The Bitcoin halving period could be a crazy time for Bitcoin and cryptocurrencies. Expect the price to go up and get a new ATH after each halving, so expect to hit a new all-time high after the next halving. Of course Bitcoin users and popularity will also increase.
Some posts above
Bitstar_coin showed, that during last 3 halvings Bitcoin price did not show any major changes. At previous halving, a lot of people expected Bitcoin price to skyrocket, but the significant price change started after Elon Musk tweets. This time the world economy is in tricky situation, and Elon Musk shows low interests in crypto, so instead of huge price changes, I would expect no huge price changes at all.
And btw, you say "new ATH after each halving" - there was never a new ATH after halving. Bitcoin had ATH 1-2 years after halving.
Elon just entered the market in 2021, how can it be said that Elon created the growth of bitcoin? He is not a bitcoin creator or god to be able to do that, if he can tweet to make bitcoin hit new ATH, then I believe he has done it many times for his purpose of manipulating the market for profit. The fact that bitcoin always generates ATH after each halving means that bitcoin will not spike and reach ATH immediately, but it takes time, maybe half a year or a year later. Elon is not the savior of the market, he is just an investor like us, trying to follow the market to make a profit.
