I would like if someone could explain this to me. How someone who is mining BTC can be a bull? I mean miners sell at some point for whatever reason don't they?
As a miner, I will try to answer your question, but first, the preamble:
sure, I'm a miner, and I have a small portion of my mined funds that I play around with on the exchange. I also have mined well over 1000 bitcoins yet I now have less than 50 left to show for it.
I still think I classify as a bull, even though I may have thrown away a fortune. If I didn't have the foresight or the belief that bitcoin would succeed then I never would have upgraded my hardware and never come close to 1000 bitcoin, (though I still might have reached 50)
I think there is great potential for the bitcoin protocol, but I have very little spare fiat to invest, so I very slowly mined bitcoin and then bought additional mining capacity as time went on. I have made some mistakes and some incredibly profitable purchases along the way.
My thinking was always that I felt it was more important to *know* about bitcoin and how it works than to just *have* bitcoin.
I must admit that I don't understand every little detail or nuance of the bitcoin protocol, but I have almost 3 years first-hand experience with how it works, and I think that's worth something.

So, in an attempt to answer "How someone who is mining BTC can be a bull?"
A miner is intrinsically linked to the bitcoin system. A miner might simply want to cash out immediately into fiat, or might want to hold. The simple fact is that in both scenarios a higher bitcoin price is the desired outcome. If one felt that the price was going to drop, especially in the face of the exponential increase in difficulty, that person would likely sell their hardware, and would no longer be a miner.
Now that I think about it, I'm not sure how one could even be a miner without being a bull?
