I'll say that sky is the limit if it's about the truest potential and price of bitcoin in the future. Take all of those halvings for example and when we say long term, it'll depend on how long you're looking at it.
With halving, as the reward for the mined blocks will become lesser for the miners. That will result to the lesser supply and higher difficulty for it to mine a block and as well as higher price.
Well, I don't have a price in my mind but I'm very much optimistic and waiting for it to come. Many might laugh at us for now if we tell them about 6 to 7 digits but who knows, right?
