The halving is coming, the userbase is increasing, what could make Bitcoin's price fall ? Nothing right now. Even if Bitcoin loses users, the price will still grow due to the 2 halvings that will happen in a 4-years time span.
The exchange price of bitcoins is driven by speculation and demand along with supply.
The halvings will not decrease the existing supply in any way. After each halving, the number of bitcoins will still be increasing. The halvings should have little to no effect on the price on way or the other.
