EVERYONE in this forum is a bull, even the ones that claim to be bears because if you were a bear, you wouldn't care about bitcoin and you wouldn't be in this forum to begin with.
I disagree!
If we define "bull" as "one who expects the BTC price to rise", and "bear" as "one who expects the BTC price to fall", I can imagine plenty of reasons to be interested in the Bitcoin technology that don't imply bullishness - even long-term bullishness.
There are people who think that the blockchain technology is the future of currency, but see the Satoshi implementation as riddled with instabilities or bad design decisions that will require a new blockchain to (and thus, the eventual abandonment of BTC as current money) to resolve.
There are people who simply believe that the practical use of BTC is too niche to justify a half-billion total nominal value - who reject the "rocketship or nothing" dichonomy and expect the price to eventually stabilize at something more like $13/coin.
There are miners who think BTC will fail in the long-term, and are just here to get their block rewards (cashed out for fiat) until it happens.
And that's not even counting all the people who think BTC will go to the moon in a hundred years, but think it'll revisit $2 before it gets there.
