i think it will stabilize around 1800 before and after the first block halving. and it will stay near there until 7 days later at the second block halving. 2300 after the second block halving is my guess. after that, i'm not sure.
Usually the markets already price in the block halving , just like it happened before in the case of doge.
There will be no miraculous rocket the moment the reward is cut.
