Halving events have frequently been associated with increase in price of bitcoin with significant upward momentum both before and after halving. Bitcoin halving often generate increased market attention and hype. Expectation of lower supply and likely price increase may fuel positive feelings amongst investors and traders.
What is certain is that after the halving occurs, prices will not immediately rise as everyone dreams because the potential for a down trend after that is also very vulnerable and high. But, after that everything is normal Bitcoin will continue to break the previous ATH record where increasing interest grows upwards and most likely it could reach another record high again because many want to take advantage of the price swings in it.
