are the most bullish in this position.

I'd say the noobs everytime, generally with wild expectation of another 100% increase in Bitcoin's price within a few years. I don't really see the miners or developers being that bullish, as either way they are generating income from Bitcoin's existence, so generally speaking speculating on the price isn't necessary, even if remains profitable. As for the institutions, sure they can be bullish to some degree or another, but generally it's about wealth preservation as opposed to wealth accumulation, so they allocate their % or two into Bitcoin in order to maintain the wealth they have already accumulated.

I don’t think there’s any question about who is the most bullish of this list we had to choose from. Bitcoin institutions are of course going to be the most bullish by nature as that is quite literally how they make a living, that is their business. So I feel like even if they didn’t believe it, they are still going to act like or say that they are bullish to try and help pump bitcoins value.

Bullish means: the one who thinks BTC will break its ATH in the next bull run after halving. (it is my opinion so) If we take this definition into account and try to select which of the above option is more bullish then i think the Noob category might fall into this. (like me, yeah i am also nooB). The point is, Noobs can easily fall prey to market sentiments just like the current situation.

I wrote a post yesterday, about how HSBC bank's enabling the BTC ETFs is not big news but media outlets are showing it like big news and many newcomers are taking it like "Oh wow, BTC is going to adopt globally now" but we all know that such news made no bigger impact until they play their role in manipulating investor's and trader's mindset.

I also read a post in which OP shared his thoughts about a halving of BTC. As most of the people involved or new to crypto think that in this halving, the BTC will going to reach $100k easily. But the Op's idea reflects different things. point is if that becomes true then what are the people's mindset will be in 2026, will their trust halving? (TBH, my idea is maybe not as when many people know the secret, then the secret ingredient becomes useless).

It's a shame that only a few people voted so far, but I still chose the most popular option: the last one. Bitcoin miners get new coins, and overall I don't think they are a big part of those who closely follow the market. It's often costly to stop the operations and then restart them, so if miners probably push through the tough times if they can. Bitcoin Core developers are the farthest, I believe, from the pricing and stuff, as they are focused on the technology and maintaining it. Bitcoin institutions aren't bullish enough, clearly, because we'd have a much better market situation if they were. The newbies, on the other hand, are often very hopeful and misguided, thinking that Bitcoin will bring them great profits pretty fast, so they are probably the most bullish. That being said, they're probably also those who panic the most when Bitcoin starts losing value.

There is a 5th group of people who the OP has totally forgotten, thats "Bitcoiners" ! those
of us who dont fit into the 4 categories provided. I am a Bitcoiner, not a noob, developer,
node runner or miner and I believe I am part of the biggest group, regular Bitcoiners who are
generally bullish especially at this current time approaching the halving.

So from the 4 groups listed in the poll I cannot cast my vote because collectively and
generally speaking we are all bullish.

Op, be it Bitcoin miners, core developers, Bitcoin noobs, and institutions, the mission is still identical, which is seeing Bitcoin succeed.
If you further reduce these categories of Bitcoiners just into two groups, contributors and investors, and in your opinion that miners are the most Bullish Bitcoiners in the space I disagree with you, rather I would like to pick institutions that fall under investors, reason miners are already on profits right from the time institutions (investors) enters the market leaving institutions with expectation of price increase to profit, hence making them the most bullish.
