Someday the price for bitcoin will reach $ 100k+, this is how this system works thanks to halving and limited emission.
In my opinion, bitcoin approval is slightly exaggerated and it is now only in the initial stages. BTC still have to overcome many difficulties and obstacles. But I don't think that bitcoin can be forgotten, because this phenomenon has already had a very strong impact in the world.
I think the situation with bitcon will be approximately identical to what it was in previous years: price drops on corrections and ups after halving (traditionally with some delay).
The credit will still go the investors because without them those other factors that you said are going to be nothing. People always believe that halving can increase the price, idk if this is true but maybe the reason why price will increase is because many people are going to buy more bitcoins in preparation to the halving event.
Is limited emission you mean, btc mining will become more greener? If that is then it can also magnet investors, big investors like Elon Musk because Elon wants this to happen long time ago. Obviously the price will always drops whenever there is a correction but prices can recover again even without halving.
